Abstract:

Arthroscopic surgery is a minimally invasive surgical procedure that is widely used on joints. However, conventional endoscope-based arthroscopic surgery does not provide stereoscopic information to the surgeon. To overcome this limitation, we have developed a modified endoscopic system that uses an optical fiber (1 mm diameter) for three-dimensional imaging of knee joints. Our endoscopic system is able to operate underwater in real time. It consists of a laser beam that is projected on the surface of the object to be imaged via an optical fiber. A prism is used to decrease the length and diameter of baseline and endoscope tube, respectively. The small diameter (8 mm) of our endoscope makes it extremely convenient for application in arthroscopic surgery. The feasibility of the proposed system has been demonstrated via experiments on synthetic knee joints.

Abstract:

Objective: Primary varicose veins below the knee were managed with the assistance of endoscopic surgery in 240 limbs (235 cases). Methods: Patients were classified into five clinico-anatomic types according to associated normal veins involved in the varicosities. All procedures were limited to below the knee. With the superior illumination and magnified monitor view offered by the endoscope, all the varicosities and the incompetent perforating veins were dissected, clipped, divided and removed through one or more access incisions (2.5–3.0 cm in length). However, the normal veins were preserved, including the long saphenous vein. Results: The mean number of incisions in each limb of all patients was 1.86. As there were no residual varicosities or incompetent perforating veins, there was little possibility of recurrence. In the follow-up of 218 limbs, recurrence occurred in only two limbs. Conclusion: Endoscope-assisted surgery is a good alternative for management of primary varicose veins below the knee, resulting in low recurrence and aesthetically acceptable surgical scarring.

Abstract:

Between October 1996 and August 1997, 56 endoscopic vein harvests were performed with video monitoring. Incisions of 2 to 3 cm in length were made at the groin and above or below the knee. The harvested veins were used for coronary artery bypass grafting. The complication rate was 1.8%. The average hospital stay for patients undergoing the endoscopic procedure was 7.2 days. All incisions had healed well at the 12-week follow-up. Endoscopic saphenous vein harvest provides a minimally invasive alternative to the open procedure. It gives a good cosmetic result, promotes early ambulation, and may reduce postoperative pain.

Abstract:

Three-dimensional (3D) navigation using a computer-assisted technique is being increasingly performed in minimally invasive surgical procedures because it can provide stereoscopic information regarding the operating field to the surgeon. In this paper, the development of a real-time arthroscopic system utilizing an endoscopic camera and optical fiber to navigate a normal vector for a reconstructed knee joint surface is described. A specific navigation approach suitable for use in a rendered surface was presented in extenso. A small-sized endoscopic tube was utilized arthroscopically on a cadaveric knee joint to show the potential application of the developed system. Experimental results of underwater navigation on a synthetic knee joint showed that our system allows for a higher accuracy than a freehand technique. The mean angle of navigation for the proposed technique is 9.5circ (range, 5circ to 17circ; SD, 2.86circ) versus 14.8circ (range, 6circ to 26circ; SD, 7.53circ) and 12.6circ (range, 4circ to 17circ; SD, 3.98circ) for two sites using a freehand technique.

Abstract:

Abstract BACKGROUND Proximal lesions of the sciatic nerve are often difficult to diagnose and to treat properly. In particular, if there are posttraumatic or postoperative alterations, imaging might not identify the level and location of lesion. Due to the sciatic nerve anatomy, the same is true for clinical and electrophysiological evaluation with a risk of delayed surgery and, thus, unsuccessful surgery. Therefore, in some unclear cases, surgical exploration of the whole sciatic nerve and its divisions could be the only means to determine the correct diagnosis and allow prompt treatment to produce the best clinical outcome. OBJECTIVE To describe a novel minimally invasive technique to explore and treat patients with proximal sciatic, peroneal, and tibial nerve lesions. Intraoperative findings, surgical considerations, and complications are presented. METHODS From January 2012 to November 2013, 9 consecutive patients with lesions of the sciatic, peroneal, and tibial nerves underwent endoscopy and were treated. The technical considerations of these cases are presented with regard to the retrospectively collected clinical and surgical data to evaluate the pros and cons of the technique. RESULTS A subgluteal incision, as the primary endoscopic port, was used in all 9 patients. An additional mid-thigh and fibular head incision was thought necessary in 3 patients. An extension of the approach by a secondary transgluteal incision was performed in 4 patients. In 2 of these sciatic lesions, autologous nerve grafts were placed. One perineurioma was detected and bioptically secured. There were no complications. Six patients experienced pain relief; in 6, we observed motor improvement. The mean follow-up was 9.5 months. CONCLUSION The endoscopically assisted single- to multiportal sciatic exploration technique provides excellent visualization that enables nerve inspection, lesion detection, and decompression, and obviates the need for more extensive approaches in cases of unclear sciatic nerve pathology. By adding several ports, whole-length exploration of the sciatic from the notch to fibular head level is feasible.

Abstract:

AbstractBackground:Robot-assisted surgery is considered to improve ergonomics over standard endoscopic surgery. Nevertheless, previous research demonstrated ergonomic deficits in the current console set-up.Aim:This study was designed to objectively assess body posture in the da Vinci console during robot-assisted endoscopic surgery.Methods:Multiple sagittal photographs from six physicians were taken during robot-assisted procedures. Trunk, neck, shoulder, elbow, hip, and knee angles were calculated and compared to ergonomic preferable joint angles. A 2D geometric model was developed using individual anthropometrics. Optimal seat height, armrest height, and viewer height were calculated. These results were compared to the findings of the sagittal photographs.Results:Mean joint angles show potentially harmful neck angles for all participants. Trunk angles vary between surgeons, from inadequate to correct. In short and very tall individuals, optimal armrest height is outside the adjustment range of the console.Conclusion:The da Vinci Surgical System console seating position results in a nonergonomic neck and trunk angle. The developed geometric model revealed that armrest height has a limited adjustment range. Adjustments to the console and optimization of preoperative settings are goals to further improve ergonomics in robot-assisted surgery.

Abstract:

Osteomyelitis caused by Mycobacterium species may be difficult to diagnose and treat. We report a case of treatment for osteomyelitis caused by Mycobacterium species in the epiphysis of the right proximal tibia. A 28-month-old boy presented to a hospital with symptoms of fever and right knee pain. He had been vaccinated with Mycobacterium bovis Bacille Calmette-Guérin (BCG) at five months of age. The epiphyseal radiolucent lesion had increased in size and extended to the metaphysis through the physis on a plain radiograph of the right proximal tibia. Surgical drainage and curettage of the lesion were performed with an endoscope under C-arm fluoroscopy. The intraoperative histopathological examination revealed granulation tissue composed of caseous necrosis and Langerhans giant cells, revealing Mycobacterium species to be the causative pathogen. Because of suspected osteomyelitis caused by BCG, the antituberculosis drugs were administered orally from an early postoperative stage. A plain radiograph taken eight months postoperatively showed bone regeneration in the area of curettage and a slight physeal bridge, in addition to normalization of the inflammatory response on blood sampling. It was possible to perform accurate diagnosis and rapid treatment for epiphyseal osteomyelitis caused by Mycobacterium species using endoscopic surgery under fluoroscopic guidance.

Abstract:

The problem of diagnosis and treatment of chronic anterior-posterior instability of the knee joint in multi-ligamentous injuries remains relevant, both medically and socially. Conservative treatment of patients with this pathology is ineffective due to severe instability and gross violation of the biomechanics of the knee joint. Currently, there is no consensus on the tactics of surgical treatment of this disease, and on the method of plastic replacement of the lost ligamentous apparatus. Objective. To evaluate the clinical results of the modified technique of arthroscopic plastic surgery of both cruciate ligaments of the knee joint. Patients and methods. Based on previous anatomical studies, the authors formulated the basic principles of safe formation of bone tunnels in simultaneous arthroscopic plastic surgery of the anterior (PKS) and posterior (ZKS) cruciate ligaments. An original method of surgery aimed at minimizing the risk of injury to the popliteal artery during the formation of the tibial bone tunnel is proposed. In the period from 2010 to 2017, the Department of endoscopic surgery treated 20 patients with damage to the SCS and SCS using this technique. The results were evaluated 6 and 12 months after surgery. Clinical examination, IKDC and Lisholm-Gillqist questionnaires and the visual analog pain assessment scale (VAS) were used to evaluate clinical results. Results. The average score on the IKDC questionnaire was 34.16±13.31 points before surgery, and 34.89±18.37 points on the lisholm - Gillqist questionnaire. 6 months after surgery - 58.75±6.38 and 69.78±14.10 points according to IKDC and Lisholm-Gillqist, respectively, which is statistically significant (p

Abstract:

The world literature on malignant polyps suggests that those removed endoscopically with recognized favorable histological features for conservative management have excellent prognoses without surgery. Many sessile or 'uncertainly removed' malignant polyps after endoscopic polypectomy also show no evidence of residual cancer, suggesting that referral for surgical resection is not invariably in the best interests of elderly or poor surgical risk patients. St Mark's experience of five year follow-up of 62 patients with malignant polyps judged 'completely excised' showed three cancer-related deaths (of uncertain primary) in 78- to 81-year-old patients. Of 18 patients with malignant polyps 'incompletely excised,' seven had no cancer found at surgery, 10 were well without surgery and one died from carcinomatosis following delayed surgery. These generally encouraging results are further evidence that 'knee jerk surgery' for malignant polyps is inappropriate.

Abstract:

Aim. To compare patency of aortocoronary bypass grafts in remote period after endoscopic and conventional (open) great saphenous vein harvesting. To analyze the patency of aortocoronary bypass grafts after endoscopic vein harvesting from calf and thigh.Methods. The study involved 170 patients who underwent elective isolated coronary artery bypass grafting. Treatment results were evaluated in two prospectively formed groups: endoscopic (85 patients) and open (85 people) vein harvesting. Endoscopic vein harvesting was performed both from the calf and from the thigh through popliteal access using endoscopic system Vasoview 6.0. Patency of autovenous aortocoronary grafts was studied in 2.6±1.17 years after surgery using 64-slice contrast-enhanced MDCT or traditional angiography. Angiographic follow-up covered 76 patients with endoscopic vein harvesting and 79 patients with open vein harvesting.Results. The studied groups did not differ in the frequency of detection of occluded, stenotic and fully patent autovenous aortocoronary bypass grafts (p=0.841). In endoscopic vein harvesting group frequency of autovenous aortocoronary bypass grafts occlusion was 25.7%, in the group of open vein harvesting - 25.1% (p=0.984). There was no difference in the patency of internal thoracic artery grafts to the left anterior descending artery (p=0.227), and freedom from adverse cardiac events (p=0.342). Occlusion of autovenous grafts after endoscopic harvesting from the calf developed less frequently than after endoscopic harvesting from the thigh (15.1 vs. 34.6%; p=0.013). Grafts after endoscopic harvesting in the knee region occluded most often (41.9%). Patency of aortocoronary bypass grafts after open vein harvesting was not dependent on the area of the vein harvesting (p=0.900).Conclusion. Endoscopic vein harvesting does not compromise the patency of aortocoronary bypass graft and does not increase the risk of its occlusion; endoscopic harvesting of the veins from the calf improves indicators of aortocoronary grafts patency and reduces the risk of graft failure (odds ratio 0.3; 95% confidence interval 0.14-0.8; p = 0.013).

Abstract:

The purpose of this study was to describe a new method of gastrocnemius recession using an endoscopic approach and to determine the accuracy of incision placement during gastrocnemius recession. Fifteen fresh-frozen cadaveric limbs underwent an endoscopic gastrocnemius recession utilizing a two-portal technique. All limbs were anatomically dissected after the procedure and each was examined for injury to the sural nerve. The ability to visualize the sural nerve intraoperatively, improvement in ankle dorsiflexion, time requirement for the procedure, incision size, and appropriateness of placement to facilitate recession were recorded for each specimen. An average of 83% of the gastrocnemius aponeurosis was transected in all 15 cadavers. After modifications of the technique, the final eight cadavers were noted to have had the entire (100%) gastrocnemius aponeurosis transected. Sural nerve injury occurred in one specimen (7%) in which the aponeurosis and the sural nerve were not well visualized. The sural nerve was definitively visualized during the procedure in 5 of 15 specimens (33%). No Achilles tendon injury was noted in any specimen. There was a mean improvement in ankle dorsiflexion of 20° (range, 10°–30°) during full knee extension. The average length of time to perform the procedure was 20 minutes (range, 10–35 minutes). The average medial and lateral incision lengths used in the two-portal technique were 18 mm (range, 14–22 mm) and 17 mm (range, 12–19 mm), respectively, and the average distance from the midpoint of the medial incision to the level of the gastrocnemius-soleus junction was 26 mm (range, 5–60 mm). These results indicate that a complete gastrocnemius aponeurosis transection may be obtained utilizing a modified endoscopic gastrocnemius recession, but visualization of the sural nerve is poor with possible risk of iatrogenic nerve injury.

Abstract:

We conducted a retrospective, minimum 2-year follow-up study to evaluate the effectiveness of a single-incision endoscopic anterior cruciate ligament reconstruction technique using patellar tendon autograft without extraarticular augmentation and followed by accelerated rehabilitation. One hundred three patients were evaluated (mean followup, 36 months; range, 24 to 55). There were significant improvements in physical examination test results (Lachman, anterior drawer, and pivot shift) postoperatively, and 94 patients (91%) had negative pivot shift results. KT-1000 arthrometric testing showed a significant reduction in manual maximum anterior translation and side-to-side differences at followup. Good range of motion was achieved. Patients with asymmetric prone heel heights usually had hyperextension in the contralateral knee. Functional tests showed 4% to 6% differences in side-to-side comparisons for a timed single-legged hop, single-legged hop for distance, and vertical jump. Postoperatively, the results of the Tegner scale were similar to preinjury scores. The mean results of the Hospital for Special Surgery scale (90), Lysholm score (89), and Noyes sport function score (90) were all excellent or good. Only 5 patients (5%) required reoperations for flexion contractures. Ninety-six patients (93%) reported they were “mostly” or “completely” satisfied, and 98 (95%) would recommend the procedure to others. These results demonstrated encouraging outcome using this single-incision technique.

Abstract:

Background During the past decade, bioabsorbable interference screws have become increasingly popular in endoscopic reconstructions of the anterior cruciate ligament. With these screws, there is no need for a second operation for removal and no complicating factor if later revision surgery is necessary. Several pullout studies have found similar results between metal and bioabsorbable interference screws; however, few studies have investigated the clinical outcome. Hypothesis There is no difference in the clinical outcome of bioabsorbable interference screws compared with metal screws. Study Design Randomized controlled clinical trial; Level of evidence, 1. Methods Forty-one patients were randomized for the use of either metal interference screws (20 patients) or bioabsorbable poly-L-lactic acid screws (21 patients). The patients were followed with clinical examinations at 6, 12, and 24 weeks and at 1 and 2 years postoperatively. Results Subjective knee function was better in the patients in the metal screw group; they had less pain at rest, a higher Tegner score, a higher Lysholm score, and better subjective knee function at 2 years compared to the bioabsorbable screw group. However, there was no difference in stability between the groups. Conclusion and Clinical Relevance Because of the inferior results in the bioabsorbable screw group in our study, and until larger studies show otherwise, we do not find the advantages of using bioabsorbable screws sufficient to warrant the routine use of poly-L-lactic acid screws in anterior cruciate ligament reconstructions.

Abstract:

Background There are conflicting reports of allograft performance, immune response, tissue incorporation, and rerupture rates when used for anterior cruciate ligament reconstruction. Purpose To evaluate the clinical outcome of a fresh-frozen, nonirradiated, patellar tendon allograft for primary anterior cruciate ligament reconstruction surgery. Study Design Case series; Level of evidence, 4. Methods Patients who underwent endoscopic primary anterior cruciate ligament reconstruction with allograft tissue a minimum of 2 years ago were evaluated with physical examinations, the KT-1000 arthrometer, functional testing, radiographic evaluation, subjective assessment, and outcomes tools. Results Fifty-nine patients (60 knees) were evaluated at an average of 51 months after surgery. Ninety-four percent of patients were mostly or completely satisfied. A negative pivot shift test result was noted in 90% of subjects. The KT-1000 arthrometer side-to-side differences were = 3 mm in 95% of patients, and no patient exceeded 5 mm. The mean International Knee Documentation Committee score was 78 (SD = 19), and the mean Lysholm score was 82 (SD = 17). There were no clinical symptoms consistent with graft rejection or infection. Radiographic evaluation demonstrated infrequent significant tunnel widening. Conclusions Use of a fresh-frozen, nonirradiated allograft for primary reconstruction of the anterior cruciate ligament is a successful procedure both subjectively and functionally for restoring stability in patients selected for allograft reconstruction. In the patients selected for this surgical procedure, clinical, arthrometric stability testing, and subjective satisfaction were comparable to our previously published cohort studies using patellar tendon autograft at similar postoperative follow-up.

Abstract:

Biomimetic is the field of engineering which involves analyzing the biological beings and incorporating their designs and systems for manufacturing mechanical systems. An Ionic Polymer metal composite (IPMC) is a smart material that displays a significant bending and tip force after the application of a low voltage. It is light-weighted, flexible, easily actuated, multi-directional applicable and requires simple manufacturing. In this paper, a two-link biomimetic knee joint mechanism of a grass hopper is presented. Secondly, an IPMC pair of strips is proposed as a link that enables the actuating force which is modeled on the basis of the grass hopper's leg. Thirdly, dynamic model is developed for the proposed mechanism through Lagrangian mechanics. Fourthly, power series is utilized for the solution of the non-linear transcendental model. Wolfram mathematica is employed for the simulation of the model. Finally, the effect of torque is analyzed by varying the actuating torque. It is concluded that actuating torque is directly proportional to the angles moved and inversely proportional to the potential energies of the linkage. Furthermore, a stiffer and more vibrant linkage is observed as per simulation results. These results are validated theoretically. Our simulation results indicate that the proposed IPMC has the potential for utilization in small biomimetic applications like insects robots joints activation, underwater fish fins, surgical grippers, synthetic ventricular muscles and human catheter system for endoscopic surgery and diagnostics etc.

Abstract:

Proximal hamstring tendon injuries occur frequently in the athletic population resulting in varying degrees of functional disability depending on severity of injury. The purpose of our case vignette is to describe a surgical technique and clinical outcome for open proximal hamstring tendon repair with a confirmed biomechanically sound construct. We also describe and summarize the current literature recommendations for proximal hamstring injuries. We present a case and surgical technique report on a 27-year-old male who suffered a proximal hamstring tendon rupture. Utilizing a double row all-knotless suture bridge construct with a total of four anchors and six suture limbs allowed for anatomic footprint coverage and strength. Two years of clinical follow-up was obtained evaluating hip and knee range of motion, strength, and functional ability. Our patient underwent uncomplicated open surgical repair and returned to all activity at four months following surgery. Range of motion and strength returned to preoperative levels at the four-month postoperative mark. The use of a reproducible double row all-knotless suture bridge technique provided adequate strength and stability in the setting of a proximal hamstring tendon rupture. Open and endoscopic surgical techniques performed acutely both show positive postoperative subjective outcomes as well as a high likelihood of returning to sport. Controversy remains present in regard to the repair technique as well as postoperative bracing and physical therapy recommendations.

Abstract:

Background: No well-controlled studies have compared the long-term outcome of anterior cruciate ligament (ACL) reconstruction with hamstring tendon autograft between adolescents and adults. Increased posterior tibial slopes (PTSs) have been reported in the ACL-injured versus controls, but the effect of PTS on the outcome after reconstruction is relatively unexplored. Purpose: To compare the prospective longitudinal outcome of “isolated” ACL ruptures treated with anatomic endoscopic ACL reconstruction using hamstring tendon autograft over 20 years in adolescent and adult cohorts and to examine factors for repeat ACL injury. Study Design: Case-control study; Level of evidence, 3. Methods: A single-surgeon series of 200 consecutive patients undergoing isolated primary ACL reconstruction with hamstring tendon autograft were prospectively studied. Subjects were assessed preoperatively and at 2, 7, 15, and 20 years postoperatively. Outcomes included International Knee Documentation Committee (IKDC) Knee Evaluation, IKDC subjective scores, KT-1000 instrumented laxity testing, and radiological evaluation of degenerative change and medial tibial slope. Twenty-year outcomes were compared between those who underwent surgery at the age of 18 years or younger (adolescent group, n = 39) and those who underwent surgery when older than 18 years (adult group, n = 161). Results: At 20 years, 179 of 200 subjects were reviewed (89.5%). ACL graft rupture occurred in 37 subjects and contralateral ACL injury in 22 subjects. Of those with intact ACL grafts at 20 years, outcomes were not statistically different between adolescents and adults for the variables of IKDC subjective score ( P = .29), return to preinjury activity level ( P = .84), current activity level ( P = .69), or degree of radiological degenerative change at 20 years ( P = .51). The adolescent group had a higher proportion of grade 1 ligamentous laxity testing compared with the adult group ( P = .003). Overall, ACL graft survival at 20 years was 86% for adults and 61% for adolescents (hazard ration, 3.3; P = .001). The hazard for ACL graft rupture was increased by 4.8 in adolescent males and 2.5 in adolescent females compared with adults. At 20 years, the ACL survival for adolescents with a PTS of ≥12° was 22%. The hazard for ACL graft rupture was increased by 11 in adolescents with a PTS of ≥12° ( P = .001) compared with adults with a PTS <12°. Conclusion: Repeat ACL injury after isolated ACL reconstruction is common, occurring in 1 in 3 over 20 years. In the absence of further injury, isolated ACL reconstruction using this technique was associated with good long-term outcomes with respect to patient-reported outcomes and return to sports, regardless of age. However, mild ligament laxity and ACL graft rupture after ACL reconstruction are significantly more common in adolescents, especially adolescent males, compared with adults. PTS of 12° or more is the strongest predictor of repeat ACL injury, and its negative effect is most pronounced in adolescents.

Abstract:

Introduction: ACL reconstruction with autografts in the young is associated a higher incidence of repeat injury when compared to adults. This led the authors to consider alternative graft material for the ACL deficient young population. This study was performed to assess the survival of ACL reconstruction with a living related hamstring tendon autograft in a large series of juveniles and adolescents. Aim: To determine the survival of the ACL graft and the contralateral ACL (CACL) after primary ACL reconstruction with living donor allograft in patients aged < 18 years and to identify the factors that increase the odds of subsequent ACL injuries. Methods: Patients having undergone primary ACL reconstruction with a living donor hamstring tendon allograft at age <18 years between 2005 and 2014 included in a prospective database were considered for this study. Patients completed a subjective survey involving the International Knee Documentation Committee (IKDC) questionnaire in addition to questions regarding current symptoms, further ACL injuries, family history of ACL injury, and current level of activity. Results: A total of 218 adolescents (mean age 14.7, age range, 8-17 years) met the inclusion criteria and were reviewed at a mean of 48 months after surgery. Of these, there were 51 ACL graft ruptures (23%) and 26 contralateral ACL ruptures (12%). The 1, 2 and 5 year survival of the ACL graft was 88%, 80% and 74%. The 1, 2 and 5 year survival of the contralateral ACL was 99%, 93% and 85%. Survival of the ACL graft was more favorable in those with open growth plates (93, 90, 85 at 1,2 and 5 survival) compared to closed growth plates (86, 75, 68 at 1,2 and 5 year survival), odds ratio 2.3 (95% CI 1.1 to 4.8, p=0.03). A return to preinjury level of activity was reported by 79%, and the mean IKDC score was 92 of a possible 100. A positive family history of ACL injury was present in 35%. Conclusion: Further injury after ACL reconstruction in the young presents a challenging problem. ACL reconstruction using a living related donor allograft is associated with high rates of return to sport and good subjective outcomes. This technique may be considered a viable option for ACL reconstruction in the young patient with open growth plates, but does not appear to reduce further injury in older adolescents.

Abstract:

Regarding the lack of interactivity for Virtual Knee Arthroscopic Surgery, which leads less immersion in simulated surgery, a new advanced interactive device in Virtual Knee Arthroscopic Surgery based on displacement sensor and Data acquisition card was developed. Based on study of degree of freedom on Knee Arthroscopic Surgery, a new interactive device on simulating real surgery was proposed. This device simplifies true operation for four degrees of freedom. Each displacement sensor captures information from one degree of freedom, then sends the information to the data acquisition card to carry out analysis and treatment for the purpose of synchronization on the computer, then realize realistic simulation of surgical procedures. The creative design of the interactive device makes it possible to flexibly adjust the location and angle of simulated scalpel and endoscope according to different operator and reach the requirement of immersion of virtual reality.

Abstract:

Background: Increased femoral tunnel widening and weakness of the hamstring muscles postoperatively have been described as potential adverse events after anterior cruciate ligament (ACL) reconstruction (ACLR) with a hamstring graft. Meniscectomy and cartilage lesions are important factors for the development of degenerative osteoarthritis. Purpose: To compare 15-year follow-up data with 5-year follow-up data from the same cohort of patients after ACLR with a hamstring autograft using an outside-in technique. Study Design: Case series; Level of evidence, 4. Methods: A total of 72 patients who underwent anatomic ACLR with a quadruple hamstring graft and an outside-in technique were selected for this prospective study. Patients were reviewed at a minimum follow-up of 15 years. Results were compared with the same series of patients previously reviewed at 5 years after surgery. Lysholm, International Knee Documentation Committee (IKDC), and Tegner scores as well as KT-1000 arthrometer measurements were obtained at final follow-up. Comparative weightbearing radiographs were obtained and analyzed according to the Fairbank, Kellgren-Lawrence, and IKDC classifications and used for the tunnel evaluation. Results: No significant difference was detected on the subjective evaluation. Objectively, patients categorized as A or B according to the IKDC score were not significantly different at 5 and 15 years ( P < .01). A KT-1000 arthrometer side-to-side manual maximum difference >5 mm, a pivot shift >2+, any giving-way episode, and ACL revision surgery were considered as failures, and these were noted in 6 patients at 5 years and 6 patients at 15 years. The radiological evaluation at 15 years showed a higher rate of osteoarthritis in 2 of 3 radiological scales used in the study compared with results at 5-year follow-up ( P < .01). At 15-year follow-up, there was a statistically significant reduction in the mean tibial tunnel diameter ( P < .01). Conclusion: Endoscopic single-bundle ACLR using hamstring grafts and an outside-in technique demonstrated good results at 15-year follow-up in terms of subjective, objective, and radiographic evaluations. As compared with 5-year follow-up, clinical results remained stable both subjectively and objectively. However, a progression of osteoarthritis changes was observed, especially in patients in whom meniscectomy had been performed.

Abstract:

BACKGROUND: Bariatric surgery, especially Roux-en-Y gastric bypass is an effective treatment for refractory morbid obesity, causing the loss of 75% of initial excess weight. After the surgery, however, weight regain can occur in 10-20% of cases. To help, endoscopic argon plasma coagulation (APC) is used to reduce the anastomotic diameter. Many patients who undergo this treatment, are not always familiar with this procedure and its respective precautions. AIM: The aim of this study was to determine how well the candidate for APC understands the procedure and absorbs the information provided by the multidisciplinary team. METHOD: We prepared a questionnaire with 12 true/false questions to evaluate the knowledge of the patients about the procedure they were to undergo. The questionnaire was administered by the surgeon during consultation in the preoperative period. The patients were invited to fill out the questionnaire. RESULTS: We found out that the majority learned about the procedure through the internet. They knew it was an outpatient treatment, where the anesthesia was similar to that for endoscopy, and that they would have to follow a liquid diet. But none of them knew that the purpose of this diet was to improve local wound healing. CONCLUSION: Bariatric patients who have a second chance to resume weight loss, need continuous guidance. The internet should be used by the multidisciplinary team to promote awareness that APC will not be sufficient for weight loss and weight-loss maintenance in the long term. Furthermore, there is a need to clarify again the harm of drinking alcohol in the process of weight loss, making its curse widely known.

Abstract:

Background: A continued technical challenge for surgeons performing bone–patellar tendon–bone anterior cruciate ligament (ACL) reconstruction with endoscopic techniques is graft-tunnel mismatch. If tibial tunnel and intra-articular distances could be reliably estimated, surgeons could adjust the length of the femoral tunnel to minimize graft-tunnel mismatch. Purpose/Hypothesis: To determine whether arthroscopic measurement of the following was reliable: femoral tunnel distance (FTD), tibial tunnel distance (TTD), intra-articular distance (IAD), and total distance (TD; sum of these 3 measurements). It was hypothesized that intraoperative measurement of these distances would be reliable. Study Design: Controlled laboratory study. Methods: Eight sports fellowship–trained orthopedic surgeons independently performed arthroscopic measurements of the FTD, TTD, IAD, and TD in 7 cadaveric knees in which femoral and tibial tunnels had been drilled. Each surgeon performed the measurements twice using an EndoButton depth gauge. Following this, each parameter was measured open with a medial parapatellar approach. Finally, a computed tomography (CT) scan of each knee was performed, with the FTD, TTD, and IAD measured by a musculoskeletal radiologist. Inter- and intrarater reliability of the arthroscopic measurements was calculated, as well as the correlation between arthroscopic measurements and open and CT measurements. Results: Interrater reliability for the arthroscopic measurements was 0.8 for FTD, 0.89 for TTD, 0.61 for IAD, and 0.76 (range, 0.54-0.93) for TD. Intrarater reliability was 0.94 for FTD, 0.97 for TTD, 0.83 for IAD, and 0.93 for TD. The correlation between arthroscopic and open measurements was 0.9 for FTD, 0.94 for TTD, 0.4 for IAD, and 0.84 for TD. The correlation between arthroscopic and CT measurements was 0.85 for FTD, 0.92 for TTD, and 0.71 for IAD. Conclusion: The results of this study show that arthroscopic measurement of FTD and TTD has a high degree of intra- and interrater reliability, while that of IAD and TD demonstrates high intrarater reliability but moderate interrater reliability. Clinical Relevance: Reliable measurement of the TTD and IAD can potentially allow adjustment of the FTD, minimizing graft-tunnel mismatch in endoscopic ACL reconstruction.

Abstract:

AbstractObjective:To investigate whether stratification of the risk of developing a surgical-site infection (SSI) is improved when a logistic regression model is used to weight the risk factors for each procedure category individually instead of the modified NNIS System risk index.Design and Setting:The German Nosocomial Infection Surveillance System, based on NNIS System methodology, has 273 acute care surgical departments participating voluntarily. Data on 9 procedure categories were included (214,271 operations).Methods:For each of the procedure categories, the significant risk factors from the available data (NNIS System risk index variables of ASA score, wound class, duration of operation, and endoscope use, as well as gender and age) were identified by multiple logistic regression analyses with stepwise variable selection. The area under the receiver operating characteristic (ROC) curve resulting from these analyses was used to evaluate the predictive power of logistic regression models.Results:For most procedures, at least two of the three variables contributing to the NNIS System risk index were shown to be independent risk factors (appendectomy, knee arthroscopy, cholecystectomy, colon surgery, herniorrhaphy, hip prosthesis, knee prosthesis, and vascular surgery). The predictive power of logistic regression models (including age and gender, when appropriate) was low (between 0.55 and 0.71) and for most procedures only slightly better than that of the NNIS System risk index.Conclusion:Without the inclusion of additional procedure-specific variables, logistic regression models do not improve the comparison of SSI rates from various hospitals.

Abstract:

In medical robotics applications it is often advantageous for a robot to be directly mounted on or supported by the body of the patient during a medical procedure or examination. Whereas early medical robot systems were generally manipulator arms with a large base resting on the floor or mounted to the table next to the patient, several more recently developed systems rest directly on the patient. Body-supported medical robots can be designed to be much more compact and lightweight, leading to improved accuracy and safety and reduced cost, and are easier to set up and use in the operating room environment compared to conventional robot manipulator arms. Five examples of body-supported surgical robots are surveyed in this paper: The ARTHROBOT for total hip arthroplasty, PRAXITELES for knee arthroplasty, MARS for spinal pedicle screw placement and drill guiding, TER for remote ultrasound examinations, and LER for endoscope positioning in minimally invasive surgery.

Abstract:

Abstract Introduction Although stress ulcer disease related to burn injury was noted previously, it was the report of a series of 10 cases by Curling which lent the name to the finding. Occurrence of the disease has been attributed to the stress factors of hemodynamic instability with resultant decrease in defense factors of the gastroduodenal epithelium noted as patients began to survive massive burns. At one time, the incidence was reported as high as 23% of hospitalized burn patients. However, with advances in supportive care and antacid therapy, some have wondered if Curlings ulcers may have become extinct. Methods We report the case of a 21-year-old male admitted after MVC with 53% TBSA burn (32% full-thickness) and multiple blunt trauma injuries. Early in his course he underwent splenectomy, small bowel resection, right hemicolectomy, and ORIF of an unstable lumbar fracture, and below-knee amputation. He underwent staged excision and grafting of burn wounds and had been autografted with exception of about 11%TBSA of the left lower extremity (wound controlled with allograft). On hospital day 38, the patient was noted to have melanotic colostomy output with a concomitant drop in hemoglobin level from 7.6 g/dl to 3.5 g/dl. Results The gastroenterology service was consulted, and they performed upper endoscopy on hospital day 39. A large amount of clotted blood was seen in the stomach, but the source of bleeding was not visualized. Subsequent endoscopy the following day showed an erosion of gastric mucosa in the gastric fundus consistent with ulcer, on which two clips were placed. The patient’s stool was tested for H. pylori antigen and the test was negative. The patient continued on a proton pump inhibitor, non-steroidal anti-inflammatory drugs were held, and his hemoglobin stabilized and melanotic ostomy output resolved. Conclusions Antacid therapy, H2-blockers, and proton pump inhibitors have historically been used in cases of large burns. However, in the care of other critically ill patients the association of this therapy with ventilator associated pneumonias has lead to new scrutiny. In addition, a renewed emphasis on multimodal pain management may be introducing a bias towards an increase in so-called aggressive factors, namely NSAIDS administered over longer periods. Advances in critical care of burn patients have made Curling’s ulcers rare, but not extinct.

Abstract:

Introduction. Bloom syndrome (BS) is an inherited disorder due to mutation inBLMgene. The diagnosis of BS should be considered in patients with growth retardation of prenatal onset, a photosensitive rash in a butterfly distribution over the cheeks, and an increased risk of cancer at an early age. Clinical manifestations also include short stature, dolichocephaly, prominent ears, micrognathia, malar hypoplasia and a high-pitched voice, immunodeficiency, type II diabetes, and hypogonadism associated with male infertility and female subfertility. The aim of this report is to describe case of patient with BS who developed adenocarcinoma of the cecum, successfully treated by right colectomy.Case Report. A 40-year-old man underwent colonoscopy to investigate the cause of his diarrhea, weight loss, and anemia. The patient knew that he was a carrier of BS diagnosed at young age. The colonoscopy showed an expansive and vegetating mass with 5.5 cm in diameter, located within the ascending colon. Histopathological analysis of tissue fragments collected during colonoscopy confirmed the presence of tubular adenocarcinoma, and he was referred for an oncological right colectomy. The procedure was performed without complications, and the patient was discharged on the fifth postoperative day. Histopathological examination of the surgical specimen confirmed the presence of a grade II tubular adenocarcinoma (stage IIA). The patient is currently well five years after surgery, without clinical or endoscopic signs of relapse in a multidisciplinary approach for the monitoring of comorbidities related to BS.Conclusion. Despite the development of colorectal cancer to be, a possibility rarely described the present case shows the need for early screening for colorectal cancer in all patients affected by BS.

Abstract:

Abstract Introduction Venous thromboembolism (VTE) occurs in up to 25% of patients undergoing total hip (THA) or knee arthroplasty (TKA) without the use of prophylactic anticoagulation. Low molecular weight heparins (LMWH) are the standard agents for preventing VTE in this setting. In recent years, rivaroxaban, apixaban and dabigatran have been approved for this indication and, although results from randomized trials suggest that they are non-inferior and potentially superior to LMWH, information regarding outcomes in routine use is lacking. Objectives To evaluate the safety and efficacy of rivaroxaban for the prevention of VTE in patients undergoing THR or TKR in routine practice. Methods We conducted a population-based retrospective cohort study using linked healthcare databases in Ontario, Canada, including information on hospital discharge, emergency room visits, medication use, demographics and physician billing. In Ontario older patients have universal drug coverage and thus we included patients aged 66 years or older who received an outpatient prescription for a LMWH, (including dalteparin, tinzaparin and enoxaparin) or rivaroxaban after discharge from THR or TKR between 2002 and 2012 across 121 hospitals. Patients were excluded if they had other indications for anticoagulation. Primary efficacy and safety outcomes in the 30 days after surgery were the occurrence of an Emergency Room visit or hospitalization with a VTE (either deep vein thrombosis or pulmonary embolism) or a hospitalization with non traumatic major hemorrhage, respectively. Secondary outcomes included the previous 2 endpoints at 90 days as well as hospitalization for digestive system endoscopy (a proxy for gastrointestinal hemorrhage) and all cause mortality, both at 30 and 90 days after surgery. Unadjusted and adjusted odds ratios with 95% confidence intervals (CI) were obtained using logistic regression and reported as relative risks (RR) (appropriate given the incidence observed). Results The cohort included 24,321 patients and there was no significant difference on over 35 baseline characteristics between the LMWH (n=11,471) and rivaroxaban (n=12,850) groups. The median age for both groups was 73 years, 14,366 patients were women (59.1%) and 8,612 patients (35.4%) underwent THR. Anticoagulants were prescribed for a median of 14 days after discharge (interquartile range 10 to 21). The main results are shown in the table. Results were consistent in multiple additional analyses accounting for years rivaroxaban was approved in provincial formulary, adjusting for potential confounders, secular trends, individual LMWH, prescriber characteristics, and for subgroup analyses examining THR and TKR separately. Conclusions In this routine practice population-based study, the use of rivaroxaban compared to LMWH was associated with a lower risk of VTE without an increase in bleeding events.

Abstract:

Abstract BAX 855 is a pegylated full-length recombinant factor VIII (PEG rFVIII) built on rFVIII (ADVATE) with an extended half-life and is intended for prophylaxis and the treatment of bleeding in patients with hemophilia A.1 This phase 3 surgery study is evaluating the efficacy and safety of BAX 855 for the perioperative control of hemostasis. Patients' informed consent and appropriate ethics committee approvals were obtained. Elective procedures were prospectively classified (major or minor) by the investigator/surgeon and major emergency surgeries were excluded. The target trough FVIII levels for major and minor surgeries were to be ≥80% and 30-60%, respectively. Each patient's pharmacokinetic (PK) profile was used to guide the BAX 855 dose and infusion frequency. BAX 855 PK were consistent with previous PK assessments with terminal half-life ranging from 8.81 to 18.06 hours for the 15 patients in this study. In this interim analysis, 15 male previously treated patients (PTPs) ranging from 19 to 52 years of age have undergone 15 procedures in 7 countries. Individual procedure profiles are compiled to evaluate the control of hemostasis for BAX 855. There were 11 major procedures: 6 orthopedic (3 knee replacements, 2 arthroscopic synovectomies, 1 elbow cyst extirpation) and 5 non-orthopedic procedures (3 dental [root canals for 2 teeth, 2 extractions of ≥4 teeth, 1 radicular cyst removal], 1 cardiovascular [mediport placement], 1 abdominal [gastric band insertion]). The 4 minor surgeries comprised 1 synoviorthesis, 1 dental, 1 dermatological and 1 endoscopy (radiosynovectomy) procedure. Efficacy was evaluated by the surgeon or investigator's rating of hemostatic control using 4-point scale which was based on blood loss and by comparing actual blood loss with predicted blood loss which was specified by the surgeon for non-hemophilia patients prior to the procedure. For all procedures, the hemostatic control of BAX 855 was rated "excellent" for the intraoperative (during the procedure), postoperative (24 hours after completion of the procedure), and perioperative (from start of the procedure until discharge or day 14) periods, except for 1 minor dental procedure in which postoperative efficacy was rated "good" and 1 minor procedure in which a postoperative rating was not provided (for both of these procedures intra- and perioperative ratings were "excellent"). Actual blood loss (ABL) for the intraoperative and postoperative periods were compared with predicted average and maximum values. Intraoperative ABL for all minor and major procedures was less than or equal to predicted averages and maximums, except for 1 minor procedure in which the ABL was greater than the predicted average and maximum and 1 major procedure which did not have ABL recorded. Postoperative ABL was less than or equal to predicted averages and maximums for 4/4 minor procedures and 5 major procedures. For 4 major procedures, postoperative ABL was greater than or equal to predicted average, but less than predicted maximums. For the remaining major procedure (synovectomy with general anesthesia) with reported ABL, postoperative ABL was greater than the predicted the average and maximum - the efficacy assessments at all periods for this procedure were considered "excellent". These results demonstrate the efficacy of BAX 855 for the perioperative control of hemostasis in patients with severe hemophilia A. 1 Konkle BA, Stasyshyn O, Chowdary P et al.

Abstract:

Background: Sphenoid sinus (SS) is separated by a septum with various position, therefore sizes of two sinus cavities are variable [2]. In addition, sphenoid sinus differs in pneumatization type, ranging from its absence to extensive forms.Knowledge of the linear size and shape of the skull, the structure of the sphenoid sinus and its interconnection with nearby structures will help to avoid complications when performing surgical endoscopic interventions in the chiasmal-sellar region. Currently, the transsphenoid approach is the most optimal in neurosurgery for intracellar and cranial pathologies treatment. Due to proximity and anatomical interconnection of sphenoid sinus with other anatomical structures, such as anterior knees of intracavernous segments of internal carotid artery (ICA), optic nerve (ON), there is a high risk of complications during surgery [1,2,3,4]. Purpose: Features of skull craniometric parameters, the type sphenoid sinus pneumatization, and its practical value in various ON and ICA positions. Methods: The retrospective research, using magnetic resonance imaging (MRI) scans of head, included 1111 people, with 410 males and 701 females out of them but the scope of the article is limited to 93 of them, including 34 males (37%) and 59 females (63%) aged from 20 to 71 years. The research design complies with the Helsinki Declaration’s provisions and was approved by the Local Ethics Committee of the West Kazakhstan Medical University named after Marat Ospanov №50 from January 17, 2020. The average age of males was 41.6 (20 – 71 years), and for females was 41.7 (20 – 66 years). Inclusion criteria were as the following: 1) age range from 20 to 71 years, 2) patients living in Aktobe region, 3) patients sent for examination with pituitary (hypophysis) pathology, 5) patients referred with CSR vascular pathology, 6) patients referred for verification of CSR pathology diagnosis. Exclusion criteria were as the following: 1) patients with skull bones fractures, 2) patients after skull trepanation, 3) patients having orthodontic and orthognathic research at examination time, 4) patients with congenital skull malformations, having gross skull deformation, 5) patients with brain tumors and hemorrhages with obvious CSR compression at examination time, 6) pregnancy, lactation, long-term use of hormonal drugs by persons of both gender. With the RadiAnt Dicom Viewer 5.5.1 program measured craniological indices: crosslongitudinal skull index, degree of pneumatization of the sphenoidal sinus; protrusion and/or gaping of internal carotid artery canal and optic nerve.Allstatistical analyses were performed using Statistica 8.0. Results: The data we obtained show that the vast majority of older males (60-80 years old) had mesocrane skull shape, in contrast to females, among whom the frequency of brachycrane skull shape prevails. Among 20-40 years aged males, the highest percentage falls on mesocrane skull form, while in females the frequencies of mesocrane and brachycrane skull forms are relatively the same. In males and females with ages of 40-60 years, mesocrane and brachycranean skull forms are almost half of the total number of cases. An interesting fact was that dolichocranous skull shape is absolutely not found in both males and females of 40-80 years old age. The skull structure distribution by gender. Based on the sphenoid sinus types classification by Ossama & Guldner, our research revealed that there is no Conchal type (type I) in both genders. In 20-40 age, type III prevailed among males, while type IV has a maximum among females. Types III and IV predominated among males and females of 40-60 years old age. In 60-80 years category, type III prevails among females, while males have two times less. Type II is absent among 40-60 aged males and 60-80 aged females. As per the research of anatomical structures close to SS, it was found that ON and ICA canals form protrusions on the inner surface of the sphenoid sinus sidewall. The protrusion degree was ranged from a slight depression on the lateral wall to a complete "immersion" of canals into the sinus. No protrusion of ON and ICA canals were found in 60-80 years old males in 80% of cases, while complete absence of protrusion was shown in case of the same age females. However, protrusion of only the ICA canal occurs in 60% of cases with over 60 years old age females, while the same was in only 20% with the same age males. There was no case of ON canal protrusion in males, but ON canal gave a protrusion in sphenoid sinus wall in 49% of 20-40 years old females. ON and ICA canals protrusion in 20-60 years old males was found in about 30%, and the same protrusion was found in 60-80 years old females in 40%. Conclusions: This study is aimed at identifying the features of structure of the sphenoidal sinus, focusing on the absence of a dolichocrane type of skull among the population, on the clear distinction between men and women by the type of skull structure and the features of pneumatization of the sphenoidal sinus. The presellar type of sphenoidal sinus has a virtually low adherence to changes in sinus canals in types II and IV. Thus, careful planning of trans-sphenoid access to the sella is possible with modern imaging methods. Different anatomical variations can be detected so that problems can be predicted to be assessable. In order to avoid morbid consequences during surgery, it is imperative that clinicians determine the location and extent of sphenoid sinus walls and its relation to adjacent vital structures whenever trans-sphenoid pituitary surgery is expected. The few surgical tips related to sphenoid sinus anatomical configuration are important to keep in mind during such an approach.

Abstract:

Arthroscopy is an innovative method used in the field of orthopedics to enter the joint by endoscopic method, to see, to take photos and to perform operations. Currently, arthroscopy functions in practice as diagnostic arthroscopy and arthroscopic surgery. The technological development and widespread use of arthroscopy, which is currently very advanced, has taken time. I tried to contribute to the initiation and development of arthroscopy studies in Turkey when I was working in Ege University Faculty of Medicine Orthopedics and Traumatology Clinic and in the “later period” of my professional life. Our aim is to briefly touch on the development of arthroscopy in the world and in Turkey from yesterday up to today, and also to share the information we have witnessed about arthroscopy in Turkey, emphasizing its importance especially in terms of patient and public health

Abstract:

Bleeding duodenal diverticulum is an infrequent pathology in need of emergency treatment due to its high mortality. We present the clinical case of a 72-year-old patient with multiple comorbidities, who was admitted with upper gastrointestinal bleeding, abdominal pain and hemodynamic instability. Once hemodynamic stability was achieved, upper digestive endoscopy was performed, showing duodenal diverticulum in the upper knee with bleeding in the fundus, performing hemostatic control. CT was requested: at the level of the upper duodenal knee, wide base diverticulum. Surgery was scheduled for the high risk of new bleeding. In surgery, cholecystectomy and diverticulectomy were performed laparoscopically with mechanical suture. Anatomopathological report: duodenal wall with parietal thinning of the duodenum, suggestive of diverticulum by pulsion. The discharge was granted with radiological control on the 3rd postoperative day. The aim of this case is to show the importance of endoscopic resolution of urgency and subsequent laparoscopic management in a patient with important risk factors, evidencing the short hospital stay without postoperative complications.

Abstract:

Meniscal injuries are a common challenge in orthopaedic surgery. Depending on their location and the patient’s age and functional needs, they can be treated either conservatively or surgically. A surgical approach can consist of arthroscopic meniscectomy or meniscal suture. The latter is the treatment of choice in case of lesions involving the red-red or red-white areas of the meniscus, especially for young high-demanding patients. We report here our experience with the repair of longitudinal meniscal tears using the all-inside technique with the Fast-Fix™ 360 Meniscal Repair System (Smith & Nephew Endoscopy, Andover, MA). We retrospectively evaluated 20 consecutive cases of longitudinal meniscal tears. In 4 cases, concomitant ACL rupture was diagnosed and treated alongside the meniscal repair. All patients underwent periodic clinical evaluations. At the latest check-up, their functional outcomes were rated according to the Tegner-Lysholm Knee and KOOS scoring scales. The mean Tegner-Lysholm Knee score was 84.85 (44-100) and the mean KOOS score was 88.58. No failure or major complications were observed. Furthermore, a negative statistical association was observed between age at surgery and the post-operative Tegner-Lysholm Knee score (coef. = -1.01189 [-1.942073,-0.0817063], p = 0.035). This relation, independent of gender, meniscus involved, eventual associated ACL reconstruction, and chondral injury, suggests that functional outcomes worsen with increasing patient age. Our results suggest that the arthroscopic all-inside suture is both safe and effective in cases of longitudinal meniscal tear, considering the good post-operative functionality and low rates of local complications and surgical failures.

Abstract:

Introduction: Primary tumors arising from the peripheral nerves are a rare occurrence. In 90% they are benign, although in a small percentage there is a risk of neoplastic transformation. Schwannomas and neurofibromas are the leading etiologies. They are commonly found in the neck and large nerves of limbs and arms, with a preference for regions of the elbow, wrist, and knee. The most vulnerable group of patients are people aged 20 to 50 years. The occurrence of this type of tumors in children is sporadic, especially if the tumor includes the brachial plexus. Materials and Methods: The clinical case of a neurinoma in a supraclavicular region, affecting a 12-year-old girl. After a detailed diagnosis, the tumor finally came to be a schwannoma of a brachial plexus. Discussion: Brachial plexus schwannoma is a rare find, although it should be considered in the differential diagnosis. A detailed search for signs of neurofibromatosis (von Recklinghausen's disease) should also be performed. Initial diagnostic imaging of cervical mass includes mainly MRI, thanks to which the surgeon can suspend the tumor of nervous origin, assess the vicinity of important nerves, vessels, and cervical spinal cord, as well as qualify for the surgery. Surgical treatment should be carried out after assessing the benefits and risks associated with the procedure, including irreversible damage to the brachial plexus. To maintain safety during the operation, the use of microsurgical instruments, microscopes or endoscopes should be considered by an experienced surgeon. Preserving nerve continuity is the essential goal of the treatment, especially in young, and active patients. Finally, the long-term observation is necessary for the assessment of potential tumor neoplastic transformation, nerve function of the brachial plexus and possible symptoms of neurofibromatosis.
