Abstract (sommario):

SummaryTo reduce postoperative complications due to pelvic canal narrowing following triple pelvic osteotomy, it is important to minimize the length of the pubic remnant on the acetabular segment. Three different techniques for performing the pubic osteotomy were compared: a lateral wire saw technique, a lateral osteotome technique and a ventral osteotome ostectomy technique. The lateral wire saw and ventral ostectomy techniques resulted in significantly shorter pubic remnants than the lateral osteotome technique. The osteotomies performed with the wire saw were more accurate and precise than those performed with the osteotome. The lateral wire saw technique is a practical alternative to the ventral ostectomy technique for performing the pubic osteotomy.A comparison of three different pubic osteotomy techniques for the triple pelvic osteotomy showed that minimal pubic remnants can be achieved with either the lateral wire saw or ventral ostectomy technique. Osteotomies made by the wire saw were more accurate and precise than those made by the osteotome.

Abstract (sommario):

Damage to the lacrimal drainage system is a potentially complicating factor in rhinoplasty utilizing lateral osteotomies. The authors present data from osteotomies performed on a series of fresh cadavers. Following completion of the osteotomies, the lacrimal sac and nasal lacrimal ducts were Identified and cannulated. Soft tissue was dissected to demonstrate the osteotomy site. The specimen was inspected to delineate involvement (if any) of the lacrimal duct or sac. The proximity of the osteotomy site to the lacrimal drainage apparatus components was measured in each specimen. Various parameters were observed, including the effect of curved vs. straight osteotomes, guarded vs. unguarded osteotomes, and the effect of various widths of osteotomes. Likewise, the degree of risk to the lacrimal system was evaluated, and the technique of the novice and resident surgeon was compared to that of the experienced rhinoplastic surgeon. A low, curved osteotomy, performed with a sharp osteotome without subperiosteal tunnels, provides the safest maneuver. Lateral osteotomies, properly performed, prove to be an unusual cause of lacrimal drainage dysfunction.

Abstract (sommario):

Proper selection of an osteotome for nasal osteotomy is important for minimizing soft tissue trauma. Radiographic analysis of the facial bony lateral wall thickness was performed to suggest a guideline for an appropriate osteotome size for Asians. Facial bone computed tomography (CT) of 100 patients (50 male, 50 female) were studied. The thickness of the facial bony lateral wall at three points along the track of a lateral osteotomy, and two points along the track of a medial osteotomy and intermediate osteotomy were measured. The average bony thickness along the track of a lateral osteotomy was 2.61 ± 0.66 mm at the low level, 2.75 ± 0.76 mm at the middle level, and 2.72 ± 0.53 mm at the high level in subjects. The average bony thickness along the track of an intermediate osteotomy were 1.26 ± 0.34 mm at the low level, and 1.31 ± 0.32 mm at the high level in the subjects. The average bony thickness along the track of the medial osteotomy were 2.54 ± 0.31 mm at the lowlevel, and 2.77 ± 0.30 mm at the high level in subjects. These results may provide a guideline for choosing an osteotome of appropriate size for the Asian population.

Abstract (sommario):

Rhinoplasty remains one of the most commonly performed aesthetic surgical procedure that demands a meticulous intraoperative precision as well as maximum precaution and control. Nasal osteotomy is a key component to shape the bony vault in aesthetic rhinoplasty, but it is also the so versatile, dangerous, and difficult to learn. The present study aims to evaluate the usefulness of our locator instrument for beginners which is called transilluminating osteotome. The use of transilluminating osteotome instead of guided lateral nasal osteotome is a reliable instrument since it facilitates the localization of osteotome and osteotomy line beneath the soft tissue with a limited damage to the surrounding soft tissues.

Abstract (sommario):

Osteotomy is a common step in oncological, reconstructive, and trauma surgery. Drilling and elevated temperature during osteotomy produce thermal osteonecrosis. Heat and associated mechanical damage during osteotomy can impair bone healing, with consequent failure of fracture fixation or dental implants. Several ex vivo studies on animal bone were recently focused on heating production during osteotomy with conventional drill and piezoelectric devices, particularly in endosseous dental implant sites. The current literature on bone drilling and osteotomic surface analysis is here reviewed and the dynamics of bone healing after osteotomy with traditional and piezoelectric devices are discussed. Moreover, the methodologies involved in the experimental osteotomy and clinical studies are compared, focusing on ex vivo and in vivo findings.

Abstract (sommario):

Summary Objectives: To compare the results of femoral head and neck excision (FHNE) ostectomy performed by two novice veterinarians using an osteotome and mallet or microsagittal saw. Methods: In this ex vivo cadaveric study, hindlimbs of eight canine cadavers were randomized to FHNE with osteotome or micro sagittal saw as performed by two recently graduated veterinarians. The hindimbs were imaged by computed tomography (CT) before and after the osteotomy. Post FHNE CT images were evaluated by a board certified radiologist blinded to the ostectomy technique for assessment of the number of bone fragments, fissures, smoothness of osteotomy margination, and volume of residual fe-moral neck. Results: Femoral head and neck excision performed with the osteotome produced more peri-ostectomy bone fragments, cortical fissures, irregular margins, and residual femoral neck volume, compared with osteotomy using a saw. Clinical relevance: Compared to FHNE performed with a sagittal saw, osteotome FHNE resulted in a greater bone trauma and residual neck bone volume, which would require post-ostectomy modification in a clinical setting.

Abstract (sommario):

Background: There have been reported about impacted tooth[1,2,3], but a very few literature about extraction technique using bone osteotomy. Bone osteotome is routinely used in various oral surgeries. We describe a technique of a unique bone osteotome technique for extraction of palatally inclinated maxillary impacted tooth. Methods: We occasionally encounter the patient with tooth crown of impacted tooth inclinated from the buccal site toward the palatal site. When the use of an elevator and forceps is difficult due to the palatal tilted and interference of neighboring teeth, tooth extraction is a challenge.Using this osteotome from the buccal site causes the canine to easily rise out of the socket in the palatal direction. Results and Conclusion: This bone osteotome technique for extraction of palatally inclinated maxillary impacted tooth was very useful and convenient.This is because the impacted canine can be removed with a bone osteotome, a minimally invasive surgical instrument. No appreciable disadvantages are noted with this bone osteotomy. Keywords: Unerupted Tooth; Impacted Canine; Supernumerary Teeth

Abstract (sommario):

ABSTRACT Trochanteric osteotomy, the most extensile approach, is a valuable tool for difficult primary and revision total hip arthroplasties (THAs). Extended trochanteric osteotomy (ETO) is helpful in revision and extraction of well-fixed cemented as well as uncemented fremoral components, facilitates in cement extraction, and also in enhancing acetabular exposure. Tradional posterolateral ETO is initiated at the posterior aspect of the femur. We describe a modification of ETO by an anterolateral approach. The advantage of this approach is that as it preserves an intact musculo-osseo-muscular sleeve comprising of gluteus medius and minimus, greater trochanter, and vastus lateralis it allows physiological reconstruction of hip's soft tissue envelope and thus prevents proximal migration, nonunion of the osteotomy, and abductor lurch, which are the commonest complications associated with an ETO. Anterolateral exposure of hip joint and anterior fibers of gluteus medius, minimus, and capsule reflected as cuff and limbs of osteotomy are marked, and after completing the osteotomy with the help of osteotomes passed from posterior to anterior, the fragment is hooked open on its anterior muscular hinge. Osteotomy is fixed with the help of three to four cerclage wires depending on length of osteotomy. Full-weight bearing and abduction against gravity are only allowed after confirming radiological union of the osteotomy. How to cite this article Kacker S, Singh C, Marya SKS.

Abstract (sommario):

The result of 27 Chiari pelvic osteotomy were analyzed to determine the efficacy of the operation in the treatment of subluxated and/or painful dysplastic hips. The length of follow-up ranged from 2 to 14 years. Eighteen patients had had developmental dysplasia of the hip; four sequelae of the septic hip; two, cerebral palsy and one had had poliomyelitis. The osteotomy can be done by power saw and osteotome. A large threaded K-wire was used for internal fixation. Bone graft was necessary even with the displacement of more than 50%. The overall result were: 12, excellent; 8, good; 5, fair; and 2 poor. In 11 patients, the osteotomy had to be displaced more than 50% to provide good coverage of the femoral head. There were no major complications such as sciatic nerve injury or delayed union. This procedure is most suited for the patient with painful hip dysplasia in whom a concentric reduction is not possible.

Abstract (sommario):

A FEA-based methodology was developed in order to predict the wear status of an osteotome (surgical instrument) during its use in a lateral nasal bone osteotomy considering its fatigue strength. The latter parameter was determined by appropriate FEM-evaluation of the perpendicular impact test results. For the simulation of the surgical procedure, two scenarios were examined: (i) when utilizing a brand new osteotome and (ii) when utilizing an already used osteotome characterized by decreased fatigue strength. The actual nasal bone geometry used in the FEA model was obtained from a high-resolution, maxillofacial, computed tomography (CT) scan of a single patient. In both cases examined, depiction of fracture patterns for the osteotome and the nasal bone were obtained. The wear of a new osteotome and an already used osteotome was also calculated and compared. The developed von Mises stresses in both the osteotome and nasal bone were depicted. The proposed methodology allowed an accurate prediction of the critical number of impacts that the osteotome can receive during the lateral nasal osteotomy which is followed in all rhinoplasties. Based on the developed methodology, a preventive replacement of the osteotome before its extensive fracture can be determined, thereby minimizing the risk of postoperative complications.

Abstract (sommario):

Background: Tibial tubercle osteotomy and distal realignment allows for adjustment to the patellofemoral articulation in order to improve patellar tracking and redistribute patellar contract pressures. Indications: A healthy, active 39-year-old woman status post right knee tibial tubercle osteotomy presented with >2 years of patellar instability symptoms in the left knee. Imaging revealed a tibial tubercle to trochlear groove (TT-TG) distance of 21 mm and patellar tendon lateral trochlear ridge (PT-LTR) distance of 14 mm. Technique Description: After knee arthroscopy is performed, an open incision is made along the inferomedial patellar tendon. Two pilot holes are created before a sagittal saw is used to make the tibial tubercle osteotomy, before completing it with an osteotome. Anteromedialization and/or distalization of the osteotomy is performed relative to templated values in order to improve patellar articulation. After correction, 3 bicortical screws are placed to achieve stable fixation. Results: There were no immediate complications following surgery. Surgical management led to improvement of the patient’s patellofemoral pain, which allowed return to prior baseline level of function. Discussion/Conclusion: The preferred technique for an anteromedialzing tibial tubercle osteotomy is presented. An anteromedializing tibial tubercle osteotomy is an effective surgical option for patients with evidence of patellar maltracking or central or lateral patellar chondromalacia whom have failed conservative management. This case demonstrates the efficacy of an anteromedializing tibial tubercle osteotomy to provide pain relief by improving patellar tracking and offloading patellar contact pressures on areas of prominent chondral wear.

Abstract (sommario):

Abstract The sinus elevation procedure is a predictable technique to allow for placement of dental implants in the posterior maxilla when the height of the alveolar ridge is limited. The sinus elevation can be performed by various techniques. In the crestal approach, bone graft is utilized to hydraulically elevate the sinus membrane through an osteotomy prepared in the alveolar crest. The implant can be placed either immediately or at a later surgery. This is a case report of an oroantral communication that developed as a complication to a sinus elevation surgery performed with the crestal approach. A 54-year-old female patient presented for dental implant treatment. The patient reported sleep apnea and smoking. Full-thickness flap was reflected in the posterior maxilla and using trephines, an osteotomy was prepared, 1 mm short of the sinus. The trephined core of bone was pushed into the sinus using osteotomes. Particulate bone graft was introduced through the osteotomy to elevate the sinus membrane, and a collagen membrane was used over the bone graft. Six days after surgery, the patient returned to the clinic with an oroantral communication. The patient reported that she was using a positive-pressure breathing mask at night because of sleep apnea. A flap was extended to the tuberosity area and was rotated palatally to achieve closure. The use of the pressure breathing mask was discontinued. The oroantral communication was successfully closed. Relatively few complications have been reported using the osteotome sinus elevation technique. The use of a positive pressure mask may have complicated a sinus elevation surgery. Other factors that may have contributed to this complication include smoking and delayed healing of the area.

Abstract (sommario):

Category: Midfoot/Forefoot Introduction/Purpose: Second metatarsal shortening osteotomy is frequently used in the treatment of metatarsalgia and aims to decrease metatarsophalangeal joint and plantar pressures. Although various proximal, midshaft, and distal metatarsal osteotomy methods have been described for surgical treatment of metatarsalgia, to our knowledge no studies quantitatively compared their resulting geometric corrections. The purpose of our study was to investigate how much each osteotomy variation changed the length of the metatarsal as well as the height and relative location of the metatarsal head (MH) itself. Methods: Following Institutional Review Board approval, three-dimensional computer models of second metatarsals of 5 deidentified clinic patients were extracted from CT scans using Mimics software. Fixed points were plotted on the printed models and a 3D coordinate digitizing arm (Microscribe) was used for precisely determining the 3D (x-y-z) coordinates of each point before and after the osteotomies. Six variations of second metatarsal osteotomies were performed using microsagittal saw and fixed using a 2.4 mm cannulated screw. The following osteotomy variations were performed with 3 and 5 mm translation or wedge resection for each patient model: (1) Classic Weil osteotomy performed at 15° and 25° to the plantar surface; (2) Classic Weil osteotomy performed at 15° and 25° using a double saw blade technique; (3) Classic Weil osteotomy performed at 25° and then a parallel block of 3 or 5 mm was removed; (4) Distal closing wedge osteotomy of the MH at 25°; (5) Proximal closing wedge osteotomy of the MH made at 45° removing a 3 and 5 mm wedge; (6) 45 degree oblique, midshaft, metatarsal osteotomy with 3 and 5 mm of translation. The change in the length of the metatarsal, and vertical and medio-lateral translation of the metatarsal head was calculated then normalized by the osteotomy translation distance. A general linear model with correlated errors and Bonferroni correction was used to assess differences between osteotomies. Results: The maximum metatarsal length shortening per millimeter translation was observed in osteotomy 3- 5 mm block (2.6 mm STD=2.1), while osteotomy 1- 15° caused the least (1.1 mm STD=0.6). Maximum dorsiflexion of the MH occurred with osteotomy 5- 5 mm wedge, 13.2 mm (STD= 4.9 mm) and minimum with osteotomy1- 25°, 0.5 mm (STD= 1.4 mm). No MH plantarflexion was noted with any of the osteotomies. The oblique midshaft osteotomies caused lateral translation of the metatarsal head significantly different from the controls (P <0.05) although not statistically different from one another (2.4 mm vs 4.3 mm). Conclusion: Discussion: Our data shows maximal change in length/millimeter translation by performing a classic Weil osteotomy at 25° to the plantar surface of the foot, 5 mm block resection and then translating 4 mm. This osteotomy also caused the most effective dorsal translation of the MH, thereby making it the most effective osteotomy in terms of affecting both length and MH vertical orientation. Should dorsiflexion of the MH be the surgeon’s only goal, then the proximal closing wedge osteotomy had the greatest impact while minimally changing overall length. With this knowledge, surgeons can tailor operations based on the direction and degree of correction needed to be achieved.

Abstract (sommario):

Rotational malreduction is a potential complication of intramedullary nailing for tibial shaft fractures. We experienced a symptomatic case of a 24° externally rotated malunion that we treated with minimally invasive corrective osteotomy. A 49-year-old man sustained a tibial shaft spiral fracture with a fibula fracture. He had been initially treated elsewhere with a reamed statically locked intramedullary nail. Bone union had been obtained, but he complained of asymmetry of his legs, difficulty walking and running, and the inability to ride a bicycle. We decided to perform corrective osteotomy in a minimally invasive fashion. After a 1 cm incision was made at the original fracture site, osteotomy for the affected tibia was performed with an osteotome after multiple efforts at drilling around the nail with the aim of retaining it. Fibula osteotomy was also performed at the same level. Two Kirschner wires that created an affected rotational angle between the fragments were inserted as a guide for correction. The distal locking screws were removed. Correct rotation was regained by matching the two wires in a straight line. Finally, the distal locking screws were inserted into new holes. The patient obtained bony union and has returned to his preinjury activities with no symptoms.

Abstract (sommario):

Background: Meniscal allograft transplantation improves functional and patient-reported outcomes in patients with meniscal deficiency without significant osteoarthritis. In addition, it is known that valgus malalignment of the knee can lead to meniscal and chondral damage, and surgery is often indicated to restore the mechanical axis and slow progression of osteoarthritis. Indications: Indications for this procedure include patients with symptomatic lateral meniscal deficiency with associated valgus deformity of the knee. Patient’s age must be less than 50 years, body mass index less than 35 kg/m2, meniscal deficiency, and ipsilateral pain with or without swelling. Ligament tears, focal cartilage loss, and malalignment are not contraindications if also corrected. Technique Description: We begin by removing the remaining lateral meniscus, taking care to leave a small peripheral rim of meniscus. A transpatellar tendon arthrotomy is performed, and the meniscal allograft is passed through the arthrotomy and into the knee. An inside-out repair is performed using vertical mattress sutures. The sutures are tightened and tied with the knee at 30° to 40° of flexion. The distal femoral osteotomy is then performed. An approach is made to the lateral femur, where initial guidewires are placed using fluoroscopic guidance. The initial saw cut is made about 75% of the way across the femur, and an osteotome is used to complete the osteotomy. Care is taken to preserve the far medial cortex. An adjustable wedge osteotome is placed to open the lateral cortex in accordance with the preoperative template. The cortical wedge is fashioned using the tibial allograft from the meniscal transplant and is placed into the osteotomy. The osteotomy is secured using a locking plate with locking screws, and this is confirmed in safe position using fluoroscopy prior to the conclusion of the case. Results: Patients will have effective deformity correction and alleviation of pain. Many patients can return to sport without restrictions following appropriate rehabhilitation. Conclusion: Lateral meniscal allograft transplantation with distal femoral opening wedge osteotomy is an effective treatment for symptomatic lateral meniscal insufficiency with associated valgus deformity of the knee in patients without osteoarthritis.

Abstract (sommario):

Our aim for this study was to evaluate and compare the clinical outcomes in patients who underwent lateral osteotomy with a Piezosurgery device or a conventional osteotome in open-technique rhinoplasty. This cohort trial involved 65 patients (36 women and 29 men; average age: 23.6 ± 5.71 yr) who underwent surgery between May 2015 and January 2016. Piezo-surgery was used for lateral osteotomy in 32 patients, whereas 33 patients underwent conventional external osteotomy. These 2 groups were compared for duration of surgery, perioperative bleeding, postoperative edema, ecchymosis, pain, and patient satisfaction on the first and seventh postoperative days. The Piezosurgery group revealed significantly more favorable outcomes in terms of edema, ecchymosis, and hemorrhage on the first day postoperatively (p < 0.001 for all). Similarly, edema (p = 0.005) and ecchymosis (p < 0.001) on the seventh postoperative day also were better in the Piezosurgery group. Hemorrhage was similar in both groups on the seventh postoperative day (p = 0.67). The Piezosurgery group not only experienced less pain on the first postoperative day (p < 0.001), but these patients also were more satisfied with their results on both the first and seventh postoperative days. Results of the present study imply that Piezosurgery may be a promising, safe, and effective method for lateral osteotomy, a critical step in rhinoplasty. The time interval necessary for the learning curve is counteracted by the comfort and satisfaction of both patients and surgeons.

Abstract (sommario):

One hundred fifty two patients underwent lengthening of 174 femurs with fully implanted guided device inwhich patients muscular energy was used as a source of energy. Dissection of bone from the side of bone marrow canal was carried out by specially eleborated osteotome which provided transverse oblique, oblique transverse, Z-shape strraight and Z-shape oblique osteotomy. Transverse osteotomy was applied in 59 patients (33.9%), oblique - in 70 (40,6%), oblique transverse - in 26 (14.9%) patients. Distraction stage was completed in all patients. In 165 (94.8%) out of 174 cases planned volume lehgethening was achieved. In 150 patients devices were removed. Average rate of distraction was 1.4 0,3 mm/ daily, average duration of distraction was 87 13 days. Good results were achieved in 141 cases (94%), satisfactory - in 7 cases (4.6%), unsatisfactory - in 2 cases (1.4%) out of 150. Complications were observed in 30 (17.2%) out of 174 cases. In 9 cases (5.2%) complications influenced the treatment outcome. Analysis of complications showed that they might be to great extent prevented by accurate observance of the technique of distractor implantation, performance of osteotomy, rate of distraction and rational postoperative management of patient.

Abstract (sommario):

ased on the finite element method, the effect of porous osteotomy block on the biomechanics of surrounding joints in the treatment of flat foot by Evans osteotomy is studied. The finite element method is used to simulate the osteotomy block for Evans osteotomy to correct flatfoot. The effect of Evans osteotomy on the foot force line is analyzed from the biomechanical point of view. The osteotomy blocks were divided into solid osteotomy blocks and porous osteotomy blocks, and normal foot and flat foot were used as control groups. The results show that Evans osteotomy can effectively improve the force line of the foot to correct the flat foot. Compared with the solid osteotomy block, the porous osteotomy block can also play a corrective effect and reduce the stress shielding effect when used for Evans osteotomy to correct the flat foot.

Abstract (sommario):

Abstract Edentulous ridges in the posterior maxilla are often compromised by reduced bone volume. This anatomic condition often limits dental implant placement of 10 mm in length without prior or simultaneous sinus augmentation. The osteotome technique is an alternative and conservative technique for sinus floor augmentation and immediate implant placement in the posterior region of the maxillary jaw. According to the relevant literature, the osteotome technique appears to be a predictable and safe method for augmenting bone at the sinus floor and to improve bone density and quality of the implant site sufficiently so that immediate loading is possible. A 46-year-old male patient was referred to the authors to replace the single upper premolar with an implant-supported crown restoration without interfering with the integrity and topography of the adjacent gingival tissues. Only one clinical study analyzed minimally invasive implant and sinus lift surgery with immediate loading. In that case report, the osteotomy was widened to its final diameter using a series of incrementally larger twist drills. In our clinical case, a series of incrementally larger diameter osteotomes improved bone density. This simplified treatment modality can make single tooth implant rehabilitation of the atrophic premolar maxilla region more accessible, and immediate loading is facilitated by improved bone density.

Abstract (sommario):

Background and Aim: Spinal osteotomy is a general term for techniques applied to correct spinal deformity. The aims of osteotomy are to create a normal range of spine curvature, pain relief, and to improve quality of life. In the cases where spinal deformities cannot be corrected using instrumentation alone or by facet or ligament release, osteotomy is indicated. In spinal osteotomies, spinal alignment is corrected by removing part of the spinal bone. Osteotomies can be performed as anteroposterior or posterior-only procedures with a greater predilection for posterior-only procedures. Different types of osteotomy are available, including the Smith-Petersen osteotomy (SPO), Ponte osteotomy (PO), pedicle subtraction osteotomy (PSO), corner osteotomy (CO), or bone-disc-bone osteotomy (BDBO), vertebral column decancellation (VCD) and vertebral column resection (VCR). Methods and Materials/Patients: In this narrative study, to provide up-to-date information, we precisely reviewed articles in the osteotomies context. Using the keywords spinal osteotomy, spinal deformity, Smith-Petersen osteotomy (SPO), pedicle subtraction osteotomy (PSO), vertebral column resection (VCR), vertebral column decancellation (VCD), Ponte osteotomy (PO), corner osteotomy (CO), all the relevant articles were retrieved from PubMed, Google Scholar, Medline, and critically reviewed and analyzed. Results: In the spine surgery, osteotomy is performed to correct the deformity in uncorrectable spinal deformity. The suitable type of osteotomy is selected based on the etiology, type, and apex of deformity, surgeon's experience, availability of blood and bleeding control agents, and availability of intensive care. A wider acceptance of posterior-only procedures exists in osteotomy. Conclusion: In spinal deformity surgery, more degrees of correction are needed for better cosmetic results, and for this purpose, spinal osteotomy has a central role. For this reason, all spine surgeons should be familiar with these osteotomy techniques.

Abstract (sommario):

Background: Differences in clinical and radiographic results following total hip arthroplasty between failed wedge and curved varus osteotomy are unclear. Objective: To investigate differences in clinical and radiographic results following total hip arthroplasty in patients who exhibited failed wedge or curved varus osteotomy. Method: We performed 18 total hip arthroplasties after failed femoral varus osteotomy. Hips were divided into two groups: 14 had failed wedge varus osteotomy and four had failed curved varus osteotomy. Average ages at osteotomy and total hip arthroplasty were 27 years old (range, 10-46 years old) and 56 years old (range, 25-74 years old), respectively. The average duration of follow-up monitoring was 72.2 months (range, 54-91 months). Clinical and radiographic evaluations were completed for each group. Results: The Japanese Orthopaedic Association hip score of total hip arthroplasty after failed varus osteotomy significantly improved at the last follow-up in both groups. However, hip score at the last follow-up was significantly higher after failed curved varus osteotomy than after failed wedge varus osteotomy (p<0.01). Four hips that failed wedge varus osteotomy underwent subtrochanteric corrective osteotomy with total hip arthroplasty. Radiographic evaluation showed that three stems for total hip arthroplasty after failed wedge varus osteotomy were inserted in malposition, and all stems in total hip arthroplasty after failed curved varus osteotomy were inserted in the normal position. Conclusion: Surgeons performing femoral varus osteotomy should consider possible future conversion to total hip arthroplasty. Curved varus osteotomy is more suitable than wedge varus osteotomy for future conversion to total hip arthroplasty.

Abstract (sommario):

Between January 2003 and December 2004, 13 patients underwent bilateral resurfacing arthroplasty via a Ganz trochanteric osteotomy. This bilateral group was mobilised fully weight-bearing with crutches. During the same period 139 Ganz trochanteric osteoto-mies were performed for unilateral hip resurfacing. These patients were mobilised with crutches, weight-bearing up to 10 kg on the operated leg. Nine osteotomies (32%) in the bilateral group subsequently developed a symptomatic non-union requiring revision of fixation. This compares with 10 patients (7%) in the unilateral group. Applying the Fisher’s exact test, the difference reached significance (P=0.0004). In two patients a second revision was required to achieve union. In one patient, revision of trochanteric fixation precipitated a deep infection. Protected weight-bearing following a Ganz trochanteric osteotomy is important to the success of the procedure. Simultaneous bilateral hip arthroplasty through a Ganz approach should be avoided. If it is undertaken, we recommend that patients should be non weight-bearing for 6 weeks following surgery. Non-union following a Ganz trochanteric osteotomy for arthroplasty carries a significant morbidity.

Abstract (sommario):

Background: In order to overcome the geometrical and physical limitations of conventional rotating and piezosurgery instruments used to perform bone osteotomies, as well as the difficulties in translating digital planning to the operating room, a stand-alone robot-guided laser system has been developed by Advanced Osteotomy Tools, a Swiss start-up company. We present our experiences of the first-in-man use of the Cold Ablation Robot-guided Laser Osteotome (CARLO®). Methods: The CARLO® device employs a stand-alone 2.94-µm erbium-doped yttrium aluminum garnet (Er:YAG) laser mounted on a robotic arm. A 19-year-old patient provided informed consent to undergo bimaxillary orthognathic surgery. A linear Le Fort I midface osteotomy was digitally planned and transferred to the CARLO® device. The linear part of the Le Fort I osteotomy was performed autonomously by the CARLO® device under direct visual control. All pre-, intra-, and postoperative technical difficulties and safety issues were documented. Accuracy was analyzed by superimposing pre- and postoperative computed tomography images. Results: The CARLO® device performed the linear osteotomy without any technical or safety issues. There was a maximum difference of 0.8 mm between the planned and performed osteotomies, with a root-mean-square error of 1.0 mm. The patient showed normal postoperative healing with no complications. Conclusion: The newly developed stand-alone CARLO® device could be a useful alternative to conventional burs, drills, and piezosurgery instruments for performing osteotomies. However, the technical workflow concerning the positioning and fixation of the target marker and the implementation of active depth control still need to be improved. Further research to assess safety and accuracy is also necessary, especially at osteotomy sites where direct visual control is not possible. Finally, cost-effectiveness analysis comparing the use of the CARLO® device with gold-standard surgery protocols will help to define the role of the CARLO® device in the surgical landscape.

Abstract (sommario):

Background To evaluate the safety and effectiveness of posterior closed-open wedge osteotomy for treatment of congenital kyphosis in children. Methods Imaging and clinical data from January 2010 to December 2019 of posterior closed-open wedge osteotomy of congenital kyphosis with at least 2-year follow up was analyzed retrospectively. Perioperative indicators such as operation time, osteotomy site, osteotomy method and occurrence of complications, and imaging indicators were observed. The 3D printed models were used to measure the expanded distance of anterior edge vertebra and closed length of spinal canal line. The clinical effect was evaluated through SRS-22 questionnaires. Results There were 15 CK patients in this study. The osteotomy segments and details are as follows: 1 case each for T6-9 and L2, 2 cases at T11, 3 cases at T12, and 6 cases at L1. The average operation time was 314 min, the average blood loss was 970 mL, the average fusion range was 6.3 segments, and the average time of follow up was 70.5 months. The Cobb angle of local kyphosis was corrected from 65.6 ± 18.8° to 11.3 ± 7.1°( p < .001). The range of kyphosis correction was 40–90°, and average correction rate was 83.2% (67.7–95.7%). The correction was stable in follow-up, and the kyphotic angle was 11.0 ± 7.6 ( p = .68). The preoperative SVA was 31.5 ± 21.8 mm, and the postoperative recovery was 18.0 ± 15.5, while the last follow-up was 9.1 ± 7.9. The p values were 0.02 and 0.07 respectively. By using 3D printed models, the expanded distance of anterior edge vertebra and closed length of spinal canal line were 14.5 ± 7.5 mm and 24.5 ± 8.0 mm respectively. Self-image and satisfaction in SRS-22 improved significantly. There was no recurrence of deformity and junctional kyphosis. Conclusions The posterior closing-opening wedge osteotom for treatment of congenital kyphosis in children is satisfactory, if selected appropriately. During the longitudinal follow-up, the patients could achieve solid fusion and the correction could be well maintained. Evidence of Confidence: IVa
