Актуальность. Изучение особенностей гемодинамики в зоне пораженного артрозом коленного или тазобедренного сустава при трансплантации является актуальной задачей, так как позволяет уже на ранних стадиях послеоперационного периода корригировать терапевтические вмешательства направленные на улучшение кровоснабжения и предупреждение развития тромбоэмболических осложнений. Цель исследования - изучение микроциркуляторных гемодинамических нарушений в зоне пораженных артрозом суставов в до и послеоперационном периоде. Методика. Исследования проведены на 136 пациентах, разделенных на 2 группы: в 1-ю группу вошли 46 больных с артрозами тазобедренного или коленного суставов I-II стадии, 2-ю группу составили 90 больных с аналогичными артрозами III-IV степени. Исследования проводились в предоперационном периоде и на 6-е сут после эндопротезирования. Состояние кровотока изучали с помощью датчика mDLS. Использовали авторскую методику спектрального разложения сигнала на частотные компоненты, связанные с гемодинамическими источниками различной скорости сдвига слоев крови. Для интерпретации результатов многочастотного анализа использовали гемодинамический индекс (Hemodynamic Index, HI): низкочастотный (HI1), определяемый медленным межслоевым взаимодействием, высокочастотный (HI3), характеризующий быстрые процессы сдвига слоев и HI2 занимающий промежуточное положение (прекапиллярный и капиллярный кровоток). Рассчитывали относительные индексы RHI1, RHI2 и RHI3 обозначающие нормированный (относительный) вклад каждой компоненты индекса в общие динамические процессы. Для каждого компонента HI (HI1, HI2, HI3) использовали дополнительную меру медленных колебаний кровотока - осцилляторный гемодинамический индекс (OHI). Определяли следующие OHI, храктеризующие движение крови: ассоциированное с эндотелием (NEUR), вызываемое мышечным слоем сосудов (MAYER), задаваемое дыхательным циклом (RESP) и пульсовыми толчками (PULSE). Результаты. B зоне проекции больного сустава по сравнению со здоровым резко снижены гемодинамические индексы HI1 и НI2, а также RHI1 и RHI2. Одновременно в зоне пораженного сустава резко возрастает величина гемодинамических индексов HI3 и RHI3, что свидетельствует об усилении сдвига в осевом потоке, а также значительно увеличивается осцилляторный индекс MAYER1. После трансплантации сустава в зонах проекции здорового и пересаженного сустава практически сохраняются те же различия, что и в дооперационном периоде. Одновременно в послеоперационном периоде уменьшаются индексы PULSE1 и PULSE3. В зоне проекции здорового сустава после операции отмечается увеличение осцилляторных индексов MAYER1 и MAYER2 и снижение индекса PULSE1. В зоне пораженного сустава в послеоперационном периоде увеличивается соотношение HI1/HI3, что может быть связано с усилением эндотелиальной дисфункции. Заключение. Представленные данные свидетельствуют о том, что в зоне пораженного сустава развиваются значительные нарушения микрогемодинамики, что не может не сказаться на течении патологического процесса. Studying hemodynamics in the area of the knee or hip joint affected by arthrosis during transplantation is a significant task. Such studies would allow adjustment of the treatments aimed at improving the blood supply and preventing thromboembolic complications already in early postoperative period. Aim. To study microcirculatory hemodynamic disorders in the area of joints affected by arthrosis in the pre- and postoperative periods. Methods. The study included 136 patients divided into 2 groups: the first group consisting of 46 patients with stage 1-2 arthrosis of the hip or knee joint and the second group consisting of 90 patients with stage 3-4 arthrosis of the same kind. The study was performed in the preoperative period and on Day 6 after joint arthroplasty. The state of blood flow was evaluated with a mDLS transducer using the authors’ method of spectral signal decomposition into the frequency components related with hemodynamic sources of different shear rates of blood layers. For interpretation of results of the multifrequency analysis, the hemodynamic index (HI) was used: low-frequency HI (HI1) determined by the slow interlayer interaction, high-frequency HI (HI3) that characterizes fast processes of the shear of layers, and HI2 that is intermediate (precapillary and capillary blood flow). Relative indexes, RH1, RH2, and RH3, were calculated, which designate a normalized (relative) contribution of each component of the index to overall hemodynamic processes. For each HI component (HI1, HI2, HI3), an additional measure of slow circulatory fluctuations was used, the oscillatory hemodynamic index (OHI). The following OHIs, that characterize the blood flow, were determined: endothelium-associated (NEUR), determined by the vascular muscular layer (MAYER), respiratory cycle-driven (RESP), and pulse impulses (PULSE). Results. In the projection zone of the affected joint as compared with the healthy one, the hemodynamic indices HI1 and HI2, as well as RHI1 and RHI2, were sharply reduced. At the same time, the hemodynamic indices HI3 and RHI3 were sharply increased in the area of the affected joint, which indicated an increase in the axial flow shear; the oscillatory index MAYER1 was also significantly increased. After joint transplantation, practically the same differences as in the preoperative period were maintained in the projection zones of the healthy and the transplanted joints. At the same time, the PULSE1 and PULSE3 indices decreased in the postoperative period. In the projection area of the healthy joint after surgery, the oscillatory indices MAYER1 and MAYER2 were increased whereas the PULSE1 index was decreased. In the area of the affected joint in the postoperative period, the HI1/HI3 ratio was increased, which could have been due to aggravated endothelial dysfunction. Conclusion. Significant microhemodynamic disorders develop in the area of the affected joint, which must affect the course of the pathological process.

Incorrectly developed acetabulum and subluxated hip joint may cause many problems for proper implantation of endoprosthesis. The aim of this work is to assess the radiological results of offset restoration and selection of endoprosthesis implant in a dysplastic hip joint. The study group consisted of patients who had a surgery in the period between 2016 and 2018. All of them had a cementless total hip endoprosthesis. The group consisted of 91 patients (96 hip joints), with an average age of 42 years (31-47 years). 55 left and 41 right hip joints. 70 females and 21 males. The control group consisted of patients who were not diagnosed with hip joint dysplasia. The control group consisted of 70 patients (70 hip joints), with an average age of 35 years (19-55 years). 53 females and 17 males. The radiographic assessment included the measuring of medialization and distalization which describe the offset of hip joint. The joint decentration was classified according to Crowe. Based on radiographic measurements we have achieved statistically significant (p<0.05) changes in medialization and distaliza- tion parameters. We have not noticed a statistically significant difference for medialization parameter (p=0.8259) after a surgery when compared to the control group. For all patients we have achieved a restoration of correct offset in the horizontal plane. The main idea behind endoprosthesis in a dysplastic coxarthosis is the implantation of endoprosthesis cup in an anatomically correct location. Small screw- in cup and conical stem offer great possibility of restoring correct offset of a dysplastic hip joint.

Testo completoAbstract (sommario):
The hip joint is a ball and socket joint that supports body weight and is responsible for locomotion. Hip replacement surgery is mostly performed when hip pain significantly impedes daily life activities and when non-surgical treatments are ineffective in certain cases. The most common cause of hip replacement is damaged hip joint, which can cause arthritis. Therefore, physical therapy after the replacement surgery of major joints is generally considered helpful for a good prognosis. However, if the patients are given the usual care recommended by the surgeons, the patients recover in the same manner as they do with the physical therapy sessions or the physical therapy usually accelerates the recovery process and prevents future complications. Thus, the current study provides a comprehensive of the recovery of patients who have undergone hip arthroplasty, with or without physical therapy training programs.

Testo completoAbstract (sommario):
Background: Gunshot injury of the hip joint was reported to constitute 2–17% of all extremity firearm injuries. However, there are few studies in the literature related to gunshot injuries of the hip joint. The aim of the current study was to present the results of 10 cases treated with arthroplasty following a gunshot injury to the hip joint together with the recommended treatment algorithm. Methods: Patients with a previous medical history of hip joint region gunshot injury who underwent total hip arthroplasty were retrospectively evaluated. Those with incomplete medical records or who were lost to follow-up were excluded. Patients were classified according to the severity of the previous gunshot injury to the hip joint region. Harris hip score (HHS) and Short Form-12 quality of life score were the main outcome measurements. Postoperative complications encountered during follow-up were recorded. Results: The mean age of the patients at the time of surgery was 29.9 years. The mean preoperative HHS was 25.2 points and it was 65.8 at the final follow-up. Patients with bullet fragments in the hip joint, classified as group 1, had better HHS, whereas those with contaminated hip joint with intestinal flora, classified as group 3, had worst HHS. Conclusion: Hip arthroplasty after hip joint gunshot injury is a good treatment choice in young patients to reduce pain and regain functions. However, very high infection rates can be seen in patients with accompanying intestinal injury.

Abstract Objective To determine whether dorsolateral subluxation (DLS) of the femoral head reflects osseous conformation of the coxofemoral (hip) joint and represents a property distinct from maximum passive laxity of the hip joint in dogs. Animals 14 Labrador Retrievers, 16 Greyhounds, 58 Greyhound-Labrador Retriever mixed-breed dogs, and 1 Rottweiler. Procedures DLS of the femoral head (DLS score) and passive laxity of the hip joint (distraction index) were determined radiographically in 3 groups of dogs: not treated (167 joints of 84 dogs); before and after injecting 2 ml of hyaluronan into 25 hip joints of 13 dogs; and before and after unilateral triple pelvic osteotomy in 5 dogs. Results of the 2 methods were compared for each group. Results In untreated dogs, the correlation coefficient (r) of DLS score versus distraction index was −0.73 and −0.69 for 84 left and 83 right hip joints, respectively. Mean coefficient of determination (r2) for both hips was 0.5. Mean DLS score did not differ before and after intra-articular injection of hyaluronan into either hip joint, whereas mean distraction index increased significantly after intra-articular injection. Unilateral triple pelvic osteotomy resulted in a significant increase in DLS score, compared with values obtained before surgery. However, distraction index before and after surgery did not differ significantly. Conclusions and Clinical Relevance The DLS test assesses the congruity of the acetabulum and the femoral head in a canine hip joint and thus represents a characteristic distinct from maximum passive laxity. The DLS score and the distraction index evaluate different components of hip joint stability. (Am J Vet Res 1999;60:1571–1576)

Aim. To analyze the long-term results of treatment of patients with arthrosis and hip dysplasia treated by Ganz osteotomy.
Methods. 71 patients operated by Ganz osteotomy in 1995-2010 were examined. A total of 83 joints were operated. Tonnis, Wiberg, Leguesne angles, joint medialization, head coating index were measured. The arthrosis degree was determined radiologically according to Tonnis classification. Patients included 58 women and 13 men. Hip joint status was evaluated using the Harris Hip Score (HHS) system.
Results. Ganz osteotomy resulted in radiological parameters improvement: Tonnis angles improved by 65.6%, Wiberg - by 5 times, Lequesne - by 6.7 times. Medialization improved by 18.2%, the coating index - by 40.3%. Radiological arthrosis degree according to Tonnis classification was 0 in 43 joints, 1 - in 4 joints before surgery. After surgery, during examination arthrosis degree was 0 - in 18 joints, 1 - in 38,2 - in 20,3 - in 7 cases. In 21 joints the transition from the 0 to the 1st arthrosis degree, in 4 joints - from 0 to the 2nd degree was registered. In 16 joints transition from the 1st to the 2nd arthrosis degree was registered, in 7 joints - from the 1st to the 3rd degree. As a result of the treatment hip joint functional parameters improvement was found, the HHS rate before the surgery was 62.6 points, after the surgery - 82.8 points. The minor and major complications rate measured up to 23 and 15% respectively.
Conclusion. Patients were examined 7.5 years after the surgery in average; in our series, total prostheses after osteotomy was performed in 3 patients (4 joints), in one case, due to postoperative subluxation Schanz osteotomy was performed; it was managed to preserve biological joint in 95.18% of cases.

Background Older adults with hip joint osteoarthritis, a major cause of chronic progressively disabling highly painful functional experiences, may require a surgical joint replacement procedure known as total joint arthroplasty surgery. Objective This review aimed to address the question of whether there an association between hip joint arthroplasty infection rates and prevailing pre or preoperative vitamin D levels that warrants consideration in efforts to prevent or minimize infection related hip arthroplasty complications among older adults particularly during the current ongoing COVID-19 pandemic. Methods PUBMED, SCOPUS, and WEB OF SCIENCE articles related to the topic and published between January 2016-2021 were searched, examined, and summarized. Results Older adults with hip joint osteoarthritis and low vitamin D serum levels who undergo total hip joint arthroplasty surgery may be at higher risk for post-operative infections than those with adequate vitamin D serum levels. Conclusion More research to verify whether efforts to screen for, and maximize vitamin D levels, before and after surgery, as indicated, may be helpful in the context of minimizing total hip joint arthroplasty surgery infection susceptibility and severity among older vitamin D deficient severely disabled hip osteoarthritis cases.

Testo completoAbstract (sommario):
BACKGROUND: Knee and hip joints endoprosthetics are the main surgical method of arthrosis treatment. The epidemiological incidence rate of the disease is growing steadily every year, affecting younger and younger people. Despite the proven tactics of joint endoprosthetics, an important issue is quality planning of surgery.
AIM: The aim of this research is to develop a device and a method that would contribute to solving the existing challenges of pre-surgery planning of hip endoprosthetics in patients with related pathologies, which have caused compensatory deformation, and making long vertebrarium-pelvis-lower limbs scout images with the patient lying on his back with an axial load in a computer tomography.
METHODS: Analog X-ray photographs of the pelvis made on film, digital DICOM images, and special planning programs are used for planning. However, according to numerous studies, the disease of the hip joint is not an independently isolated pathology. In most cases, this pathology is accompanied by changes in the lumbar spine. Often, patients prepared for endoprosthetics have a congenital deformity of tarsus or hip segment, which, during the knee, joint endoprosthetics surgery causes difficulties with the installation of an intramedullary guide.
RESULTS: The results after total knee arthroplasty according to the method modified at the Department showed a reduction of the WOMAC index slightly more than twice down to 37.26 ± 7.92. The number of revision surgeries after endoprosthetics decreased from 5 (5.7%) to 1 (1.1%) for the hip joint, and from 7 (4.3%) to 2 (1.3%) for the knee joint, respectively.
CONCLUSION: To form a proper guide entry point, it is necessary to assess the segment at the stage of surgery planning and examination of patients, which can be done using the proposed method. To remove the complications during the pre-surgery planning of hip joint endoprosthetics in patients with related pathologies, a device and methods have been developed for obtaining long topograms of the vertebrarium-pelvis-lower limbs complex with the patient lying on his back with the axial load in computer tomography.

Testo completoAbstract (sommario):
The aim of the study is to demonstrate, using a clinical example, the possibility of treating a patient with a severe acetabular defect by performing a one-stage revision arthroplasty using an individual design.
Materials and methods. A 45-year-old female patient was admitted with complaints of pain, limitation of movement in the right hip joint, and gait disturbance. From anamnesis at the age of 5 years, reconstructive operations of the hip joints were performed. In 1991, CITO performed primary total arthroplasty of the right hip joint with an endoprosthesis from ESKA Implants. In 1998, due to the instability of the acetabular component of the total endoprosthesis of the right hip joint, revision arthroplasty was performed, and the cup was placed with a cement fixation. In 2001, for left-sided dysplastic coxarthrosis, primary total arthroplasty of the left hip joint was performed. In 2012, due to the instability of the total endoprosthesis of the left hip joint, revision arthroplasty was performed using an ESI anti-protrusion ring (ENDOSERVICE) with a cement cup and a Zweimller-type femoral component; the femur defect was repaired using a fresh frozen cortical graft. In October 2019, instability of the total endoprosthesis of the right hip joint was revealed, for which revision endoprosthetics was performed using an individual acetabular component.
Results. The HHS index before revision arthroplasty was 21 points, after 1 month after surgery 44 points, after 3 months after surgery 65, after 6 months 82. Quality of life was assessed according to the WOMAC scale: before surgery 73 points, after 1 month after surgery 54 points, after 3 months 31, after 6 months 15 points. At the time of the last consultation, the patient moves with a cane, lameness persists, associated with scar reconstruction and atrophy of the gluteal muscles.
Conclusion. The use of individual structures allows to restore the support ability of the lower limb and the function of the hip joint in the case of an extensive defect of the pelvic bones of the pelvic discontinuity type.

Testo completoAbstract (sommario):
Abstract Hip arthroscopic surgery for femoroacetabular impingement and periacetabular osteotomy (PAO) for dysplasia is the most commonly used contemporary treatment for these conditions and has been shown to provide pain relief and restore function. What is less understood and perhaps of more interest to health economists, is the role of these procedures in preserving the hip joint and avoiding hip arthroplasty. The aim of this systematic review was to determine whether hip joint preservation surgery, indeed, preserves the hip joint by looking at conversion rates to total hip arthroplasty (THA). Two separate searches were undertaken, using PRISMA guidelines and utilizing PubMed and Open Athens search engines, identifying manuscripts that looked at conversion to THA following either hip arthroscopy (HA) or PAO. When considering HA, we found 64 eligible papers. Out of these studies, there were 59 430 hips with 5627 undergoing conversion to THA (9.47% [95% CI 9.23–9.71%]) with a mean conversion time of 24.42 months. Regarding PAO, there were 46 eligible papers including 4862 patients who underwent PAO with subsequent conversion to THA in 404 patients (8.31% [95% CI 7.54–9.12%]). with a mean conversion time of 70.11 months. Certain features were associated with increased conversion rates, including increasing age, worsening arthritis and joint space <2 mm. This study demonstrates that the mean conversion rates to be <10% for HA and PAO, during the mean follow-up periods of included manuscripts. Joint preserving surgery appears to defer or at least delay the need for THA.

Testo completoAbstract (sommario):
The success of hip implants with elderly recipients has encouraged surgeons to increasingly perform hip replacement surgery on younger, more active patients as well. The condition that causes hip prostheses to loosen is known as osteolysis. While the problem affects only a relatively small set of recipients now, it may well grow as hip replacement surgery encompasses a wider range of eligible patients. A research group at the University of Leeds in the United Kingdom says it has patented a ceramic-on-metal hip prosthesis that produces one-tenth the wear particles of currently available hip replacement joints. The prosthesis has been licensed to a prosthetic manufacturer and is about to enter clinical trials in Europe. Some companies produce highly cross-linked polyethylene, either by thermal treatment or by radiation. Stryker Orthopaedics has Crossfire hip implants using highly cross-linked polyethylene cups against a metal ball. The company developed a ceramic-on-ceramic joint replacement, which it commercialized in 2003. The new Trident joint uses bearing surfaces of alumina ceramic. The company claims it has scratch resistance, low wear rates, good wettability for lubrication, and no ion release.

For the period 2013-2015, 36 patients underwent revision surgery because of secondary developed complications after primary hip joint replacement surgery. 14 of them were male and 23 – female, with average age 73 years.
We examined 4 groups of patients depends on the complications type:
- Aseptic loosening in 23 patients, appeared 10 years’ average following primary hip prosthesis surgery.
- Septic loosening in 2 patients revealed on second to the tenth month post operatively. In two other patients we observed infected hematoma.
- Hip joint prosthesis (luxation) because of trauma or extremely wrong motion we notice in 5 patients. In one of them we revealed acetabular cup malposition.
- Periprosthetic fractures with aseptic loosening in 3 patients.
All 36 patients had primary cemented hip joint prosthesis.
In the first group depends on which prosthesis parts were loosened we did acetabular cup and femoral stem replacement in 15 patients, only acetabular cup replacement in 4 patients and in 3 patients only femoral stem replacement.
In 2 patients from second group we replaced the primary prosthesis by total spacer for 8 months followed by revision prosthesis surgery. In 2 haematoma patients we performed debridement, lavage-drainage and long term antibiotic treatment.
In 2 patients of third group we replaced the primary head with a longer one and in 3 other patients we replaced the primary acetabular cup by shoulder collar cemented cup.
In 2 patients of fourth group we replaced the primary acetabular cup and femoral stem by shoulder collar cemented cup and by revisionary stem delivered by Implant and Zimmer (Revitan). In the third patient we implanted revisionary femoral stem (Implant).
3 years after revisionary hip joint prosthesis surgery we monitor good prosthesis stability and good functional scores

Cervical cancer patients may experience hip problems related to the cancer itself or therapeutic management for the cancer. Septic arthritis should be one of the possibilities but there have been no reports on this. Here we present three patients who developed hip problems more than two years after radiotherapy with or without a radical operation. One patient was managed as septic arthritis because of significant inflammatory signs around the affected hip joint even though the causative organism was not confirmed. Succeeding total hip arthroplasty functioned well and had no recurrence of infection. The hip problems of the other two patients were diagnosed as radiation osteonecrosis of the femoral head initially. However, Bacteroides fragilis infection was found several months after total hip arthroplasties. Radiotherapy to the pelvis may damage the hip joint and compromise host-defense mechanisms of the pelvic region. Both factors may increase the possibility of infection of hip joints. Further clinical evidence is needed to understand whether subacute or chronic anaerobic infection could also be one of the causes leading to progressive destruction of the femoral head.

Background: Total hip arthroplasty (THA) for poliomyelitis is a problematic procedure due to difficulty in positioning the cup of the prosthesis in the true acetabulum and the risk of dislocation after THA due to the low muscle tone. Methods: We herein present a case of bilateral hip pain with a history of poliomyelitis. Radiograph showed bilateral hip osteoarthritis caused by hip dysplasia due to residual poliomyelitis in right hip joint or developing dysplasia of the hip joint in left hip joint. THA was performed to bilateral hip joints. Results: Six years after bilateral THA, bilateral hip pain significantly improved. Additionally, the muscle strength on the paralyzed right side partially improved. However, the muscle strength on the non-paralyzed left side did not significantly improve. No complications related to the surgery were observed. Conclusion: Promising early results were obtained for THA in our patient with residual poliomyelitis. However, surgeons should pay attention to the potential development of complications concerning THA that may arise due to the residual poliomyelitis.

Testo completoAbstract (sommario):
Introduction. Pathological dislocation of the hip is one of the most severe complications of acute hematogenous osteomyelitis. The program of treatment for children with pathological hip dislocation is complex, but it has been sufficiently developed and implemented very successfully. At the same time, the available literature provides no cases of treating children with bilateral pathological hip dislocations after hematogenous osteomyelitis. There is no information on the incidence of such cases or in regards to remote functional results.
Materials and methods. The results of the treatment of 18 children with bilateral pathological dislocation of the hip after hematogenous osteomyelitis are presented, which constituted 23.1% of the total number of patients (78) who underwent surgery in 2000–2016 for the diagnosis of pathological hip dislocation. Both hip joints were surgically operated on in 12 patients, while one hip joint was operated on in 6 patients. To assess the anatomical and functional state of hip joints, the clinical and roentgenological diagnostic techniques were used.
Results and discussion. To stabilize and restore the function of the hip joints, 18 children underwent 30 surgical interventions: simple open hip reduction (19) and open hip reduction with hip arthroplasty with one (6) or two (5) demineralized osteochondral allogeneic grafts. The decision regarding the possibility of performing surgical intervention on the second hip joint was made only after a child's check-up examination was complete and after positive information about the anatomical and functional state of the operated hip joint was obtained. According to these criteria, 14 (77.8%) children underwent surgical treatment of the second hip joint 1–1.5 years after the course of conservative measures to restore the range of motion in the previously operated hip joint.
Over a period of 1–12 years, 17 patients were examined, 10 of which underwent an operation on both sides (27 joints). The preservation of up to 80º or more of motion amplitude was noted in 17 (62.9%) of 27 operated hip joints. When assisting patients with pathological hip dislocation, it is necessary to understand that it is practically impossible to restore the affected joint to the anatomical state of the opposite unaffected joint. As for the bilateral lesion, this is most certainly impossible, and the development of arthrosis is inevitable. Therefore, the most important factor reflecting the degree of well-being and stability of the affected joint is the amplitude of active movements. Preserving this amplitude in the affected joints with a careful and attentive attitude is a fundamental and feasible task.

Testo completoAbstract (sommario):
The hip implant is a very successful treatment for serious osteoarthritis, especially in older patients, but less desirbale for earlier interventions. There is a growing consensus that most hip arthritis is due to shape abnormalities that cause impingement at the ball and socket, collectively called femoroacetabular impingement (FAI). The ball does not fit accurately into the socket, leading to premature wear, and then destructive arthritis. It is not then necessary to replace the whole hip joint; newly developed surgical techniques that accurately reshape the bones to relieve impingement and reduce wear have been shown to be effective. This surgery can be performed with a conventional open approach, or be arthroscopic (keyhole) surgery. It would be better to reshape bones to suit each individual patient. Finite element methods (FEM) have been widely used for biomechanical studies of hip implants and periacetabular osteotomy, but hardly at all in hip reshaping. Non-linear FEM is employed in the current study to perform biomechanical evaluations of differences in contact pressure between normal and arthritic hip joints to help basic understanding and lead to more accurate surgery. The hip joint bone structure is obtained through a medical CT scan and then the CT images have been converted into a format readable by FEM solvers. A sophisticated non-linear contact model of the hip joint bringing together the interactions of true geometry, natural movement and contact forces has been established using this advanced FEM.

Aims Pelvic tilt is believed to affect the symptomology of osteoarthritis (OA) of the hip by alterations in joint movement, dysplasia of the hip by modification of acetabular cover, and femoroacetabular impingement by influencing the impingement-free range of motion. While the apparent role of pelvic tilt in hip pathology has been reported, the exact effects of many forms of treatment on pelvic tilt are unknown. The primary aim of this study was to investigate the effects of surgery on pelvic tilt in these three groups of patients. Methods The demographic, radiological, and outcome data for all patients operated on by the senior author between October 2016 and January 2020 were identified from a prospective registry, and all those who underwent surgery with a primary diagnosis of OA, dysplasia, or femoroacetabular impingement were considered for inclusion. Pelvic tilt was assessed on anteroposterior (AP) standing radiographs using the pre- and postoperative pubic symphysis to sacroiliac joint (PS-SI) distance, and the outcomes were assessed with the Hip Outcome Score (HOS), International Hip Outcome Tool (iHOT-12), and Harris Hip Score (HHS). Results The linear regression model revealed a significant negative predictive association between the standing pre- and postoperative PS-SI distances for all three groups of patients (all p < 0.001). There was a significant improvement in all three outcome measures between the pre- and postoperative values (p < 0.05). Conclusion There is a statistically significant decrease in pelvic tilt after surgery in patients with OA of the hip, dysplasia, and femoroacetabular impingement. These results confirm that surgery significantly alters the pelvic orientation. Pelvic tilt significantly decreased after total hip arthroplasty, periacetabular osteotomy, and arthroscopy/surgical hip dislocation. The impact of surgery on pelvic tilt should be considered within the therapeutic plan in order to optimize pelvic orientation in these patients.

Aims The preventive effects of bisphosphonates on articular cartilage in non-arthritic joints are unclear. This study aimed to investigate the effects of oral bisphosphonates on the rate of joint space narrowing in the non-arthritic hip. Methods We retrospectively reviewed standing whole-leg radiographs from patients who underwent knee arthroplasties from 2012 to 2020 at our institute. Patients with previous hip surgery, Kellgren–Lawrence grade ≥ II hip osteoarthritis, hip dysplasia, or rheumatoid arthritis were excluded. The rate of hip joint space narrowing was measured in 398 patients (796 hips), and the effects of the use of bisphosphonates were examined using the multivariate regression model and the propensity score matching (1:2) model. Results A total of 45 of 398 (11.3%) eligible patients were taking an oral bisphosphonate at the time of knee surgery, with a mean age of 75.8 years (SD 6.2) in bisphosphonate users and 75.7 years (SD 6.8) in non-users. The mean joint space narrowing rate was 0.04 mm/year (SD 0.11) in bisphosphonate users and 0.12 mm/year (SD 0.25) in non-users (p < 0.001). In the multivariate model, age (standardized coefficient = 0.0867, p = 0.016) and the use of a bisphosphonate (standardized coefficient = −0.182, p < 0.001) were associated with the joint space narrowing rate. After successfully matching 43 bisphosphonate users and 86 non-users, the joint narrowing rate was smaller in bisphosphonate users (p < 0.001). Conclusion The use of bisphosphonates is associated with decreased joint degeneration in non-arthritic hips after knee arthroplasty. Bisphosphonates slow joint degeneration, thus maintaining the thickness of joint cartilage in the normal joint or during the early phase of osteoarthritis.

Testo completoAbstract (sommario):
Introduction: A degenerative disease of a hip joint (osteoarthritis) is a chronic affliction which causes progressive degeneration of a hip joint and tissue located around it. It inflicts limitation of locomotor skills, deteriorates life quality to a significant extent, and prevents a patient from normal activities in daily life. In Poland, more than 3 million people suffer from osteoarthritis. The disease symptoms are pain, limitation of mobility scope in a joint, postural and gait disorders, and positioning of a lower limb in non-functional position. The aim of the study was to analyze the gait pattern and to assess the static and dynamic balance of people qualified for hip joint arthroplasty, as well as possibility of falling.Material and methods: The Tinetti Test has been used for the research in question. This test has been completed in patients awaiting for hip joint arthroplasty, and once more on a third day upon completion of arthroplasty, in the Department and Clinic of Orthopaedics, Traumatology and Oncology of Locomotor System of the Pomeranian Medical University in Szczecin. This test has included a group of 31 – 11 women and 20 men.Results: The mean age of the research group was 65.1 years. The intensity of pain in the hip joint, based on the VAS scale before and after the procedure, was 6.53 and 5.22 points, respectively. The average number of points obtained by the patient in the Tinetti Test before the surgery was 22.71 points. On the third day of hip surgery, the mean number of points decreased to 18.81 points.Conclusions: Patients treated with alloplastic surgery of a hip joint show lower static and dynamic balance. Upon completion of the surgery, the patients are more prone to fall. The patients with completed hip joint arthroplasty show symptoms of locomotor system disorders.

Objectives: Traction force widens the joint space during hip arthroscopy. It is unclear how much the traction force varies and if it is related to the joint space widening. Main goal of our study was to measure the amount of force needed to widen the hip joint. Second goal was to study the relation between this force and the amount of joint space widening. Methods: Traction force was measured in 27 patients (of whom 24 female, mean age 41) during arthroscopy. Measurements were performed before the procedure, after vacuum seal release and after capsulotomy. Joint space widening was measured with fluoroscopy and was calibrated. Friedman and Wilcoxon tests were used to measure differences in traction. The Spearman’s rho correlation coefficient was used to identify a correlation in traction force and joint space widening. Regression analyses were used to identify relations between age, body mass index (BMI), hip degeneration and traction force. Results: The median traction force before arthroscopy was 714 N, lowered to 520 N after vacuum seal release and to 473 N after capsulotomy ( p < 0.001). Median joint space widening was 8.8 mm. Spearmans’ rho correlation between traction force and joint space widening was ‒0.13. Discussion: Median traction force of 714 N resulted in 8.8 mm of joint space widening. This traction force was significantly lowered by 200 N after release of the vacuum seal of the hip and 250 N after additional capsulotomy without loss of joint space narrowing. No significant relation was identified for age, BMI or progression of the Kellgren-Lawrence classification for hip degeneration and traction force. Netherlands Trial Registry number 8610

The lesion of the hip joint with ankylosing spondylitis (AS) is an unfavorable prognostic sign and can lead to the endoprosthetics (EP) of the joint. Objective. to evaluate the results of the EP of the hip joints in patients with AS with joint dynamic observation by a rheumatologist and orthopedist during the first year after surgery. Materials and methods. The results of the EP of the hip joint of 120 patients in three groups of one central study were analyzed. The 1st and 2nd groups consisted of patients with ankylosing spondylarthrosis after endoprosthetics of the hip joint, but with various options for maintenance in terms of basic therapy, and the 3rd group with coxsartrosis after planned replacement of the joint. Dynamic observation by the rheumatologist and orthopedist was carried out before the operation, after the operation, after 6 and 12 months. Results. The effectiveness of arthroplasty of large joints with a reliable (p <0.05) decrease in pain (VAS) in the first month after EP, improving functional capacity (BASFI) and a decrease in ASDAS (ASDAS) after 6 and 12 months after EP. There were no complications after the operation. A clinical example of a patient with a severe course of ankylosing spondylitis and the effectiveness of arthroplasty is presented. Conclusion. EP of the hip joints in patients with spondiloarthritis is effective not only in terms of improving the functional ability and removing pain, but also to reduce the activity of the disease as a whole

Removal of bullets retained within joints is indicated to prevent mechanical blockade, 3rd body wear and resultant arthritis, plus lead arthropathy and systemic lead poisoning. The literature is sparse on this subject, with mostly sporadic case reports utilizing hip arthroscopy. We report on the largest series of removal of bullets from the hip joints using open surgical.We reviewed prospectively collected data of patients who presented to a single institution with civilian gunshot injuries that breached the hip joint between 01 January 2009 and 31 December 2022.We included all cases where the bullet was retained within the hip joint area. Exclusion criteria: cases where the hip joint was not breached, bullets were not retained around the hip area or cases with isolated acetabulum involvement.One hundred and eighteen (118) patients were identified. One patient was excluded as the bullet embedded in the femur neck was sustained 10 years earlier. Of the remaining 117 patients, 70 had retained bullets around the hip joint. In 44 patients we undertook bullet removal using the followingsurgical hip dislocation (n = 18), hip arthrotomy (n = 18), removal at site of fracture fixation/replacement (n = 2), posterior wall osteotomy (n = 1), direct removal without capsulotomy (tractotomy) (n = 5).In 26 patients we did not remove bullets for the following reasons: final location was extra-capsular embedded in the soft tissues (n=17), clinical decision to not remove (n=4), patients’ clinical condition did not allow for further surgery (n= 4) and patient refusal (n=1). No patients underwent hip arthroscopy.With adequate pre-operative imaging and surgical planning, safe surgical removal of retained bullets in the hip joint can be achieved without the use of hip arthroscopy; using the traditional open surgical approaches of arthrotomy, tractotomy and surgical hip dislocation.

Abstract The aim of this case study is to present arthroscopic treatment of recurrent hip instability after acute post-traumatic posterior hip dislocation with a fracture of the posterior acetabular wall. A male patient aged 35 suffered a dislocation of the right hip joint with a fracture of the posterior acetabular wall due to an accident. The fracture was stabilized during emergency surgery with a locking compression plate, and the patient was released home in a hip brace. Multiple dislocations of the hip joint followed with the implant being confirmed as stable. Decision was made to qualify the patient for a right hip arthroscopy. During the surgery, ligamentum teres was reconstructed using gracilis and semitendinous muscle grafts, followed by the labrum and joint capsule repair, where the surgery that stabilized the acetabular wall fracture had damaged them. There were no complications following the procedure. Short-term follow-up of 3 months demonstrates the patient has a stable hip, reduced pain and has returned to pre-injury activities.

In many Western countries, long waiting times for elective surgery are a concern. Major joint replacement is an example of a type of surgery with a high volume of demand and relatively long waiting periods for patients. As populations get older, the prevalence of slowly progressive diseases, such as osteoarthritis (OA) in hip and knee joints, is increasing. Over three-quarters of a million total hip and knee replacement surgeries are done in the United States annually (1). Furthermore, according to March et al. (1997), the costs of OA have been estimated to account for up to 1–2.5 percent of the Gross National Product (GNP) in several developed countries (2). In Finland, a total of 11,104 total joint replacements (TJRs) were performed in 2004 (hip 6,600 and knee 5,905), with the median waiting time of 181 days for the surgery (hip 153 and knee 209 days). Until 2007, the number of TJRs was 17,334 (hip 7,698 and knee 9,636), with a median waiting time of 120 and 142 days, respectively (3;4). The mean waiting time for elective surgical procedures is approximately 3 months in several countries and the maximum waiting times can stretch into years.

Introduction: Microsoft Kinect V2® (Kinect) is a peripheral device of Xbox® and acquires information such as depth, posture, and skeleton definition. In this study, we investigated whether Kinect can be used for human gait analysis. Methods: Ten healthy volunteers walked 20 trials, and each walk was recorded by a Kinect and infrared- and marker-based-motion capture system. Pearson’s correlation and overall agreement with a method of meta-analysis of Pearson’s correlation coefficient were used to assess the reliability of each parameter, including gait velocity, gait cycle time, step length, hip and knee joint angle, ground contact time of foot, and max ankle velocity. Hip and knee angles in one gait cycle were calculated in Kinect and motion capture groups. Results: The coefficients of correlation for gait velocity (r = 0.92), step length (r = 0.81) were regarded as strong reliability. Gait cycle time (r = 0.65), minimum flexion angle of hip joint (r = 0.68) were regarded as moderate reliability. The maximum flexion angle of the hip joint (r = 0.43) and maximum flexion angle of the knee joint (r = 0.54) were regarded as fair reliability. Minimum flexion angle of knee joint (r = 0.23), ground contact time of foot (r = 0.23), and maximum ankle velocity (r = 0.22) were regarded as poor reliability. The method of meta-analysis revealed that participants with small hip and knee flexion angles tended to have poor correlations in maximum flexion angle of hip and knee joints. Similar trajectories of hip and knee angles were observed in Kinect and motion capture groups. Conclusions: Our results strongly suggest that Kinect could be a reliable device for evaluating gait parameters, including gait velocity, gait cycle time, step length, minimum flexion angle of the hip joint, and maximum flexion angle of the knee joint.

Total Hip Joint Replacement Surgery is the procedure of surgical removal of cartilage in the hip joints damaged by disease osteoarthritis to replaced with artificial components. Total Hip Joint Replacement has been indicated to relieve pain in the pelvis due to degenerative joint disease. In Indonesia, this procedure has been practised, but due to the cost of expensive products resulting in limited only to upper classify patients. The high prices caused by importing prostheses products, the technological capabilities and the difficulty to meet the standards of medical devices. The regulation of the Minister of Health of the Republic of Indonesia Number 52, 2016 for standard rates in organising health services Health Assurance Program, explained that the action of these operations entered into the insurance claims BPJS program, but not for the prostheses. This paper discusses the introduction of the development of the hip joint prostheses made from a local material that’s SS 316L, PEEK and Ceramic Dental Stone. The result of this development is the product of the hip joint prostheses has a reasonable price with good quality so that it can become affordable for middle to lower patients.

Total hip arthoplasty (THA) in school children with secondary hip arthritis is the least studied treatment in orthopedic surgery. The need for THA arises much less often in children than in adults, but is a pressing problem. Indications for joint replacement at the age of 12–17 years include secondary hip arthritis of various etiologies such as dysplastic (congenital and paralytic), posttraumatic, infectious allergic (juvenile rheumatoid arthritis and Bechterew’s disease), postinfectious (osteomyelitis and tuberculosis of the joints hip joint) associated with severe pain, joint contractures, and decreases in motor activity. The aim of this study was to evaluate the effectiveness of THA in adolescents with stage 3 hip arthritis. A two-stage method of surgical treatment in cases of limb shortening of >4 cm is proposed. We present the results of the treatment in 45 patients. The proposed surgical technique achieved satisfactory results in 68% of the cases. The method allowed the restoration of hip joint function and limb length in all patients. Based on these results, we recommend the use of this method in the treatment of severe forms of secondary coxarthrosis as a result of dysplastic, paralytic, postinfection, systemic autoimmune, and posttraumatic processes.

Objectives: Hip instability secondary to capsular insufficiency is a cause of persistent pain and/or functional disability following primary hip arthroscopy in a poorly defined subset of patients. Further, an easily distractible hip exam under anesthesia is a finding that has been described in the diagnosis of hip instability; however, the exam has relied on subjective findings of a perceived looseness and has lacked objective criteria. The purpose of this study was to compare intraoperative hip joint distractibility between hips that previously underwent arthroscopic surgery and the contralateral hip with no history of surgical manipulation. Methods: Patients undergoing revision hip arthroscopy between April 2019 and December 2020, who previously underwent arthroscopic hip surgery for femoroacetabular impingement syndrome, were prospectively enrolled. Exclusion criteria was any contralateral hip surgery. Prior to instrumentation, fluoroscopic images of both hips were obtained at 25 lb traction intervals up to 100 lbs. Total joint space and distraction were measured at each traction interval. (Figure 1) Distraction was calculated as the difference between the baseline joint space and the total joint space at each subsequent traction interval. (Figure 2) Wilcoxon signed ranks tests and McNemar tests were used to compare distraction between revision and native contralateral hips. Results: Forty-seven patients were included. Mean distraction of operative hips was significantly greater than mean distraction of non-operative hips at traction intervals of 50 lbs (2.13 vs. 1.04 mm, p = 0.002), 75 lbs (6.39 vs. 3.70 mm, p < 0.001), and 100 lbs (8.24 vs. 5.39, p < 0.001) (Figure 3). Mean total joint space of operative hips was significantly greater than mean total joint space of non-operative hips at traction intervals of 50 lbs (6.60 vs. 5.39 mm, p < 0.001), 75 lbs (10.86 vs. 8.05 mm, p < 0.001), and 100 lbs (12.73 vs. 9.73, p < 0.001). A higher percentage of operative hips achieved all distraction thresholds, in 2-mm intervals up to 10-mm, at each traction interval (Table 1). Conclusions: In the majority of patients undergoing revision hip arthroscopy, previous arthroscopic hip surgery increases axial distractibility of the hip joint compared to the native contralateral hip at axial traction forces of 50-100 lbs. Increased axial distractibility following hip arthroscopy may be suggestive of hip instability, and can be assessed on a stress exam under anesthesia. [Table: see text]

Testo completoAbstract (sommario):
A 58-year-old man with a history of end-stage degenerative joint disease developed a postsurgical infection at the right hip 4 weeks after hip replacement surgery. He underwent surgical washout of the right hip without opening the joint capsule. Arthrocentesis returned positive for Mycobacterium fortuitum. He was started on antibiotics with the recommendation to remove the prosthesis. The prosthesis was retained. Based on antimicrobial susceptibilities, he was treated with 4 weeks of intravenous therapy using cefoxitin and amikacin and later switched to oral ciprofloxacin and doxycycline for 5 additional months. Eighteen months from his initial hip replacement surgery, he continues to do well. Joint aspiration culture is important to make a diagnosis of prosthetic joint infection (PJI) when periprosthetic culture is not available. In the absence of serious systemic or comorbid joint conditions, PJI due to M. fortuitum can be managed medically without having to remove the prosthesis or debride the joint.

Testo completoAbstract (sommario):
Although the presence of osteonecrotic bone is known to make joints more prone to infection, acute septic joint in hip osteonecrosis has not frequently been reported in adults with sickle cell disease. The clinical features at the time of admission, imaging findings suggesting the diagnosis, modes of treatment and sequelae of septic arthritis of twenty-four hip joints with osteonecrosis in patients with sickle cell disease were studied retrospectively over a 25-years period. This study evaluated also the complications, the efficiency and the risk of total hip arthroplasty in these patients. Most patients were in the third decade of life. Staphylococcus and Gram negative infection predominated. Treatment was first conservative but most of the patients needed surgery to treat infection and sequelae related to infection. A total hip arthroplasty was performed later in twenty joints. No deaths were observed, but complications occurred. Twenty of the patients in our study underwent delayed total hip arthroplasties following repeated aspirations of the joint and intravenous antibiotics. With an experienced surgical and medical team and multidisciplinary management of these patients undergoing total hip arthroplasty after hip infection, our rate of complications was acceptable.

Background: Anterior inferior iliac spine (AIIS) impingement is an important risk factor for revision hip arthroscopy. Although a morphological classification system is available, evaluating AIIS impingement with respect to joint kinematics remains a challenge. Purpose: To use computer simulation analysis to ascertain the prevalence of AIIS impingement before and after osteochondroplasty. Methods: A total of 35 joints from 30 cases (20 males and 10 females; average age: 43.3 ± 13.7 years) were analyzed. All joints had cam morphology and underwent hip arthroscopic osteochondroplasty. A three-dimensional model of each joint was constructed pre- and postoperatively. Joint kinematic simulation software (ZedHip®, Lexi, Tokyo) was used to identify the impingement point on the acetabular side and the incidence (expressed as a percentage) of AIIS impingement calculated. Radiographic and clinical evaluation was performed pre- and postoperatively. Results: AIIS impingement was observed postoperatively in six joints but preoperatively in only one joint. The rate of AIIS postoperative impingement was significantly higher than that of preoperative impingement. All impingement points were located on the inferior aspect of the AIIS apex. However, there were no significant differences between the AIIS impingement and non-impingement groups in terms of clinical outcome. Conclusion: The incidence of AIIS impingement after osteochondroplasty was 17% by computer simulation analysis. Osteochondroplasty may result in subsequent AIIS impingement.

Testo completoAbstract (sommario):
Introduction: Ischiofemoral impingement is a cause of posterior hip pain and limitation in hip extension. The compensatory motion at the lumbar spine associated with limitation in hip mobility has been associated with low-back pain, and an increase of 30% in the load at L3-L4 and L4-L5 lumbar facet joint is reported in a cadaveric study involving simulated ischiofemoral impingement. Case Presentation: A 66-year-old female developed low back pain associated with bilateral hip pain over a period of 12 years. The symptoms persisted despite 5 surgical interventions in the lumbar spine and sacroiliac joints. Impingement between the lesser trochanter and ischium, with limitation of hip extension, was identified on the physical examination and imaging studies. The patient underwent endoscopic partial resection of the lesser trochanter bilaterally. The Oswestry lumbar disability index improved from 56% before surgery to 14% at the 17-month follow-up. Impingement between the lesser trochanter and ischium should be considered in the differential diagnosis of low back pain. Conclusion: Ischiofemoral impingement should be considered as a differential diagnosis for patients with unsuccessful lumbar spine surgery. Keywords: Ischiofemoral impingement, Low back pain, Hip pain
