Abstract CASE DESCRIPTION A 9-year-old 37-kg sexually intact male snow leopard (Panthera uncia) with no history of lameness but radiographic evidence of right femoral subluxation and flattening of both femoral heads, 2 juvenile (< 1 year old) 25-kg sexually intact male cheetahs (Acinoynx jubatus) with unilateral hind limb lameness resulting from trauma, and an 11-year-old 110-kg sexually intact female Amur tiger (Panthera tigris altaica) with a 2-year history of left hip joint osteoarthritis were examined. CLINICAL FINDINGS No clinically relevant clinical findings other than hip joint problems were identified. All 4 felids underwent staged bilateral (snow leopard) or unilateral (cheetahs and tiger [Panthera tigris]) total hip arthroplasty (THA). TREATMENT AND OUTCOME In the snow leopard, both femoral THA components were found to be luxated 1 year after surgery. Treatment consisted of autogenous corticocancellous rib graft augmentation of the dorsal acetabular rims and synthetic suture capsulorrhaphies. The snow leopard lived for an additional 4 years with no additional THA-related complications. In the other 3 animals, catastrophic complications (luxation in the cheetahs and femoral fracture in the tiger) occurred shortly after THA. The THA implants were removed, and excision arthroplasty was performed. Long-term outcomes were good in all 3. CLINICAL RELEVANCE Findings underscore the challenges associated with THA in large nondomestic felids. Given the high risk for early catastrophic failure as a result of luxation or fracture, plans must be made and resources must be available in case revision surgery or implant removal with excision arthroplasty becomes necessary.

Background. Conservative treatment options for hip dysplasia and hip dislocation in early childhood allow for good results in cases of a timely diagnosis. The preferred treatment option for patients with hip dislocation in adulthood is total hip joint replacement. The shortening osteotomy, proposed by T. Paavilainen, allows the surgeon to restore the difference in the lengths of the lower extremities during arthroplasty of the hip joint. However, according to the results of the Paavilainen technique, as presented by Russian orthopedic surgeons, the problem of nonunion of the greater trochanter fragment with the diaphysis of the femur remains unresolved, as evidenced by a massive group of clinical cases. Aim. The aim of this study was to identify factors affecting the consolidation of bone fragments after osteotomy of the greater trochanter, according to T. Paavilainen, during total hip arthroplasty and evaluate their significance after fixation with cerclage screws in comparison with a special trochanteric fork-plate. Materials and methods. The present study includes 208 cases that were treated at the Russian Scientific Research Institute of Traumatology and Orthopedics named after R.R. Vreden from 2003 to 2019 using various fixation techniques of the greater trochanter fragment. Patients were divided into two groups depending on their type of fixation. The quality of consolidation of a greater trochanter fragment with the femur was assessed during a follow-up period of six months or longer. The fragment of the greater trochanter was divided into the part that was not in contact with the diaphysis, or A, and the part that was in contact with the diaphysis, or B. We assessed the effect of the absolute value of the contact between fragments, the B/A ratio, the distance between the points of insertion of the screws into the diaphyseal part of the femur, the quality of the bone by the modified Barnet-Nordin index, and the history of previous surgical interventions on this joint on the consolidation. Results. When the part of the greater trochanter was in contact with the diaphysis of the femur (B) was less than 3.5 cm, the risk ratio of nonunion of the greater trochanter fragment with the diaphysis of the femur increased. Also, a significant factor is the index of the contact of the greater trochanter fragment (B/A less than 1) with the diaphysis of the femur using the T. Paavilainen technique. In addition, the presence of surgical intervention in the hip joint history significantly increases the relative risk (RR) of nonunion of the greater trochanter fragment with the diaphysis of the femur with this method of shortening osteotomy of the femur. Conclusion. In the absence of timely diagnosis and conservative treatment of children with hip dislocation, reconstructive-plastic techniques on the hip joint do not allow the achievement of proper results and increase the complexity of total hip arthroplasty. According to the results of this study, the absolute value of the contact between fragments (B), the index of the greater trochanter contact with the diaphysis of the femur, and the history of previous surgical intervention on this joint are objective tools for the prognostic assessment of the probability of fragment unions during total hip arthroplasty with the T. Paavilainen technique.

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.

Introduction: The Chiari pelvic osteotomy (CPO) has been recommended as a salvage procedure to improve head coverage in case of hip joint incongruence in paediatric hip disease. In this study, we aimed to assess the long-term results of CPO for severe Legg-Calvé-Perthes disease (LCPD). Methods: A total of 39 patients who underwent a CPO at our department between 1995 and 2010 were prospectively followed both radiologically (Stulberg classification) and clinically (Harris Hip Score [HHS], conversion into total hip arthroplasty). In this study, we retrospectively reviewed the cases of 12 hips (12 patients, 3 girls, 8 left hips) treated by CPO for severe LCPD (Catterall grade 3 or 4) with hip joint incongruence. Mean follow-up was 14.0 (range 7.6–21.3) years. Results: Mean age at surgery was 10.2 (range 8.2–17.8) years. Additional femoral osteotomy was performed in 8 patients. A good radiological result (Stulberg I or II) was achieved in 2 patients, a fair result (Stulberg III) in 4 patients, and a poor outcome (Stulberg IV or V) in 6 patients. Mean postoperative HHS averaged 93 (range 65–100) points. An excellent functional outcome (HHS 90–100 points) was achieved in 9 patients. No patient underwent total hip arthroplasty during follow-up. Postoperative limb-length discrepancy was found in 3 patients. Conclusions: CPO for severe LCPD with hip joint incongruence resulted in good long-term clinical outcome in about ⅔ of our patients after a mean of 14 years. Our results suggest that CPO can still be considered as a salvage joint-conserving procedure in this selected group of younger patients.

Abstract Background Total nucleated cell (TNC) count and differential are used to classify joint effusions as inflammatory or noninflammatory. Further diagnostic evaluation and management is contingent on this classification. TNC count can be measured by automated analyzers or by manual assessment using a hemocytometer. Studies have raised concerns regarding the accuracy of TNC counts measured by automated instruments, particularly in the setting of joint arthroplasty. The objective of this study was to determine whether metallosis, a complication of total hip arthroplasty in which metal debris accumulates in periprosthetic tissues and synovial fluid, is associated with inaccurate TNC counts in synovial fluid. Methods We compared the accuracy of cell counts measured by the Sysmex XN-1000 and Beckman Coulter Iris iQ200 with the gold standard of manual assessment using a hemocytometer in synovial fluid from patients with suspected metallosis and in fluid obtained from controls from patients with native joints and a history of arthroplasty for other indications. Results TNC counts produced by automated analyzers were associated with increased levels of discordance (relative to manual counts) in patients with metallosis. Metallosis was not associated with increased levels of discordance for RBC counts or WBC differentials. The Sysmex XN flagged all but 1 metallosis sample for manual verification of the results. Conclusions Automated methods are generally reliable for analysis of synovial fluid. TNC counts can be inaccurate in the context of metallosis following total hip arthroplasty. Laboratories should correlate automated cell counts with a microscopic assessment of the specimen, as recommended by instrument manufacturers.

The risk of periprosthetic joint infection from hematogenous bacterial seeding is increased in patients undergoing dental procedures that facilitate the development of bacteremia. We herein report the case of a patient without a history of dental procedures who suffered from an acute metastatic infection of a hip prosthesis by the oral bacterium Streptococcus mutans 18 months after undergoing revision total hip arthroplasty. The patient was successfully treated by two-stage revision surgery. It is important to realize that the efficacy of antibiotic prophylaxis against joint infections has not yet been convincingly proven. As a result, optimal dental hygiene and regular dental visits may be more important than antibiotic prophylaxis for maintaining joint health. Therefore, orthopedic surgeons should educate patients with joint prostheses about good oral health.
