Fractures occurring at or near the distal tip of a hip prosthesis with stable femoral stem (Vancouver type-B fractures) are associated many complications because inherently unstable fracture pattern. Locking compression plates use screws that lock into plate allowing multiple points unicortical fixation. Such fixation may lower risk damage to cement mantle during treatment periprosthetic fracture. The purpose this study was analyze clinically and radiographically group patients Vancouver...
Impaction grafting is controversial in the presence of segmental and cavitary acetabular defects requires use supplemental devices to close defects. This approach, however, would allow treating combined deficiencies that could not be managed with impacted cancellous bone alone. We raised following two questions: (1) What survival rate patients reconstructed metal mesh, impaction a cemented cup (2) can mesh prevent migration? evaluated 23 uncontained revision hip arthroplasty. Preoperative...
Bone allografts can store and release high levels of vancomycin. We present our results a two-stage treatment for infected hip arthroplasty with acetabular femoral impaction grafting using vancomycin-loaded allografts. treated 29 patients (30 hips) by removal the implants, meticulous debridement, parenteral antibiotic therapy second-stage reconstruction vancomycin-supplemented impacted bone standard, cemented Charnley component. The mean follow-up was 32.4 months (24 to 60). Infection...
Abstract Introduction: Periacetabular osteotomy (PAO) has a recognized success for the treatment of hip dysplasia with lateral center-edge angle (LCEA) ≤20°. In cases mild or so-called ‘borderline’ (LCEA>20°;<25°), there is no clear consensus on definitive treatment, which either arthroscopy PAO were proposed. We aimed to report radiologic and functional outcomes patients treated PAO. Methods: retrospectively analyzed 123 undergoing between 2016-2023, 73 (94.6% females)...
Objective: To design and evaluate a novel CT-firee image-guided surgical navigation system for assisting placement of both acetabular femoral components in total hip arthroplasty (THA).Materials Methods: The methodology this paper is conceptually based on our previous work CT-free cup placement. For component placement, two patient-specific reference coordinate systems are first defined: One the pelvis, so-called anterior pelvic plane (APP) concept, one femur, using center head, posterior...
Background Cancellous bone can act as a delivery vehicle for vancomycin without impairment of graft incorporation. However, local and systemic antibiotic levels, biological activity vancomycin, interaction with antibiotic-loaded cement, also nephrotoxicity these composites have not yet been studied clinically.Material methods Blood, drainage urine samples 20 consecutive patients undergoing revision total hip arthroplasties impaction grafting technique utilizing 1 g per femoral head were...
We reviewed the clinical and radiological results of 131 patients who underwent acetabular revision for aseptic loosening with impacted bone allograft a cemented component. The mean follow-up was 51.7 months (24 to 156). post-operative Merle D'Aubigné Postel scores were 5.7 points (4 6) pain, 5.2 (3 gait 4.5 (2 mobility. Radiological evaluation revealed migration greater than 5 mm in four components. failure matched failure. Asymptomatic radiolucent lines observed 31 426 areas assessed (7%)....

Background The diagnosis of a suspected infected prosthesis is often difficult, but important for the choice treatment. Even at surgery, it not easy to assess whether or not—even though this may be surgical procedure.Patients and methods We assessed sensitivity, specificity, predictive value, reliability results analysis frozen sections from samples tissues taken during revision hip surgery 136 probably prostheses. Samples were analyzed immediately sections, processed on routine basis later,...
The sensitivity and specificity to detect periprosthetic infection of the different methods have been questioned, no single laboratory test accurately detects before revision arthroplasty.We asked whether preoperative C-reactive protein (CRP) interleukin-6 (IL-6) could lead similar sensitivity, specificity, predictive values as our previous results obtained with intraoperative frozen section (FS) in total hip arthroplasty (THA).We prospectively followed 69 patients who had undergone THA for...

Synovial quantification of C-reactive protein (SCRP) has been recently published with high sensitivity and specificity in the diagnosis periprosthetic joint infection. However, to our knowledge, no studies have compared use this test intraoperative frozen section, which is considered by many be best now available.We asked whether SCRP could lead comparable sensitivity, specificity, predictive values as section revision total hip arthroplasty.A prospective study was performed including 76...
Background: The purpose of this study is to evaluate the clinical outcomes, radiological degenerative progression and joint preservation rate in a series patients with Femoroacetabular Impingement (FAI) treated hip arthroscopy at minimum follow-up 7 years.The predictive factors for total arthroplasty (THA) requirement were analyzed.Materials methods: Between February 2008 2009, 42 consecutive due FAI syndrome included.There 15 women 27 men an average age 38 years (range 23 56 years).The...
We explored the role of vancomycin-supplemented cancellous bone allografts in hip revision surgery. evaluated incorporation these 18 pigs' radiographs, histology, and immunohistochemistry. High-quality histologic examination, immunologic expression metalloproteinase-13 transforming growth factor-beta 2 indicated vancomycin did not considerably affect graft incorporation. Elution, bioactivity, nephrotoxicity were subsequently tested 20 patients who underwent reconstruction with this method....
Introduction: Core decompression (CD) with or without the addition of autologous bone graft (CDBG) is currently most widely accepted treatment for hip osteonecrosis in stages pre-collapse. The use marrow mesenchymal stem cells (CDSC) emerging as a promising biological alternative. We sought to determine total arthroplasty (THA) conversion rate patients treated CD, CDBG CDSC. Material and methods: Between 1996 2012, 97 cases were evaluated 72 patients: 47 CD cases, 34 CDGB 16 CDSC cases. mean...
To plan for the continuance of elective hip and knee arthroplasty during a resurgence or new wave COVID-19 infections.A systematic review was conducted using terms "COVID-19" "SARS-Cov-2" "second wave". No relevant citations were found to inform on recommendations plan. Therefore, an expert panel European Hip Society Knee Associates formed provide recommendations.Overall, consider three phases; first wave, preparation next wave. International national policies will drive most management. The...
