BACKGROUND Osteoarthritis of the hip is five to ten times more common in white people than in Chinese people. Little is known about the true prevalence of femoroacetabular impingement or its role in the development of osteoarthritis in the Chinese population. A cross-sectional study of both white and Chinese asymptomatic individuals was conducted to compare the prevalences of radiographic featu...

The purpose of this study was to describe radiological fracture patterns of the acetabulum sustained after fatal small aircraft aviation accidents, aiming at facilitating a better understanding of trauma mechanisms in a forensic setting. Postmortem conventional radiographs or CT scans of 29 victims of 20 small aircraft aviation accidents were analyzed for skeletal acetabular trauma. Among the 2...

INTRODUCTION: Polycarbonate urethane (PCU) has been investigated as a candidate bearing material for total acetabular replacement and unicondylar knee replacement [1-4], and is currently being used in a pliable acetabular component (AIC Acetabular Buffer: Active Implants Corp., Memphis, TN). However, the susceptibility of PCU to post-irradiation aging is not yet fully understood. Furthermore, d...

A retrospective review was conducted at an academic trauma center to determine whether fracture characteristics or aspects of native anatomy are predictive of early failure after fixation of posterior wall acetabular fractures. A chart review of posterior wall acetabular fractures treated from 2004 to 2009 yielded the study group that met the inclusion criteria. The study group included 18 cons...

Periacetabular osteotomy (PAO) is a complex surgical procedure to restore acetabular coverage in the dysplastic hip, and the amount of acetabular rotation during PAO plays a key role. Using computational simulations, this study assessed the optimal direction and amount of the acetabular rotation in three dimensions for a patient undergoing PAO. Anatomy-specific finite element (FE) models of the...

We have reviewed 70 Harris-Galante uncemented acetabular components implanted as hybrid hip replacements with cemented stems between 1991 and 1995 in 53 patients whose mean age was 40 years (19 to 49). The mean follow-up was for 13.6 years (12 to 16) with no loss to follow-up. We assessed the patients both clinically and radiologically. The mean Oxford hip score was 20 (12 to 46) and the mean H...

PURPOSE To assess the short-term outcome of cementless total hip arthroplasty involving an autograft of the femoral head in Japanese patients. METHODS Cementless total hip arthroplasty with autogenous bone block grafting was performed on 18 hips in 15 patients with marked acetabular dysplasia. The resected femoral head was used as a graft for the superior-lateral region of the true acetabulum...

We present 2 cases of cam/pincer combined femoroacetabular impingement treated arthroscopically with labral debridement, acetabuloplasty, and femoral head recontouring. In both cases there was essentially no evidence of osteoarthritis of the hip. However, in both cases raised exostoses were evident on the anterolateral femoral neck in the region that commonly comes into contact with the acetabu...
