Abstract/Text
BACKGROUND: We conducted a nationwide epidemiologic study regarding hip osteoarthritis (OA) in Japan, and a previous report found these patients to be unique in comparison to Caucasians. This report focused on the data regarding each hip joint, and the involvement of acetabular dysplasia with hip OA was analyzed.
METHODS: Seven hundred twenty OA hips were examined. Sixty-five joints with osteonecrosis of the femoral head and 215 non-OA contralateral joints of the unilateral patients were examined as controls. The revised system of stage classification for hip OA of the Japanese Orthopedic Association (JOA) was used according to the reproducibility in order to ensure reliable data from the multiple institutions. The acetabular dysplasia indexes were also chosen according to the reproducibility and measured in the radiograph of bilateral hip joints. The clinical score was assessed using the JOA scoring system. The relative risk of the grade of acetabular dysplasia indexes for hip OA was calculated as the odds ratio and the 95% confidence interval.
RESULTS: The stage of the OA joints deteriorated with increasing age. The clinical scores also decreased. The grade of the acetabular dysplasia indexes of the OA joints was significantly higher than that of the control joints. Each index of acetabular dysplasia demonstrated significantly increased odds ratios for hip OA. Among the OA joints, the deterioration of the OA stage was found to be significantly associated with an increasing grade of acetabular dysplasia. The odds ratio for OA deterioration in the acetabular dysplasia index was also obtained. The joints of females tended to have a higher grade and prevalence of acetabular dysplasia than those of males.
CONCLUSIONS: These findings confirmed a high prevalence of acetabular dysplasia in hip OA joints in Japan. Acetabular dysplasia was one of the most important factors associated with hip OA.

Abstract This study examined validity indices of the Trendelenburg test as a measure of hip abductor muscle performance (adduction of pelvis-on-femur [P-O-F]) when identifying subjects with and without hip joint osteoarthritis (OA). Muscle performance of the hip abductor muscles was obtained in standing by using the P-O-F position measured with a goniometer and in supine using a handheld dynamometer (HHD) and a manual muscle test (MMT). We studied 20 healthy adults (10 men and 10 women) and 20 adults (10 men and 10 women) with radiographically documented hip joint OA. Indices including sensitivity, specificity, and positive likelihood ratios examined values obtained from the P-O-F position and the MMT when used to identify subjects with and without hip joint OA. Sensitivity of the P-O-F position for identifying subjects with hip joint OA was 0.55, and specificity was 0.70, yielding a positive likelihood ratio of 1.83. Sensitivity of normalized hip abductor MMT strength for identifying subjects with hip joint OA was 0.35 and specificity was 0.90, yielding a positive likelihood ratio of 3.5. Based on validity information from the present study, the Trendelenburg test (P-O-F angle) is not useful in identifying subjects in the early stages of hip joint OA.

Abstract/Text
We followed long-term osteoarthritis of the hip clinically and radiographically in 38 patients (47 hips) finally reaching an advanced or terminal stage for more than 10 years. The relation between various measured parameters and disease progression and osteophyte formation was analyzed. By multivariate analysis, the clinical outcome of osteoarthritis of the hip could be correctly predicted in 91.5% of cases. In the cases in which initially the slope of the acetabular roof was not steep, the greater trochanter was low, and the cranial joint space was narrow, good roof osteophyte formation was well recognized. The cases with good roof osteophyte formation were characterized by preserved roundness of the femoral head, no shortening of the femoral neck, no lateralization of the femoral head, unchanged cranial joint space, and no worsening of pain at the final follow-up.
