Abstract
OBJECTIVE: To assess the leg-length inequality in patients with hip osteoarthrosis (OA) and to evaluate a possible association between the length disparity and side of OA. DESIGN AND PATIENTS: Weight-bearing radiographs of 100 consecutive patients undergoing arthroplasty for primary OA were examined and measured for inequality of leg length, pelvic tilt and severity of OA. RESULTS: The radiographic results showed that preoperatively OA occurred more frequently in the hip of the longer (84%) than the shorter (16%) leg. However, the development of OA did not show a linear relationship with the magnitude of leg-length inequality. CONCLUSION: As hip OA occurred more frequently in the longer leg the authors speculate whether leg-length inequality might predispose to OA in the hip of the longer leg.
