Leg length discrepancies are caused by inclinatio pelvis and scoliosis as well as joint deformity like shortening in bone length or hip joint dilocation. They are considered to play a causative role in mechanically inducing poor posture, leading the upright posture to be flexed bilaterally. For the past two and half years, we measured leg length discrepancies in a supine position and torsional inclination of pelvis and hip in a prone position of a total of 809 patients who had admitted to our hospital. In this study, the incidence of leg length discrepancies was examined and the causative factors were analyzed. It was found that the incidence was extremely high, and the shortening in right leg was especially prominent. With increasing ages, the shortening in left leg was found to become prominent, and that in both legs was also observed in some cases. Leg length discrepancies were found to be caused mainly by architectural changes such as muscle or joint contracture in pelvis or lower extremities and subluxation, rather than morphological changes. This study also introduced the analysis of dorsal posture in a prone position.
