Abstract
Hip motion and spine motion in forward bending are related closely. In coxarthrosis patients, limitation of hip motion is though to affect spine motion in forward bending. The purpose of this study was to evaluate the correlation between the motion of lumbar spine and hip with osteoarthrosis. Subjects were 164 female coxarthrosis patients (44 to 88 years, mean age: 62 years) who underwent total hip arthroplasty. The range of motion in hip and lumbar spine was measured in preoperative lateral radiographs (neutral position and sitting forward bending position), and evaluated according to age. The range of hip motion generally decreased for osteoarthritis. The range of lumbar motion correlated with age negatively. These results suggest that, in middle aged patients, because of less degenerative change of lumbar spine, limited of hip motion can be compensated with lumbar spine motion. In elderly patients, because of degenerative change of lumbar spine, limited lumbar spine motion is compensated with hip of osteoarthrosis.
