28 hips of 22 patients with highly dislocated coxarthrosis were reviewed to inveshgate the state of ADL disturbance. Patients were divided into two groups according to the radiological degree of dislocation; a group in which articulation was found between the iliac wall and femoral head (group 1), and a group in which the femoral head was buried in the gluteal muscles (group 2).
Comparing the JOA score between the two groups, pain in group 1 was more severe than that of group 2. However, there were no differences in walking ability, range of motion and ADL disturbances, walking ability was more disturbed in unilateral than in bilateral dislocation. The main ADL problens consisted of standing up, going upstairs, squatting down and cutting toe nails, and these symptoms were progressive with increasing age.
