The purpose of the paper was to investigate the natural course of the hip in sixtytwo patients with cerebral palsy. We evaluated the postoperative results of the dislocated or subluxated hips in twelve patients.
The results were as follows;
i) non-operative cases
1) Dislocated or subluxated hips were found in nineteen percents of 124 aips.
2) Most of the hips in cerebral palsy had the abnormal neck-shaft angle, anteversion angle, CE and Sharp angle.
3) Five patients of twenty-three that followed-up more than three years, progressed to dislocation or subluxation.
ii) operative cases
1) Reposition of the dislocated hip was not achieved in one case and recurrence of the dislocation occured in two cases.
