Abstract
The object of this study was to elucidate the post-Operative recovery process of the patients who had experienced modified Chiari pelvic osteotomy at Kanazawa Medical University Hospital. We periodically evaluated thirty one patients whom we were able to follow up more than three months. Test items were muscle strength, range of joint motion, pain, ambulatory ability and activities of daily living. The involved joints were thirty four in total.
The each test data of pre and post operation were statistically examined and the results revealed remarkable improvements in muscle strength including muscle endurance and pain relief for a period of one to two years. Ambulatory ability also remarkably improved. The average clinical score of osteoarthritis of the hip joint standardized by Japanese Otrhopedic Surgery Association was improved from 71.5 at pre-operation to 90.6 at post-operation for a period of one year. The reason of pain relief might have been due to the reduction of stress by means of surgical re-construction of abnormal hip joints, and prevention of excess lateral movements of the head of the femur by means of strengthening of gluteus medius. Therefore, joint-play movement disorder which is one of the joint dysfunction may be a major factor to cause the hip joint pain.
