A Follow-Up Study of Clients with Chiari Pelvic Osteotomy

The purpose of this study was to investigate the relationship among coxalgia, gait pattern, activities of daily living (ADL)-functions and range of motion (ROM) of the hip joint in clients who had undergone Chiari pelvic osteotomy for osteoarthritis of the hip accompanied with acetabular displagia. Out of 56 clients who received mailed questionnaires 36 (33 females and 3 males) with a mean age of 40.1 years responded. Score measures established by the Japanese Orthopeadeic Association (JOA) were used to compare the above factors pre- and postoperatively. In addition, Spearman’s rank correlation was used for analysis of coxalgia and the clients’age for the postoperative phase. The mean total JOA score for the postoperative period was significantly higher than that for the preoperative phase. The mean total score for coxalgia and gait pattern for the postoperative phase was significantly higher than that for the preoperative phase. However, the mean total JOA score ROM of the hip in the postoperative phase was significantly lower than that for the preoperative phase. The mean total JOA score pre- and postoperative ADL-functions showed no significant difference. Although a correlation was present between coxalgia and the clients’age scores, there was no correlation between coxalgia and postoperative phase scores. These findings indicate that coxalgia increases with client’ advancing age. Therefore, such clients should be advised to reduce their ADL-functions and a home exercise program should be implemented.
