Abstract

We performed conversion of ankylosed hips to total hip arthroplasty (THA) for 4 patients during the period between September, 1999 and February 2000. Their ages ranged from 50 to 65 years and the duration of fusion prior to THA ranged from 17 to 51 years. The patients consists of two men and two women. The causes of ankylosis were tuberculous arthritis (two patients) and osteoarthritis (two patients). In our cases, the indications for conversion to THA were disabling pain in the low back and knee, and disability of ADL. Relief of preoperative pain vas obtained in all patients, and their gait improved. All patients were satisfied with the results of conversion to THA.
