The purpose of this retrospective study was to review the outcome of THA in the treatment of bilateral hip ankylosis of different causes; surgical, septic or spontaneous. 20 THA procedures in 10 patients were included in the study, 5 males and 5 females all had bilateral fusion. Previous pathologies included: ankylosing spondylitis, AVN, septic arthritis and surgical arthrodesis. Flexion deformity ranged (10°-45°). Shortening as compared to normal anatomy was up to 6 cm and leg length discrepancy (LLD) ranged from 1 cm to 2.5 cm. Most unified X-ray finding was massive osteophytes formation with 3 patients showing severe narrowing of the femoral canal. Operative time averaged 147 minutes (70–210) and lateral approach was used in all patients, anesthesia was general with only 3 undergoing spinal anesthesia.Introduction
