Arthrodesis for failed arthroplasty of the hip.

The results of Girdlestone arthroplasty after failure of total hip arthroplasty have been found to be functionally poor in the physiologically young patient. The authors have evaluated 14 patients who were treated by hip arthrodesis following repeated failed arthroplasty. The average number of previous procedures was 2.6. Seven were infected prior to arthrodesis. A modified A.O. technique was used in all cases and was followed by hip spica immobilization. The average age of the patients was 38 years. All but one were men. Thirteen of the patients healed their arthrodesis primarily. Pain relief was excellent and most patients were able to return to their original jobs, in contrast to the results in patients with Girdlestone arthroplasty. Osteotomy or arthrodesis is preferred to total hip arthroplasty in the young, active patient with unilateral osteoarthritis. Arthrodesis is also possible and has a high rate of functional success after failed arthroplasty, infected or noninfected.
