Abstract
1. Arthrodesis of the hip is satisfactory provided a good range of knee flexion is preserved.
2. The hip is best arthrodesed in its deformed position, and the deformity corrected by a high femoral osteotomy. Knee range can readily be retained by treating the patient on traction for the first six weeks instead of using plaster.
3. Thirty-three arthrodeses were attempted without osteotomy. Only thirteen were satisfactory. Even our best method without osteotomy gave sound fusion in only seven out of ten cases.
4. In a series of twenty-three unselected cases in which osteotomy was performed in addition to other methods, fusion occurred in twenty-two.
