1. Subtrochanteric osteotomy performed at the time of primary hip arthrodesis has been helpful in lowering the rate of pseudarthrosis.
2. The use of a single hip spica in conjunction with osteotomy at the time of arthrodesis has not been harmful.
3. The single hip spica has allowed the earlier ambulation of the patient and in general has been successful in maintaining the desired position of the limb.
4. When possible, immobilization of the superior fragment by internal fixation and grafts is advised.
