title: Middle and long-term results of flexion osteotomy for avascular necrosis of the femoral head.
abstract: The authors present the results of 19 flexion osteotomies performed in cases of avascular necrosis of the femoral head and followed up after an average of 8 1/2 years. Significant clinical improvement was achieved in 85% of the patients. The radiographic picture is not quite as positive, but only 26% of the patients developed severe degenerative arthritis. The authors therefore consider this technique to be a valid alternative to immediate prosthetic replacement in selected patients.
