[Long-term results following intertrochanteric varus osteotomy in aseptic femur head necrosis in the adult].
25 patients suffering from femoral head necrosis in 30 hip joints were radiologically studied for an average of 11.6 years following intertrochanteric varus angulation osteotomy. Preoperatively only stages 2 and 3 according to Meyers were seen. The follow-up results could be distributed into 4 groups. At best the osteonecrosis was reconstructed within 6 to 9 years while the trabeculae started to become rearranged within 2 to 4 years. At worst, rapid destruction in absence of bony reaction was observed. The ability of the bone outside the osteonecrosis to react to changed circumstances following angulation osteotomy correlates with long-term results. This may indicate a general osteopathy even outside the necrotic area.
