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.
对30个髋关节患有股骨头坏死的25例患者进行了转子间内翻截骨术后平均11.6年的放射学研究。术前仅见Meyers分级的2期和3期。随访结果可分为4组。最好的情况是骨坏死在6至9年内重建，而小梁在2至4年内开始重新排列。最坏的情况是观察到在没有骨反应的情况下迅速破坏。截骨术后骨坏死区域外的骨对变化情况的反应能力与长期结果相关。这可能表明即使在坏死区域外也存在全身性骨病。
