To elucidate the long-term effect of osteotomy upon the intraosseous pressure in osteoarthritis of the hip, pressure measurements in the femoral head and greater trochanter were performed in 22 patients before intertrochanteric osteotomy and 11.5-33.5 months later, on the occasion of removing the osteosynthesis material after the osteotomy had healed. Preoperatively the mean pressure in the femoral head was higher (35.0 mmHg) than in the greater trochanter (23.4 mmHg). At follow-up the mean pressure in the femoral head had fallen, but not significantly (0.10 less than P less than 0.20). A significant reduction in pressure (0.001 less than P less than 0.005) was found in 10 patients in whom the primary pressure was high (exceeding 35 mmHg) and in 16 patients seen at follow-up less than two years after the osteotomy (0.01 less than P less than 0.02), whereas with a longer observation period there was a tendency towards an increasing pressure. The trochanteric pressures accompanied the pressures in the femoral head, but without significant changes. No close correlation was found between intraosseous pressure and pain at rest. The operation had a good clinical effect, especially upon the pain at rest. A reduction in intraosseous hypertension may be a contributory cause, but the tendency to another increase in pressure after a long observation period indicates the possibility of a subsequent recurrence.
为阐明截骨术对髋关节骨关节炎骨内压的长期影响，对22例患者在转子间截骨术前及截骨愈合后11.5 - 33.5个月取出内固定材料时，分别测量了股骨头和大转子的压力。术前股骨头平均压力（35.0 mmHg）高于大转子（23.4 mmHg）。随访时股骨头平均压力有所下降，但差异无统计学意义（0.10 < P < 0.20）。在10例初始压力较高（超过35 mmHg）的患者以及16例截骨术后随访时间不足两年的患者中，压力显著降低（0.001 < P < 0.005），而随着观察期延长，压力有升高趋势。大转子压力与股骨头压力变化趋势一致，但无显著变化。骨内压与静息痛之间未发现密切相关性。该手术具有良好的临床效果，尤其是对静息痛。骨内高压的降低可能是一个促成因素，但长期观察后压力再次升高的趋势表明可能会复发。
