Thirty-eight patients with unstable trochanteric fractures of the femur were treated with Dimon-Hughston displacement osteotomy and cement augmentation at the fracture site. Of these patients 76 per cent had excellent and good results after an average follow-up of 3.7 years (range 2-5 years). Late complications occurred in six hips. These included non-union at the trochanteric fracture, protruding pin, partial destruction of the femoral head, subcapital fracture of the femoral neck, and avascular necrosis of the femoral head. All complications occurred late (1 year after surgery) and were related to inappropriate placement and excessive amount of cement, together with inadequate new bone formation. The augmentation of cement provided early stability for early mobilization in these elderly patients. However, when improperly used, late complications can occur.
38例股骨转子间不稳定骨折患者接受了迪蒙-休斯顿移位截骨术，并在骨折部位进行骨水泥强化。这些患者中，平均随访3.7年（范围2 - 5年）后，76%的患者获得了优良结果。6髋出现了晚期并发症。这些并发症包括转子间骨折不愈合、钢针突出、股骨头部分破坏、股骨颈头下骨折以及股骨头缺血性坏死。所有并发症均发生在晚期（术后1年），与骨水泥放置不当、用量过多以及新骨形成不足有关。骨水泥强化为这些老年患者早期活动提供了早期稳定性。然而，使用不当会发生晚期并发症。
