In successive series of displaced subcapital femoral neck fractures in the elderly, we operated on 75 cases with three Gouffon screws, 94 with three Mecron screws, and 75 with two von Bahr screws. Redisplacement within 3 months occurred in 20 Gouffon cases, 11 Mecron cases, and 12 von Bahr cases. Poor reduction contributed to the failures in all the groups. Although the reduction results in the three groups were similar, the Mecron group had better fixation and better social recovery than the Gouffon group. We concluded that, in addition to good reduction of the fracture, solid screws also contributed to the stability of the bone-implant construct.
在老年移位性股骨颈基底部骨折的连续系列病例中，我们用3枚古丰螺钉对75例患者进行了手术，用3枚麦克龙螺钉对94例患者进行了手术，用2枚冯·巴尔螺钉对75例患者进行了手术。3个月内出现再移位的情况，古丰组有20例，麦克龙组有11例，冯·巴尔组有12例。复位不佳是所有组治疗失败的原因。虽然三组的复位结果相似，但麦克龙组的固定效果和社会恢复情况比古丰组更好。我们得出结论，除了骨折的良好复位外，坚固的螺钉也有助于骨植入物结构的稳定性。
