One hundred thirty-one patients (135 fractures) who sustained an intertrochanteric fracture were assigned randomly to treatment with either a sliding hip screw or an intramedullary hip screw and followed up prospectively. In patients with unstable intertrochanteric fractures, the intramedullary device was associated with 23% less surgical time and 44% less blood loss; however, use of the intramedullary hip screw in patients who had a stable fracture pattern required 70% greater fluoroscopic time. Intraoperative complications occurred exclusively in patients in the intramedullary hip screw group. There were no differences in the rates of functional recovery between the two fixation groups.
131例(135处骨折)发生转子间骨折的患者被随机分配接受动力髋螺钉或髓内髋螺钉治疗,并进行前瞻性随访。在不稳定转子间骨折患者中,髓内器械的手术时间减少23%,失血量减少44%;然而,在骨折类型稳定的患者中使用髓内髋螺钉需要的透视时间增加70%。术中并发症仅发生在髓内髋螺钉组患者中。两组固定方式的功能恢复率没有差异。
