Abstract: 【Abstract】〓Objective〓To observe the effect of proximal femoral nail antirotation (PFNA) with salmon calcitonin on the treatment of unstable intertrochanteric fractures in the elderly. Methods〓Ninety elderly patients with unstable intertrochanteric fracture were chosen and divided into 3 groups (A, B and C). The patients in group A received open reduction with DHS, and group B got closed reduction with PFNA. The patients in group C underwent closed reduction and salmon calcitonin after the operation. The clinical efficacy in and after the treatment were compared between three groups. Results〓The patients in group B got a better effect in and after the operation and had less complications than in group A. Patients in group C showed less time in the fracture restoration than those in group B (P<0.05). Conclusion〓PFNA fixation for unstable intertrochanteric fractures in the elderly has the better clinical effect. Salmon calcitonin is helpful to union of fracture after PFNA fixation.

摘要： 【摘要】〓目的〓观察闭合复位防旋近段股骨髓内钉(PFNA)内固定联合早期使用降钙素治疗高龄不稳定型股骨转子间骨折的临床疗效。 方法〓选取90例高龄不稳定性股骨转子骨折患者分别给予切开复位DHS髓外固定(A组)、闭合复位PFNA内固定(B组)和闭合复位PFNA+鲑鱼降钙素治疗(C组),观察比较3组术中情况、术后恢复情况和术后并发症情况。结果〓B组比A组在术中情况及术后恢复上均有优势;而C组相对于B组,其开始负重锻炼的时间和骨折愈合时间显著较短;B组术后并发症发生显著少于A组(P均<0.05)。结论〓闭合复位PFNA内固定能够获得更好的恢复效果,配合降钙素能够有效缩短恢复时间。
