空心拉力螺钉固定并植入带孔同种异体腓骨治疗中青年股骨颈骨折的临床观察

摘要

目的：探讨空心拉力螺钉固定并植入带孔同种异体腓骨治疗中青年股骨颈骨折的疗效。方法：两枚空心拉力螺钉与带孔同种异体腓骨呈正三角形固定治疗中青年股骨颈骨折。结果：术后63例获随访患者，骨折均愈合，其中有5例出现股骨头坏死，3例坏死灶得到修复，2例患者没被修复，但关节面保持完整没塌陷。结论：2枚空心拉力螺钉固定并植入带孔同种异体腓骨治疗中青年股骨颈骨折具有坚强固定，改善股骨头血运的优势，有助于提高股骨颈骨折愈合率，降低股骨头坏死率及股骨头坏死塌陷率。%Objective:To investigate the curative effect of cannulated lag screw fixation combined allogeneic fibular with holes implantation in the treatment of young and middle-aged femoral neck fracture.Method:The young and middle-aged patients with femoral neck fracture were treated with two cannulated lag screw and fixed a positive triangle with allogeneic fibular with holes.Result:63 patients were followed up after surgery,the fractures were all healed.There were 5 cases of femoral head necrosis,3 cases of necrotic foci repaired,2 patients of no repaired,but the joint surface remained intact.Conclusion:Two cannulated lag screw fixation combined allogeneic fibular with holes implantation for the treatment of young and middle-aged femoral neck fracture have advantages of strong fixation and improving the blood supply of the femoral head,it is helpful to improve the healing rate of femoral neck fracture,reduce the rate of femoral head necrosis and rate of femoral head necrosis collapse.
