空心加压螺纹钉内固定与人工全髋关节置换术治疗股骨颈骨折的疗效分析

The effect of Ao hollow compression screw thread nail internal fixation and total hip replatemeat treatment of femoral neck fracures

目的比较空心加压螺纹钉与人工全髋关节置换术治疗老年股骨颈骨折的疗效。方法将64例46岁以上股骨颈骨折患者分为两组,分别行AO空心加压螺纹钉内固定与人工全髋关节置换术,术后随访8～42个月,平均30.2个月。结果根据Harris定义的Harris评分系统,进行临床评估。内固定组优良率87%,全髋置换组94%。全髋置换组总体疗效好于内固定组。结论 AO空心加压螺纹钉内固定与人工全髋关节置换都是治疗老年股骨颈骨折的有效方法,两者各有不同的适应证。在技术力量和患者经济状况及全身情况许可的条件下,施行人工关节置换术可取得更优良的临床效果。

Objective To compare curative effect of AO hollow compression screw thread nail internal fixation with to tall hip replacement （THR） to treat old age femoral neck fractures. Methods 64 cases of 46 years above of femoral neck fractures were divided two groups adopted AO hollow compression screw thread nail internal fixation with THR, after operation followed up from 8 months to 42 months, average 30. 2 months. Re- stilts curative effect was assessment according to patient chief complaint, joint function and X ray find- ing. Internal fixation group fine nessrate was 87% THR group was 94%. The curative effect of THR group was better than internal fixation group. Conclusion AO hollow compression screw thread nail internal fixation with THR is the effective method to treat old age femoral neck fractures. There was different indication. There was more superior clinical effect on prosthetic replacement for joint in technical force and patiente eonomic status and total body information premised.
