目的：探讨股骨转子间骨折及股骨颈骨折内固定失效后行人工髋关节置换术治疗效果。方法：钢板组及动力髋螺钉组患者均给予人工髋关节置换术治疗，记录两组患者治疗后骨水泥评级情况及髋关节功能恢复情况，给予统计学分析后得出结论。结果：AO加压空心螺钉组骨水泥评级大多处于B级（74.00%），而动力髋螺钉组骨水泥评级大多属于C级（62.00%）；两组患者治疗前Harris评分对比结果无显著差异（P>0.05）；经治疗后两组Harris评分情况均较治疗前显著改善（P<0.05），但两组改善效果对比无显著差异（P>0.05）。结论：临床医生应根据患者实际情况选择合适的内固定材料，从而获得更为满意的临床疗效及预后，为内固定失效实施人工髋关节置换术治疗提供有力条件。%Objective: Discussion intertrochanteric fracture fixation failure and femoral neck fracture underwent hip replacement surgery treatment. Methods: Plate group and dynamic hip screw group of patients were given the treatment of hip replacement surgery, recording two groups of patients after cementless hip rating conditions and functional recovery, given the statistical analysis concluded. Resulst:AO cannulated screw set mostly in cement rating Class B (74.00%), while the dynamic hip screw group cemented rating mostly C-level (62.00%);two groups of patients before Harris score comparison was no significant difference (P>0.05);Harris scores two groups after treatment than before treatment conditions improved significantly (P<0.05), but there was no significant effect of improving the contrast difference (P> 0.05). Conclusion: Clinicians should be selected according to the actual situation of the patient fixation material suitable to obtain a more satisfactory clinical outcome and prognosis for the failure to implement a fixed hip arthroplasty provided favorable conditions.
