螺旋型髋臼与压配型髋臼治疗老年股骨颈骨折的早期疗效对比

Comparison of early effects of spiral-type acetabulum and press-fit acetabulum prosthesis in the treatment of elderly patients with femoral neck fracture

目的比较螺旋型髋臼与压配型髋臼治疗老年股骨颈骨折患者的早期疗效。方法对30例老年股骨颈骨折患者行全髋关节置换术(THA),根据采用髋臼假体不同将患者分为螺旋型髋臼组(15例)和压配型髋臼组(15例)。采用Harris评分进行疗效评价,并进行影像学评价和术后并发症比较。结果 30例患者均获得随访,时间8~28个月。末次随访时,螺旋型髋臼组在髋关节功能改善情况上高于压配型髋臼组(P<0.05),但两组优良率相似(P>0.05);两组影像学评价及并发症发生率差异均无统计学意义(P>0.05)。结论螺旋型髋臼治疗老年股骨颈骨折可获得较好的初始稳定性,可早期下地进行功能锻炼,疗效满意。

Objective To compare the early effects of spiral-type and press-fit acetabulum prosthesis in the treatment of elderly patients with femoral neck fractures.Methods The 30 elderly patients with femoral neck fracture underwent total hip arthroplasty（THA）,these patients were divided into spiral-type acetabulum prosthesis group （15 cases） and press-fit acetabulum prosthesis group（15 cases）.The therapeutic effect was evaluated by Harris score,radiological results,and compared complications.Results The 30 patients were followed up for 8~28 months.Spiral-type acetabulum prosthesis were better than press-fit acetabulum prosthesis in hip joint function improvement （P〈0.05）,but they had the similar excellent-good rate（P〉0.05）.There was no statistical significance in radiological evaluation and complication incidence rate with two groups（P〉0.05）.Conclusions The elderly patients with femoral neck fracture treated by spiral-type acetabulum prosthesis have preferable stability,early functional training can be done,prevent complication,and have satisfactory effects.
