改良张力带与形状记忆合金聚髌器治疗髌骨骨折的疗效对比

Comparative analysis of the therapeutic effect of patellar fracture between modified tension band and shape memory alloy patellar holder

【目的】对比分析改良张力带与形状记忆合金聚髌器治疗髌骨骨折疗效。【方法】回顾性分析146例髌骨骨折手术治疗患者,术后随访6个月至2年,从术后功能恢复情况、手术时间、术后平均出血量及平均住院时间进行比较分析。【结果】术后随访6个月～2年,改良张力带固定组优良率87.5%,聚髌器固定组优良率92.4%,两组比较无明显统计学差异。两组在手术时间、术后平均出血量有统计学差异（P〈0.05）。【结论】改良张力带和形状记忆合金聚髌器在疗效上无明显差异,聚髌器固定组在手术时间与术后平均出血量方面明显少于改良张力带固定组,且改良张力带固定组病例中较多患者存在钉尾刺激症,严重时影响康复锻炼,在费用允许的情况下,我们更倾向于选择形状记忆合金聚髌器固定。

【Objective】To compare the therapeutic effect of patellar fracture between modified tension band and shape memory alloy patellar holder.【Methods】146 patients with patellar fracture were followed up for six months to two years postoperatively,which were analyzed retrospectively from functional rehabilitation,operation time,the average amount of bleeding after surgery and the average hospital stays.【Result】All patients were followed up for six months to two years.The fineness rate of modified tension band group was87.5%,and the shape memory alloy patellar holder group was 92.4%.There was no statistically difference between the two groups.The two groups in operative time and the average amount of bleeding after surgery had significant difference（P〈0.05）.【Conclusion】The therapeutic effect of the two group has no statistically difference.The operation time,the average amount of bleeding after surgery of patellar holder group was significantly less than modified tension band fixation group.And many cases of modified tension band fixation group had Spiketail irritation which impact on rehabilitation exercises.Under the cost permitting,we prefer the shape memory alloy patellar fixation.
