髌韧带减张钢丝在髌骨下极骨折治疗中的效果分析

Analysis of efficacy of patellar ligament tension band wiring in fracture of the lower patellar pole

目的探讨髌韧带减张钢丝在髌骨下极骨折治疗中的临床效果。方法选取2013年1月至2018年10月21例髌骨下极骨折患者,分为治疗组12例和对照组9例,比较两组患者的内固定失效率及末次随访时Bostman髌骨骨折功能评分的差异。结果 21例患者均获得随访,两组患者Bostman髌骨骨折功能评分比较,差异有统计学意义(P<0.05);两组患者术后内固定失效率比较,差异有统计学意义(P<0.05),对照组内固定失效率显著高于治疗组。结论髌骨下极骨折行内固定同时辅助使用髌韧带减张钢丝疗效优于单纯内固定治疗。

Objective To investigate the efficacy of patellar ligament tension band wiring on fracture of the lower patellar pole.Methods Twenty-one patients with lower patellar polar fractures from January 2013 to October 2018 were divided into 12 cases in the treatment group and 9 cases in the control group.The differences in failure rate of internal fixation and Bostman score during the final follow-up were compared between both groups of patients.Results All of the 21 patients were followed up,and there was significant difference in Bostman score between the two groups(P<0.05).There was significant difference in postoperative failure rate of internal fixation(P<0.05),and the control group showed a higher failure rate of internal fixation than the treatment group.Conclusions In treating fracture of the lower patellar pole,the efficacy of internal fixation plus patellar ligament tension band wiring is superior to that of internal fixation alone.
