微创张力带固定治疗横断型髌骨骨折

目的探讨微创张力带固定治疗横断型髌骨骨折的适应征和临床效果。方法回顾性分析1997年6月～2005年6月间应用微创张力带法治疗横断型髌骨骨折(闭合性或污染较轻的开放性骨折)38例,其中经皮穿刺克氏针钢丝张力带固定26例,经皮穿刺空心钉张力带固定12例。对骨折复位程度、关节活动度及膝关节功能进行分析。结果所有手术操作顺利。所有患者获6个月～6．5年(平均32个月)的随访。骨折愈合时间6～12周,平均7．7周；无内固定失败及创伤性关节炎等并发症发生。临床效果评定采用胥少汀式髌骨张力带固定术后评价标准,骨折复位程度：优21例,良11例,中6例,优良率为84．2%。全部病例膝关节活动度均在正常范围内,膝关节功能评价均为优良,其中优34例,良4例。结论微创张力带固定治疗横断型髌骨骨折临床效果优良。该技术主要适用于闭合性横断型髌骨骨折和创口较小且污染较轻的髌骨骨折,对于骨折块不超过3个且位置尚可的粉碎骨折也可酌情使用。

A clinical study of transverse patella fractures treated with minimally invasive tension band wire suture

Objective To discuss clinical effects and indications of minimally invasive tension band technique in treatment of transverse patella fractures.Methods Thirty-eight patients with transverse patella fracture (close or slightly polluted open ones) were treated with minimally invasive tension band technique from July 1997 to June 2005 in our department.Twenty-six were fixated with percutaneous Kirschner wire tension hand and 12 with percutaneous cannulated screw tension band.The reduction,movement range and function of the knee were analyzed.Results Surgeries went on uneventfully.All the cases were followed up from six months to 6.5 years (average,32 months).Fracture healing time lasted from 6 to 12 weeks,averaging 7.7 weeks.No such compli- cations as traumatic arthritis occurred.Reduction was excellent in 21 cases,good in 11 and fair in six,with the good-to-excellent rate being 84.2%.All the affected knee joints could move in normal range.The functional re- covery was assessed as excellent in 34 cases and good in four.Conclusions Internal fixation with minimally invasive tension band technique is good for treatment of transverse patella fractures.It is chiefly fit for close or slightly polluted open fractures with limited wound,and can also be used for the comminuted fractures if the bone fragments are no more than three and the fracture site is suitable.
