改良弹性髓内钉技术治疗儿童股骨转子下骨折

Treatment of children with femoral subtrochanteric fracture with advanced elastic intramedullary nail technology

目的:探讨改良弹性髓内钉技术治疗儿童股骨转子下骨折的疗效。方法:自2009年3月至2010年12月采用改良弹性髓内钉技术治疗儿童股骨转子下骨折16例,男12例,女4例;年龄7～15岁,平均9.8岁。骨折类型:稳定型骨折(横断或短斜型)9例,非稳定型骨折(粉碎性骨折或长斜型骨折)7例。对患儿的放射学结果和并发症资料进行回顾性研究,采用Flynn评判标准对术后骨折愈合情况进行评价。结果:16例患儿术后均获得随访,时间11～32个月,平均21个月。无切口感染、骨不连及内固定物失效或断裂。骨折愈合时间8～16周,平均10.1周。骨折愈合按照Flynn评判标准进行评估,优14例,良1例,差1例。结论:使用改良弹性髓内钉技术治疗儿童转子下骨折是一种安全有效的固定方法,有利于患儿早期活动,缩短住院时间和减少并发症。

Objective：To explore curative effects of advanced elastic intramedullary nail technology in treating children with femoral subtrochanteric fracture. Methods：Form March 2009 to December 2010,16 children with femoral subtrochanteric fracture were treated with advanced elastic intramedullary nail technology. There were 12 males and 4 females ranging in age from 7 to 15 years old with a mean of 9.8 years old. According to fracture classification ,9 cases were stable fractures （traverse or short oblique type） and 7 cases were unstable fractures （comminuted or long oblique type）. Radiographs and complications were retrospectively reviewed. Fracture healing were evaluated according to Flynn criteria. Results：All children were followed up from 11 to 32 months with an average of 21 months. No incision infecton ,bone nonunion and breakage of screw occurred. The fracture healing time was from 8 to 16 weeks with an average of 10.1 weeks. According to Flynn criteria ,14 cases got excellent results,1 moderate and 1 poor. Conclusion：Advanced elastic intramedullary nail technology for the treatment of children with femoral subtrochanteric fracture is a safe and effective fixation,which is good for early mobilization,shorter the duration of hospital stays and reduce complications.
