微创股骨近端髓内钉治疗股骨转子间骨折的临床效果观察

目的探讨微创股骨近端髓内钉（proximal femoral nail antirotation,PFNA）在治疗股骨转子间骨折中的临床应用价值。方法 2009年1月至2011年2月对18例股骨转子间骨折行微创复位PFNA内固定术。结果 18例患者均获随访,随访时间8～24月,平均13月。骨折均愈合,髋关节功能Harris评分优15例、良2例、可1例,平均得分为90.2分;无感染、螺钉松动、断裂,无螺旋刀片切割、退出,无髋内翻、股骨头坏死。结论微创PFNA治疗股骨转子间骨折具有临床效果好、创伤小、固定可靠、并发症少等优点。

Observation on the clinical effect of proximal femoral nail for intertrochanteric fracture

Objective To explore the experience of operation with proximal femoral nail(PFN) in minimal invasive treatment of intertrochanteric femur fracture. Methods Eighteen cases of intertrochanteric fracture were operated by minimally invasive PFN from Jan 2009 to Feb 2011.Results Follow-up visit was carried out in all the patients.The mean follow-up period was 13 months(8~24 months).Bone healing was obtained in all patients.Hip function was assessed by Harris Hip Score.Fifteen cases were assessed as excellent,2 cases as good,and 1 case as fair.The average score was 90.2.And there were no complications such as infection,looseness or breakage of screw,incision or exit of spiral blades,coxa vara and avascular necrosis of femoral head. Conclusions Minimally invasive PFN can be used to treat intertrochanteric fracture for its good clinical outcomes,minimal invasion,fastness and low incidence of complications.
