儿童股骨颈骨折不愈合的研究进展

Research advances of femoral neck fracture nonunion in children

近年来随着交通事故伤及高空跌落伤等高能量创伤越来越常见,儿童股骨颈骨折的发病率也逐年增加。手术复位及内固定是治疗移位型儿童股骨颈骨折的主流方法,但与其他儿童骨骼损伤相比,股骨颈骨折的并发症发生率高、预后较差。股骨颈不愈合(femoral neck nonunion,FNN)是股骨颈骨折的常见并发症之一,但FNN的处理目前仍是临床一大难题。本文对导致儿童FNN的各种风险因素进行归纳分析,并对目前的治疗进展进行综述,为FNN的预防和处理提供参考。

Recently pediatric femoral neck fractures have occurred frequently due to such high-energy traumas as traffic accidents and falls from heights.Surgical reduction and internal fixation are routinely performed for displaced pediatric femoral neck fractures.As compared to other pediatric skeletal injuries,femoral neck fractures carry a high incidence of complications and unfavorable outcomes.Femoral neck nonunion(FNN)is a common complication of femoral neck fractures in children.However,its proper treatment has remained a major clinical challenge.This review summarized various risk factors leading to FNN and offered an overview of recent researches to guide the prevention and management of FNN in children.
