闭合复位微创内固定治疗青壮年股骨颈骨折

目的 探讨青壮年股骨颈骨折的治疗方法与疗效.方法 对58例青壮年股骨颈骨折采用闭合复位空心钉内固定治疗,其中男37例,女21例；年龄19～ 56岁,平均37.5岁.Garden分型:Ⅰ型7例,Ⅱ型19例,Ⅲ型23例,Ⅳ型9例.结果 随访0.5～7.0年,平均3.8年,50例Ⅰ期愈合,平均愈合时间为5.8个月.另有3例骨不连,5例股骨头缺血坏死,其中6例Ⅱ期行缝匠肌髂骨瓣植入,3例愈合.按Harris评定:优29例,良22例,可2例,差5例,优良率为88％.结论 闭合复位、空心钉内同定是治疗青壮年股骨颈骨折有效方法,具有创伤小、并发症少、愈合率高、功能恢复满意等特点.切开复位内固定加肌骨瓣移植可作为青壮年股骨颈骨折不愈合、股骨头缺血坏死的补救治疗措施.

Closed reduction and minimally invasive internal fixation for femoral neck fractures in young adult patients

Objective To explore the treatment method for femoral neck fracture in the young adult patients and discuss the corresponding curative efficacy.Methods Closed reduction and internal fixation with hollow screws were carried out in treatment of 58 young adult patients with femoral neck fracture.There were 37 males and 21 females at age range of 19-56 years(average 37.5 years).According to Garden classification,there were seven patients with type Ⅰ fractures,19 with type Ⅱ,23 with type Ⅲ and nine with type Ⅳ.Results Follow-up lasted for 0.5-7.0 years(average 3.8 years),which showed the average one stage healing time of 5.8 months in 50 patients.Nonunion occurred in three patients and avascular necrosis of the femoral head(ANFH)in five patients,of which six patients were treated with two stage sartorius pedicled iliac graft,with fracture healing in three patients.According to Harris evaluation,the result was rated as excellent in 29 patients,good in 22,fair in two and poor in five,with excellence rate of 88％.Conclusions Closed reduction and internal fixation with hollow screw takes advantages of minor wound,few complications,high healing rate and satisfactory function recovery,and is effective in treatment of femoral neck fracture in the young adult patients.Open reduction and internal fixation with sartorius pedicled iliac graft can be used as remedial treatment for fracture nonunion and avascular necrosis.
