Closed reduction and minimally invasive internal fixation for femoral neck fractures in young adult patients / 中华创伤杂志

ABSTRACT

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.
