Treatment of femoral neck fracture in the elders by closed reduction and internal fixation using cannulated screws

Objective To evaluate the therapeutic effect of closed reduction and internal fixation using cannulated screws on femoral neck fracture in the elders.Method Thirty patients suffered from femoral neck fracture were treated by closed reduction and cannulated cancellous screws internal fixation.There were 21 males and 9 females,with mean age of 68.7 years old(range from 50 to 91 years old).Mechanisms of injury included falling(15 cases),falling from height(5 cases),and traffic accident(10 cases).According to the classification of Garden,thirteen patients belong to typeⅠ,8 patients to type Ⅱ,5 patients to type Ⅲ and 4 patients to type Ⅳ.Results The mean time of follow-up period was 2.5 years(range from 1 to 3.5 years).All patients but 2 cases were finally healed,and the average of fracture union time was 5 months.Two patients developed ischemic necrosis of femoral head in 2 years postoperatively.Accordingly,the hip joint function was excellent in 14 cases,good in 11 cases and bad in 5 cases.The healing rate was 83.3%.Conclusion Closed reduction and cannulated screws internal fixation,with simple procedure and satisfactory effect,is an effective method to treat femoral neck fractures in the elders.It can enhance fracture union and reduce incidence of avascular necrosis of femoral head.
