Effect of cannulated compression screw treatment combined with muscular quadratus femoris-bone flap transplant in different femoral neck fractures / 中国基层医药

ABSTRACT

Objective To evaluate and compare the results of different operative methods for different types of femoral neck fracture. Methods To assess the treatment effect of two methods. Some eases of femoral neck fracture of basal-neck type and via-neck type were treated with closed reduction internal fixation with two compression spiral screws(14 eases). Other eases(32 eases) of femoral neck fracture of sub-head type and head-neck type were treated with closed reduction internal fixation with two cannulated compression screws and bone graft flaped with quadrate muscle of thigh. Results 41 cases were followed up. The average healing time was 3 years and 10 months.The bone healing rate was 97.5% ,femoral head necrosis occurred in 2.4% ,excellent and good rate was 92.6%.Conclusion Cases of femoral neck fracture of sub-head type and head-neck type were treated with closed reduction internal fixation with two cannulated compression screws and bone graft flaped with quadrate muscle of thigh. This method has the advantage of reliable fixation, simple operation, less injury and little hemorrhage. It can improve the rate of fracture union and reduce the rate of avascular necrosis of femoral head. It is the optimal method for the treatment of femoral neck fractures.
