Abstract:
Objective To evaluate the efficacy of percutaneous internal fixation with hollow screw for femoral neck fractures.Methods From June 2001 to June 2004,48 cases of femoral neck fractures,including 22 cases of fracture without displacement(type Garden I and II) and 26 cases of fracture displacement(type Garden III and IV),were treated by close reduction and percutaneous internal fixation with 3 hollow screws forming inverse triangle.Results The intraoperative blood loss was less than 10 ml,and the average operation time was 32.5 min(range,18-54 min).48 cases were followed up for 24-61 months(mean,38.2 months),union of fracture found in 97.9%(47/48) of cases,union time being 4-12 months(mean,6.2 months).According to Harris score of hip joint function,32 cases were excellent,11 cases good,3 cases fair,2 cases bad,the rate of excellent and good results being 89.6%(43/48).In 22 cases of fracture without displacement,there was no nonunion and ischemic necrosis of head of femur.In 26 cases of fracture displacement,the rate of nonunion and ischemic necrosis of head of femur were 3.8%(1/26) and 11.5%(3/26) respectively.Conclusions Percutaneous internal fixation with hollow screw has the advantages of ideal curative effects,simple procedure,reliable fixation and less complications.
