ABSTRACT
Objective To compare clinical curative effects of two types of compression hollow screws in the treatment of femoral neck fractures. Methods A retrospective analysis was carried out on clinical records of 87 cases of femoral neck fracture from February 1996 to September 2004 treated with two types of compression hollow screws,that is,doubleheaded compression hollow screws(46 cases,Group A) and AO titanium compression hollow screws(41 cases,Group B).Results A follow-up was conducted for 3 months~8 years(mean,4.2 years).No statistically significant differences were observed between the two groups.The intraoperative blood loss was significantly less and the time to bone union was significantly shorter in the Group B than in the Group A(t=5.147,P=0.000;t=5.472,P=0.000).The surgical outcomes were classified as "excellent" in 34 cases,"good" in 8,"fair" in 1,and "poor" in 3 in the Group A,while "excellent" in 37 cases,"good" in 2,"fair" in 2,and "poor" in no cases in the Group B,without statistically significant differences between the two groups in the rate of "good" or "excellent" results(89.1% vs 95.1%,?~2=0.398,P=0.528).No femoral head necrosis or non-union was found in the Group B. Conclusions Both of two types of compression hollow screws have showed advantages of simplicity of performance,minimal invasion,short operative time,reliable fixation,and high success rate,being an ideal option for femoral neck fractures.
