Abstract:
Objective To investigate effects of dynamic hip screw (DHS) fixation assisted with blocking screws in treatment of intertrochanteric fracture.Methods A total of 150 patients with intertrochanteric fracture were selected as the combined treatment group,of which the patients managed by DHS intemal fixation were followed by the parallel placement of a blocking screw closely beneath the main screw for stability with its end rested on the plate.Another 87 patients managed by DHS fixation alone were determined as the control group.The surgical outcomes of the two groups were analyzed and compared.Results Good fixation without external displacement of femoral neck and cut-out of the main screw in femoral head was achieved in the combined treatment group.Also,fracture nonunion or death did not exist in the combined group.The patients in combined treatment group could take care of themselves after operation in the absence of severe pain and functional disturbance,with higher excellence rate (98.7％)than that in control group (P ＜ 0.01).Whereas,the operation failure rate was significantly lower in combined treatment group than in control group (P ＜ 0.05).Conclusion DHS fixation assisted with blocking screws is an ideal treatment of incomplete intertrochanteric fracture in medial wall of calcar femorale for it can achieve reliable fixation and definite curative effect,favor fracture healing,early functional exercise and low incidence of postoperative complications.
