Comparison of the effect and impact on hip function of two different methods in the treatment of elderly intertrochanteric fractures

Abstract

Objective To compare the effect of anti-spin intramedullary nail and dynamic hip screw fixation in the treatment of elderly intertrochanteric fractures ,in order to investigate the clinical value of anti-spin intramedul-lary nail in elderly intertrochanteric fractures .Methods 160 elderly patients with intertrochanteric fractures were divided into the observation group and control group according to the random number table .The observation group received anti-spin intramedullary nail fixation , the control group received dynamic hip screw fixation .The fracture healing and hip function of two groups were compared .Results The operative time of the observation group was shor-ter than that of the control group ,and blood loss was less than the control group ,the differences were statistically sig-nificant（t=4.635,3.643,all P〈0.05）.The function,pain,deformity,range of motion and total scores of the obser-vation group were significantly higher than those of the control group （ t=4.433,4.364,4.865,3.876,3.645,all P〈0.05）.The postoperative hip function excellent rate of the observation group was 90.0%,which was significantly higher than 72.5%of the control group （χ^2 =5.153,P〈0.05）.Conclusion Proximal femur intramedullary nail anti-rotation fixation in the treatment of elderly intertrochanteric femoral fractures has shorter operative time ,less blood loss,and postoperative hip function recovery is good ,it is worthy of promotion .
