Comparision of the effects of different fixation methods in the treatment of elderly patients with intertrochanteric fracture

Objective To compare the clinical efficacy of different internal fixation methods in the treatment of intertrochanteric fractures.Methods he clinical data of 270 elderly patients with intertrochanteric fracture were retrospectively analyzed.According to the different internal fixation methods,the patients were divided into three groups,namely anti-rotation intramedullary nail(PFNA) group,dynamic hip screw(DHS) group and anatomic locking plate (LCP) group,90 cases in each group.The incision length,operative time,blood loss,hospital stay,postoperative weight-bearing time,postoperative bleeding and postoperative complications were compared among the three groups.The fracture healing was compared among the three groups during follow-up.Results The incision length of PFNA group compared with the DHS group (t =11.248,P =0.000) and the LCP group (t =12.371,P =0.000),the differences were significant.The operative time of PFNA group compared with the DHS group (t =15.048,P =0.000) and the LCP group(t =12.822,P =0.000),the differences were significant.The blood loss of PFNA group compared with the DHS group (t =5.803,P =0.000) and the LCP group (t =10.879,P =0.000),the differences were significant.The incidence rates of complications in PFNA group,DHS group,LCP group were 3.33％ (3/90),10.00％ (9/90),13.33％ (12/90),respectively,and theincidence rate of PFNA group was lower than the other two groups (x2 =5.268,P =0.026).The average period of fracture healing in PFNA group compared with the DHS group (t =10.217,P =0.000) and the LCP group (t =4.530,P =0.000),the differences were significant.Conclusion PFNA in the treatment of senile intertrochanteric fractures has advantages such as less trauma,shorter operation time,less blood loss,fewer complications,faster recovery,it is worthy of clinical use.
