ABSTRACT
Objective To compare the clinical effects of proximal femoral nail antirotation (PFNA) and dynamic hip screw (DHS) in the treatment of intertrochanteric fractures in elderly patients.And provide a reasonable basis for clinical treatment of elderly patients with intertrochanteric fractures.Methods The clinical and follow-up records of 58 elderly patients with intertrochanteric fractures treated by PFNA and DHS were retrospectively reviewed.For times of operation,blood loss in operation,length of incision,incidents of complication and Harris's hip functional standard score were compared and analyzed.Results PFNA group operation time[(59.61 ± 8.27)min],amount of bleeding[(234.51 ± 38.80)ml] were both better than the DHS group of[(83.54 ± 11.12)min and (446.57 ±54.01) ml] respectively.There were significant differences (t =9.80,18.10,all P ＜ 0.05).The satisfactory rate was 92.8％ in PFNA group,higher than the DHS group's 83.3 ％ (x2 =6.18,P ＜ 0.05).There was significant difference between two groups in the incident of complication,DHS group was higher.Conclusion PFNA internal fixation with a minimally invasive,fixed solid and recovery fast,is the better internal fixation in the treatment of elderly intertrochanteric fracture patients.
