ABSTRACT
Objective To compare the clinical efficacy of proximal femoral nail anti-rotation ( PFNA ) fixation and hemiarthroplasty in the treatment of elderly unstable intertrochanteric fractures .Methods 72 cases with unstable intertrochanteric fractures were divided into the two groups by random number table ,each group had 36 ca-ses,the control group was given implementation of hemiarthroplasty while the observation group was given PFNA fixa -tion,the clinical therapeutic effect were compared between the two groups .Results It showed no significant differ-ence in operative time between the two groups (t =2.58,P>0.05);the blood loss of the observation group was (187.52 ±10.83)mL,which was significantly less than that of the control group (t=9.56,P0.05). Conclusion PFNA fixation and hemiarthroplasty for treatment in elderly unstable intertrochanteric fractures have good effect ,and the patients should be based on the specific clinical circumstances , under strict control of surgical contraindications choose the right surgery .
