Dynamic hip screw and proximal femoral nail anti-rotation,in the treatment of femoral intertrochanteric fracture of 90 cases

Abstract

Objective To compare the treatment effects of senile intertrochanteric fracture with the dynamic hip screw(DHS),proximal femur locking compression plate (LCP),anti-spin femur proximal femoral nail(PFNA).Methods Ninety cases of femoral rotor fracture patients were treat in our hospital from September 2010 to March 2012 by DHS(n =30),LCP(n =30) and PFNA(n =30) treatment of femoral intertrochanteric fractures.We compared the surgical time,blood loss,fracture healing time,postoperative complications and hip function scores.Results In DHS,LCP and PFNA group,the blood loss ((287.1 ± 72.0) ml,(214.9 ± 65.8)ml,(85.0 ± 33.6) ml,F =88.7,P ＜ 0.05),the operative time ((1.51 ± 0.07) h,(1.49 ± 0.04) h,(0.70 ±0.10) h,F =445.8,P ＜ 0.05),and both were significant difference.But the fracture healing time ((15.2 ±1.7) weeks,(17.0 ± 1.4) weeks,(15.9 ± 1.8) weeks,F =1.4,P ＞ 0.05),there was no significant difference.The PFNA group had a good hip Sander' score of 96.7％,better than other two groups (87.5％、96.8％) (x2 =39.06,P ＜0.05).The weight-beating time of PFNA group is earlier than the other two groups ((1.00±0.36) cm,(0.80±0.12) cm,(0.60±0.19) cm,F=30.4,P＜0.05).Conclusion PFNAinthe treatment of femoral intertrochanteric fracture has advantages in minimally invasive,less blood loss,and help patients go through the perioperative period.
