Comparative study of PFNA and DHS in improving hip joint function of elderly patients with femoral intertrochanteric fracture / 中国现代医生

ABSTRACT

Objective To compare the effects and safety of proximal femoral nail anti-rotaion (PFNA) and dynamic hip screw (DHS) in improving the hip joint function of elderly patients with femoral intertrochanteric fracture. Methods Ninety-six elderly patients aged over sixty years old with femoral intertrochanteric fracture treated in Department of Or-thopedics from August 2011 to August 2014 were divided into groups according to the hospital admission order. The PFNA group, consisting of 48 patients, was given PFNA treatment, and the DHS group, consisting of 48 patients, was given DHS treatment. The operative time, total intraoperative bleeding amount, hip joint function recovery, fracture healing time and occurrence of operative complications were observed. Results The intraoperative bleeding amount, operative time and fracture healing time of the PFNA group were significantly less than those of the DHS group ( P<0 . 05 ) . The excellent and good rate of hip joint function of the PFNA group was 52.08%, which was significantly higher than the 29.17% of the DHS group (Z=-2.597, P<0.05). The occurrence of postoperative complications of the PFNA group was significantly less than that of the DHS group (P<0.05). Conclusion Compared to DHS, PFNA conforms to the mini-mally invasive principle and the biological and mechanical requirements of modern medicine and its nail anti-rotation system can reduce intraoperative bleeding amount, shorten operative time, promote porosis and early fracture healing, improve hip joint function and reduce the occurrence of postoperative complications, which is quite suitable for elderly patients with femoral intertrochanteric fracture.
