| Objective To compare the curative effect of the PFNA and locking DHS in treatment of intertrochanteric fracture of femur (IFF). Methods Retrospective analysis the clinical data of 79 cases of elderly osteoporotic patients with femoral intertrochanteric fractures from January 2014 to June 2016, and divided the 79 cases into two groups according to internal fixation methods which is the locking DHS and the PFNA group. Afterwards, comparisons were made of traction reset time after anesthesia, operative time, the blood loss, volume of drainage after surgery, intraoperative and postoperative complication and last Harris hip function score were recorded. Results Compared with locking DHS group, PFNA group had advantages in operation time, intraoperative blood loss, postoperative volume of drainage and hospitalization time. All 79 patients were followed up with an average of 8.9 months (range, 6 to 18 months). The average time of fracture healing is 4.5 months in PFNA group, and 5.7 months in locking DHS group. The excellent rate of PFNA group was 95.2% for last Harris hip function scores, and 94.6% in locking DHS group (P＜0.05). Conclusion PFNA internal fixation for femoral intertrochanteric fracture had good clinical efficacy. Compared with locking DHS, the biomechanical performance of PFNA was better, it is minimally invasive, good support, simplicity of operator for elderly osteoporotic patients, and it is safe. But there was no difference in hip function between the two groups. |
