Clinical observation of proximal femoral nail anti rotation intramedullary nail (PFNA) in the treatment of intertrochanteric fractures in the elderly

Abstract

Objective To observe the effect of proximal femoral nail anti rotation (PFNA) clinical curative effect in the treatment of intertrochanteric fractures in the elderly. Methods A total of 100 patients with intertrochanteric femoral fractures treated in our hospital from January 2015 to January 2017 were prospectively collected. According to the random number table method, they were divided into control group and observation group, 50 cases in each group. The observation group was treated with PFNA, and the control group was treated with PFN. The intraoperative and postoperative complications and Harris hip score and excellent rate after operation were compared between two groups. Results All patients obtained satisfactory follow-up, follow-up time was 3-6 months, with an average of (4.3±0.8) months. The incision length in observation group was (6.4±2.5) cm, the operation time was (69±10) min, the amount of bleeding was (162±46) ml, hospitalization time was (18±3) d, postoperative weight-bearing time was (14±4) d, all superior to the control group [(11.2±2.3) cm, (77±11) min, (210±80) ml, (21±5) d, (17±4) d], differences were statistically significant between two groups (P<0.05), healing time was no statistically significant difference between two groups. The recovery rate of the observation group [86.0% (43/50)] was significantly higher than the control group [68.0% (34/50)], the difference was statistically significant (χ2=32.654, P<0.05). The incidence of postoperative complications in the observation group [6.0% (3/50)] was significantly lower than the control group [18.0% (9/50)], difference was statistically significant (χ2=12.657, P<0.05). Conclusions The treatment of femoral intertrochanteric fracture in the elderly with anti-rotation nail in the proximal femur not only has the characteristics of less trauma, shorter operation time, faster postoperative recovery, but also can significantly improve the recovery of hip function and reduce complications. The incidence rate has exact clinical efficacy and high clinical safety. Key words: Hip fractures; Aged; Proximal femoral nail anti-rotation
