OBJECTIVE: We aimed to compare the clinical efficacy of three different internal fixation methods, i.e. proximal femoral locking compress plate (PF-LCP), proximal femoral nail antirotation (PFNA) and dynamic hip screw (DHS) system in intertrochanteric femur fracture.

PATIENTS AND METHODS: We selected a total of 150 patients with Intertrochanteric femur fracture who were admitted to this hospital between January 2015 and December 2016 for treatment, and those patients were divided into three groups according to the difference in treatment methods, i.e., Group A (n=50), Group B (n=50) and Group C (n=50). For patients in Group A, they received the PF-LCP treatment, patients in Group B received PFNA treatment while those in Group C received DHS treatment; ultimately, clinical efficacy was compared among three groups.

RESULTS: In Group B, the efficacy was superior to those in Group A and C in terms of comparison of surgical duration, bleeding amount, time point of callus formation, healing time of fracture and length of stay (LOS) in hospital (p<0.05); after operation, the prevalence rate of complication in Group B was significantly lower than those in Group A and Group C (p<0.05); in comparison of preoperative Harris score among three groups, the different had no statistical significance (p>0.05). The Harris scores in Group B at the 1st, 3rd, and 6th month after operation were all significantly higher than those in Group A and C (p<0.05).

CONCLUSIONS: Compared with PF-LCP and DHS, PFDA can better fix the intertrochanteric femur fracture with little effect on blood circulation at the fracture end and slight damage to sclerotin, thereby accelerating the recovery of hip joint function without any increase in prevalence of complications. Therefore, PFDA has a promising clinical efficacy and safety, which is worthy of being promoted in clinical practice.
