Comparative Analysis of Three Internal Fixation Methods for Intertrochanteric Fracture of Femur in the Elder

As the average life span of the Chinese prolongs, the number of intertrochanteric fractures of the femur in elderly patients has increased all the time, and gradually becomes a more common type of fracture in elderly patients. From January 2011 to December 2016, 137 elderly patients with intertrochanteric fractures were treated with 3 mehhods, including locking plate, proximal femoral nail (PFNA) and artificial femoral head replacement. The mean age was 79.16±3.45 years. The mean follow-up time was 17.20±1.30 months. The operative time, intraoperative bleeding volume, postoperative complications, and Harris score of the hip joint at 1 month and 1 year after surgery were compared among the three groups. Statistical analysis by SPSS 22.0 software showed that the operation time of group C was the shortest, followed by group B and group A. The difference was statistically significant (p 0.05); There was no significant difference in bleeding volume between the three groups (p>0.05). Group A had the lowest complication rate, followed by group C and group B. But there was no significant difference between the three groups (X2=0.0618, p>0.05). All the patients were cured and discharged after active symptomatic treatment. Among the patients, the mean Harris score of group A was 38.52±6.51 at 1-month follow up postoperatively; the mean Harris score of group B was 44.28±5.97 at 1-month follow up postoperatively; the mean Harris score of group C was 70.59±6.99 at 1-month follow up postoperatively, the C group was the best and the B group was the second. There was a significant difference between the three groups (p 0.05). During the follow-up period, there was no loosening or breakage in the internal fixation, and the fracture healed well. This study concluded that locking plate, PFNA or artificial femoral head replacement can achieve satisfactory clinical results in elderly patients with intertrochanteric fractures, but artificial femoral head replacement can achieve early functional recovery, more conducive to elderly patients.
