The Effects Of Proximal Femoral Nail Anti-Rotation(PFNA) For Treatment Of Femoral Intertrochanteric Fracture

Objective:Retrospective analysis of proximal femoral nail anti-rotation(PFNA) treatment of femoral intertrochanteric fractures, evaluation PFNA intertrochanteric fracture treatment of the clinical efficacy for future research deeper to provide a basis and to promote a systematic summary of the internal fixation of clinical experience.Methods:In this study, theoretical research on the part of the system of modern medicine of intertrochanteric fracture of the relevant anatomy,incidence, etiology and pathogenesis, diagnosis, biomechanics and treatment methods.Retrospective analysis40cases from January2012to December2012, using the proximal femoral nail to treat the intertrochanteric femur fracture. Included males18cases, females22cases. The average age was76.1years (range:37-93).According Evans classification standard, II:12cases, III:25cases, IV:leases, V:2case. Observation of the patients operative time, bleeding situation, postoperative complications, hopitalization days, follow up of patients with fracture healing time, the use of Harris hip score criteria to assess risk of hip function, assessment of therapeutic effect PFNA.Result:No incision infection occured in the cases. all the40patients healed at degree1. And no internal fixation loosening and fracture displacement was found in the following investigation. And the good rate of six-month-postoperative functional evaluation was85%.Conclusion:In this study, all types of intertroehanterie fracture can be applied by PFNA. Its advantage small incision, less trauma, simple mani-pulation, fast recovery and easy removal in the treatment of intertrochanteric femur fracture, which provides reliable effect, it is worth for clinical use.
