Functional outcome after PFNA osteosynthesis in per trochanteric fractures: A longitutinal study

Abstract

Management of pertrochanteric fractures has been evolving since operative treatment started in orthopedics. The search for ideal implant is a continuous process. This study aims to assess the functional outcome of pertrochanteric fractures following osteosynthesis with PFNA. We followed up 118 cases sub classified into two groups based on Singhs Index with mean follow up of 20 months. The mean age was 68.6 years. The mean operation time was 36.5 minutes (range 24 – 70 minutes) and mean blood loss was 220 ml. 57 patients had varies co morbid conditions which needed special attention and multidisciplinary approach. The overall functional outcome according to Modified Harris Hip score was 90 patients and excellent outcome (score 90-100), 17 patients had good results (score 80- 90), 5 had fair outcome (score 70-80) and 6 had poor outcome (Score < 70).102 (87%) patients returned to prefracture state and were satisfied. We also report 2 rare complications. Overall PFNA gives good to excellent result in 90% of pertrochanteric fractures and easy to replicate even by a relatively inexperienced surgeon.
