Functional Outcome in Intertrochanteric Femur Fracture Fixation using Proximal Femur Nail

Background: This study was conducted to assess the functional outcome of Proximal Femoral Nailing in fixation of Intertrochanteric fractures of Femur. Methods: After obtaining written consent, this prospective study was conducted among 127 patients (age group>18 years) who had inter-trochanteric fracture with or without subtrochanteric extension fixed using proximal femoral nail. Mobilisation was started between first week to 6th week of fracture fixation depending on the rigidity of fixation and pain tolerance of the patient. Patients were followed up at 6th week, 3rd month and 6th month after operative fixation. Functional outcome was assessed using a physician based scoring system i.e. Harris Hip Score at every follow up. Scores were tabulated and assessment was done. Results: The present study included, 54 females (42.5%) and 73 males (57.5%) in the age group of 28 years to 94 years with the mean age of 67.7 years. Unstable inter-trochanteric fractures were seen in 106 cases (83.5%) ‘Fair’ results were seen in 17(13.4%), ‘Good’ results seen in 61(48.0%), ‘Excellent’ results were seen in 37(29.1%) patients at the end of 6 months follow up. Intraoperative complications were seen in 4 patients and late complications seen in 13 patients. Conclusion: From this study, we consider that PFN is an excellent implant for the treatment of intertrochanteric fractures. With a proper technique, PFN gives excellent clinical results with fewer failure rates and complications.
