Introduction: Intertrochanteric femoral fractures constitute approximately 50% of all hip fractures. Reliable fixation of intertrochanteric hip fractures, particularly those /with unstable patterns and cortical comminution, remains an unsolved problem. Recently popular modality is fourth generation of intramedullary nails like the Proximal Femoral Nails. But these are not found to be very suitable in Indian population because of variation in anthropometry of proximal femur. This may lead to an increased difficulty in placement of femoral neck screws. Therefore, Trochanteric Fixation Nail (TFN) which is smaller in size than Proximal Femoral Nail (PFN) was introduced.
Aim of the Study- To assess the clinical & radiological outcome of Unstable Intertrochanteric fractures treated with TFN.
Materials & Methods- A prospective study done at the Department of Orthopaedics, Rajah Muthiah Medical College & Hospital, Annamalai University, Chidambaram. Patient with Intertrochanteric fractures were treated with TFN (short intramedullary nail) &Follow up done at regular intervals for a period of 18 months.
Results &Conclusion-- Thirty patients with unstable Intertrochanteric fracture were treated with TFN from June 2014 to August 2016. Mean age of the patients 65.07 years (35-92 years). Overall mean time of radiological fracture union was 15 weeks (range 13-18). Mean hospital stay was 13 days (range 12 to 18 days).The mean Modified Harris Hip Score of the TFN was 88.25.In our study, Patients with Unstable intertrochanteric fracture treated with trochanteric fixation nail had results that were comparable with that of other studies done elsewhere with good radiological and functional outcome.
