Background: The present study was undertaken for assessing the functional and radiological outcome of T3 proximal femur nail in the treatment of intertrochanteric fracture of femur. Materials & methods: A total of 20 patients were enrolled. Type of anaesthesia to be used was decided by the anesthesiologist. Operations were performed on a fracture table under anaesthesia. Closed reduction performed under C-arm was considered acceptable when anatomic or a slight valgus position is achieved on anteroposterior (AP) radiographic views and slight cervical anteversion was achieved on lateral radiographic views. Follow up was done and radiological and functional outcome of the patient was assessed. All the results were analyzed by SPSS software. Results: Mean Harris hip score at preoperative time, postoperative 2 months, 4 months and 6 months was 50.3, 68.6, 74.5 and 87.4 respectively. Significant results were obtained while comparing the mean Harris hip score at different postoperative follow-up time intervals. According to Harris hip score grading, excellent, good, fair and poor outcome was seen in 20 percent, 50 percent, 25 percent and 5 percent of the patients respectively. Conclusion: T3 is the new generation nail used for fixation of intertrochanteric fractures and is a dependable implant for the fixation. It has good to excellent outcomes Key words: Outcome, Intertrochanteric fracture, Femur
