Introduction: Trochanteric fractures constitute one of the commonest fractures encountered in the elderly. Operative management which allows early rehabilitation and offers the patient the best chances for functional recovery is the treatment of choice for virtually all trochanteric fractures. Objective: To compare the clinical, functional and radiological outcome of unstable intertrochanteric fractures femur treated randomly with proximal femur nail(PFN) and Dynamic hip screw(DHS). Functional and clinical outcome measurement using harris hip score. Methods: This prospective randomized study compared the outcome of elderly patients with pertrochanteric fracture and carried out in Nizam`s institute of medical sciences Hyderabad in the year 2018 and 2019. 60 patients with unstable intertrochanteric fractures were included. 30 patients were operated on by the Proximal Femoral Nail (PFN) and 30 patients were operated on by Dynamic hip screw (DHS). Functional outcome was assessed by Modified Harris Hip Score. Results: The rate of union was similar in both groups. The mean Harris hip Score in the DHS group was 82.1 compared to 83.5 in PFN. Effective results were seen in 63.3% of cases in the DHS group and 73.3% cases in the PFN group. The mean surgery time for DHS (76 min) was marginally higher than that for PFN (76 min) which is non-significant (P=0.281). The blood loss was also marginally lower in the IM Nail group (264ml) compared to the DHS group (354 ml) which was also not statistically significant (P=0.14). Conclusion: The implant-related complications were much lesser in the patients treated with Dynamic Hip Screw(DHS). We did not encounter any secondary femoral fracture in patients managed by proximal femoral nails though this is one of the common complications reported in other studies.
