Introduction: One of the most common fractures in the elderly is inter-trochanteric fractures where surgical management allows better functional and rehabilitation outcomes making it a treatment of choice. Aim: To compare radiological, functional, and clinical outcomes following treatment of unstable intertrochanteric femur fractures using dynamic hip screw (DHS) or proximal femur nail (PFN). Methods: The study assessed 120 subjects with unstable intertrochanteric femur fractures where 60 were treated with DHS and the other 60 with PFN. For assessment of the outcomes, Harris hip scores were used. Results: Most surgeries were done in 56-70 minutes in 30% (n=18) subjects and 37% (n=22) subjects in DHS and PFN group respectively which was statistically non-significant with p=0.86. Most common complication was lateral cortex shattering in 16.6% (n=10) study subjects followed by ill-fitting jig in 13.3% (n=8) study subjects and distal locking difficulty in 10% (n=6) study subjects respectively. Mean Harris hip score was higher in PFN group (83.5±2.38) compared to DHS group (82.1±2.32).
