Background: Intramedullary devices are the most popular mode of management for unstable intertrochanteric femur fractures. These implants have been designed based on geometric studies of proximal femur of western population which varies from other ethnic groups. Objective: This study is aimed to measure proximal femur parameters in south Indian population using computed tomography (CT). Methodology: A descriptive anatomical study, conducted by measuring proximal femoral parameters using computed tomography scans which were available in the Department of Radio-diagnosis, S. Nijalingappa Medical College and Hospital and Research Centre, Bagalkot. Parameters assessed are-Neck Width(NW), Canal width at Lesser trochanter anteroposterior (CW-LT AP), Canal width at lesser trochanter mediolateral (CW-LT ML), Neck Shaft Angle (NSA), Head Size (HS), Horizontal Offset (HO), Vertical Offset (VO), Greater trochanter to lesser trochanter distance (GT-LT) and Trochanteric region width (TRW)
