Introduction: Morphology and statistical analysis of proximal femoral anthropometry among different populations reveals a great amount of variation. Operations on the proximal femur are one of the commonest in orthopaedic surgical practice. The aim of these operations is to restore femoral anatomy to the normal as far as possible.
Aim: The aim of present study is to remove the lacunae of information about proximal femoral geometry in Indians and evaluate its impact on implant design.
Materials and Methods: 150 normal digital antero-posterior radiographs of pelvis with both hips (PBH) of patients were studied from the department of Radiology. The Neck Shaft angle, Neck Width and Neck Length were measured.
Result: The mean neck shaft angle in Male and Female femora was 133.3
 6.83° and 129.5 ± 7.38° respectively. The mean Neck length in Male and Female femora was 30.68 ± 5.40 mm and 26.43 ± 4.82 mm respectively. The mean Neck width in Male and Female cadaveric femora was 34.04 ± 3.37 mm and 28.25 ± 2.82mm respectively. The mean Neck length in both Male and Female femora on both Right and Left sides showed significant positive correlation with the Neck width.
Conclusion: This study will help the biomechanical engineers in altering the implant designs to suit the needs of Indian Population.

Keywords: Neck length, Neck shaft angle, Neck width, Proximal femoral geometry.
