Background: Neck shaft angle is formed by femur shaft axis and femoral neck. This angle varies with age, physique, habits and genetic makeup vary in different ethnic group, so it is possible that the anthropometric dimensions of proximal end of femur for western group is different from Indian population.

Objectives: The objectives of this study is to determine the femur length, femur neck length and neck shaft angle of femur.

Material and Method: The present study was conducted in the Narayan Medical College, Sasaram, Bihar from November 2018 to May 2019. The specimen was collected from Narayan Medical College and other medical colleges of Bihar. Following measurement were taken, length of femur, anterior neck length and neck shaft angle of femur.

Results: The results obtained from this study were mean length of femur was 416.02±16.45 mm, right were 415±1837 mm and left were 416.02±16.45 mm. The mean neck length was 37.70±3.60, right and left were 35.15±3.64 mm and 36.27±3.50 mm respectively. The mean neck shaft angle was 133.99±4.45 degree, right and left neck shaft angle were 133.63±4.38 degree and 134.34±4.55 degree respectively.

Conclusion: There is no significant difference between measurement of right and left femur. The radiologists and orthopaedists use this normal range of measurement in diagnosis and treatment of disease of hip.
