Introduction: Proximal Femoral Geometry is subjected to a wide range of ethnic variations. Various research article indicates that the geometry of the proximal femur in the Indian population considerably differ from the European and American standard. Proximal femur morphometry parameters are vital to design and develop arthroplasty components. Currently, arthroplasty components widely used are based on western standards. Improper size of hip joint arthroplasty may result in joint congruence, micromotion, osteoarthritis and tendinopathy. The present study comprehensively analyzes the proximal femur anthropometry in the South Indian population and comparison with other ethnic groups. Aims: To determine the proximal femur geometry using radiographs and to analyze the proximal femoral geometrical variation between the south Indian population and various ethnics. Materials and Methods: A study was conducted in 388 non - pathological hip joint X-rays collected from the Southern Indian population. The primary objective of the study is to measure proximal femoral geometry and compare the difference with various ethnic groups. Measurements like femoral head diameter, Neck width, Neck shaft angle, Femoral offset and Medullary canal diameter are calculated using Picture Archiving Communication System (PACS). Result: In the present study, the proximal femur anthropometry of the South Indian population differs from the Western population. In some parameters, the present study also differs from the North Indian population Neck shaft angle in the present study is smaller than the western as well as in the South African population. Conclusion: The present study of the proximal femur in the south Indian population considerably differs from the dimensions of the Western ethnic population. The study may aid in the development of proximal femoral arthroplasty components suitable for the Indian population.
