Morphometric analysis of proximal femur in Indian population and its implications in Total Hip Arthroplasty

Geometric understanding of the proximal end of femur is significant for functional bipedal erect posture and in pre-operative planning of osteotomy as well as the design and development of implants for THA. Moreover, the anthropological parameters of any bone are determined by genetic and environmental factors such as age, race, gender and lifestyle and this leads to racial variations in the morphological parameters of proximal end of femur owing to lifestyle, physique, applied force and their distribution in India population.The current study was designed to study and compare the morphology of proximal end of femur in Indian population and was conducted on 94 dry human cadaveric bones of unknown age and sex to determine the morphology of the proximal end of femur. We observed the Femur Length as 426.6 ± 15.82 mm, Femur Neck Length as 3.455 ± 0.378 mm and Neck Shaft Angle as 125.27 ± 2.54° amongst other parameters.The findings also revealed significant variations in the morphological parameters among different populations, emphasizing the importance of considering racial diversity in the design and selection of implants for THA for improving the success and longevity of hip arthroplasty procedures.
