Abstract

Background: Orthopedic femoral implants are predominantly designed based on Western anthropometric data, which may not accurately reflect the skeletal dimensions of the Indian population. Using ill-fitting implants can lead to periprosthetic fractures, accelerated joint wear, and altered mechanics.

Objective: To perform a detailed osteometric evaluation of the proximal femoral segments in an adult Indian population to provide a reliable database for indigenous implant design.

Material and Methods: An osteometric analysis was conducted on 158 dry, ossified adult human femora. Six parameters were measured using digital calipers and goniometers: Vertical and Transverse Head Diameters (VDH/TDH), Neck-Shaft Angle (NSA), Femoral Neck Length (FNL), Anteroposterior and Vertical Neck Width, and Bi-trochanteric Width.

Results: The mean VDH (45.95 ± 1.59 mm) consistently exceeded the TDH (44.07 ± 1.26 mm), indicating an elliptical head profile. The mean NSA was 128.97o ± 2.60o, showing a significant varus trend compared to Western standards. The Vertical Neck Width averaged 29.40 ± 2.66 mm, though 22.78% of specimens had a width of less than 27 mm, creating a restricted "safety corridor" for internal fixation. Correlation analysis showed no significant relationship between head diameter and neck width (r = -0.027), indicating that these dimensions vary independently.

Conclusion: The Indian proximal femur possesses unique geometric characteristics, including smaller overall dimensions, elliptical head morphology, and a varus-aligned neck. The independence of anatomical variables challenges the logic of "proportional scaling" in manufacturing. These findings advocate for the development of indigenous, modular implants to ensure anatomical congruence and reduce surgical complications in the Indian demographic.
