Abstract
BACKGROUND: Standard commercially available implants and prosthesis may not be the best fit for Indian population due to large anatomic variation. Orthopedic surgeons always stress the need for proper sized implants. But at present the commercially available implants are designed for western population. Due to this mismatch, complications like aseptic loosening, screw pullout, discomfort, pain, non-union, malunion, avascular necrosis, improper load distribution and ultimately implant failure may arise. PATIENTS AND METHODS: The study was conducted in 200 individuals with normal hip joint of south Indian region attending Coimbatore medical college hospital. CT scanning of proximal femur was done and parameters measured. Patient name, age, sex, height and weight measured once the CT scan report of bony structure turn out to be normal. To assess the existing relationship between head and neck with femoral shaft by neck shaft angle, neck width, head diameter, acetabular angle of Sharp, horizontal offset, vertical offset, medullary canal diameter at the level of lesser trochanter and acetabular version parameters measured. These parameters tabulated and compared with western population and sexual and right and left side differences statistically analyzed. RESULTS: Our measurements showed a large difference on comparing with western population due to constitutional, racial and behavioral differences. High neck shaft angle measured in males comparing the females. Subtle yet significant differences noted in other parameters between sexes. Even differences noted in between sides. CONCLUSION: This study indicates a need for redesign of fracture implants and replacement prosthesis at hip. The obtained anthropometric femoral dimensions can be used to design and develop indigenous hip joint implants in India. The results of this study can also be used in forensic anthropometric studies.
