Background: The morphology of the proximal femur is a topic of extensive research. The hip joint is one of the most commonly replaced joint. The era of replacement has given rise to various implants that can be used to replace the proximal femur. This present study addresses these issues involving ethnic differences in the geometry of the proximal femur in Indians and its differences between people of various ethnicity.
Methods: The total population that was radiographed was 178 (n=178). There were 78 males and 100 females. The age of the participants were spaced from 25-75 years age groups. The parameters were measured.
Results: The canal flare index in South-Indians was an average of 3.23 with 70% of the study population having normal CFI (3-4.5), 30% of the population having a stove pipe configuration CFI (<3). Majority of the Indian population favour a un-cemented fixation (70%).
Conclusions: In summary all current implants have to be revised on population basis to fit the changing anthropometry of our proximal femur.
