Femoral anteversion has recently gained popularity in research in light of its practical applications in hip replacement surgery. Previously, surgeons would estimate the placement of a prosthetic femoral neck by standards based on homogenous populations of Caucasian males. This research project seeks to correct this bias by exploring the variation in femoral anteversion by sex, ethnicity, body mass index, and age. Furthermore, this study tested for a correlation between angle of anteversion and occurrence of osteoarthritis in individuals over the age of forty. Three hundred sixty pairs of femurs from the Hamman-Todd collection at the Cleveland Museum of Natural History were individually measured using the National Institute of Health program, ImageJ64. Using Stata, I then analyzed my angle measurements to determine if any of my factors correlated with a significant variation in femoral anteversion. My analysis showed significance for sex (male > female), and age (angles decreasing with age). The decrease of angles with age was consistent with projections in previous studies showing a decrease in angles from birth until the mid-twenties. However, most existing literature shows significant for females > males instead of the opposite. The unexpected correlation between females and smaller angles of anteversion illustrates the complex nature of anteversion variation and the need for further, more specific research.
