Background: To evaluate the relationship between femoral version (FV) and a angle (AA) in a large osteological collection of human femurs. Methods: The University of Iowa-Stanford osteological collection was used to evaluate the research aims. To measure FV and AA, axial photographs of the proximal femurs were taken, referenced from the posterior condylar axis. FV and AA measurements were obtained using ImageJ software, and the relationship between FV and AA was assessed with repeated-measures analysis of variance and generalized linear models. A P value of = 60 degrees). Of the 721 cadavers, 600 had both femurs available for sideto-side comparison. The average FV of femurs with cam morphology was significantly higher than that of femurs without cam morphology (11.70 degrees +/- 8.82 degrees vs. 7.99 degrees +/- 8.82 degrees, P < .001). Linear regression analysis demonstrated that increased AA was significantly correlated with increased FV (beta +/- standard error of the mean = 0.21 +/- 0.02, P < .0001). Conclusion: In a large osteological collection of human femurs, a significant positive relationship between AA and increasing FV was identified.
