A New Method for Whole Bone Analysis of Bilateral Asymmetry.

ABSTRACT: Postcranial asymmetry of bones has been mostly studied with linear or angular measurements. Although conclusive, these measurements fail to capture the differences of the entire bone surface. Here, we develop a methodology to measure whole bone bilateral asymmetry from 3D models. We demonstrate the method using the humerus and the second metacarpal. We compare right and left bones of the same individual (bilateral variation) to that of different scans of the same bone (interscan variation) and of the same bone from different individuals (interindividual variation) to show that the method functions and is able to segregate different degrees of variation. The interscan variation is the lowest, while the interindividual variation is the greatest, and the bilateral variation falls between the
