Methodological approach of this study. (A) Specimen selection for CT-scanning, image courtesy of R. Butler. (B) Composite pelvis and hindlimb based on SAM PK 5867 (white), SAM PK 5867 mirrored from opposite side (orange), SAM PK 6047A (blue), SAM PK K8309 (purple) and UMZC T.692 (red). (C) Geometric primitive shapes fitted to the acetabulum and femoral head to determine the joint centres. (D) Simulation setup in Maya in the reference pose. ACS anatomical coordinate system, JCS joint coordinate system. A detailed description of the reference pose, with the ACS and JCS setup is in the Supplementary Information.
