3D reconstruction of shoulder muscles in hominoid primates: Correlating scapular attachment areas with muscle volume.

ABSTRACT: Digital muscle reconstructions have gained attraction in recent years, serving as powerful tools in both educational and research contexts. These reconstructions can be derived from various 2D and 3D data sources, enabling detailed anatomical analyses. In this study, we evaluate the efficacy of surface scans in accurately reconstructing the volumes of the rotator cuff and teres major muscles across a diverse sample of hominoids. Additionally, we investigate whether muscle origin area, as a dissection-based observation, can reliably predict muscle volume. Our findings reveal that surface scans provide sufficient coverage to accurately reproduce the in situ volumes of the rotator cuff muscles. However, the volume of the teres major was estimated less reliably, suggesting that muscles with le
