Sphere-on-Sphere model: shoulder model including humeral head translation
This webinar will present a musculoskeletal shoulder model that uses a sphere-on-sphere representation of the glenohumeral joint together with force-dependent kinematics (FDK) to enable realistic translation of the humeral head, rather than using a ball-and-socket representation of the joint. This results in more physiologically plausible kinematics of the humeral head and more realistic muscle activation patterns, especially for the cuff muscles. The model improves the ability to investigate glenohumeral stability, including the impact of variations in joint congruence or rotator cuff tear configurations on muscle compensation and joint loading.
