Critical Shoulder Angle: Radiological Study and Musculoskeletal Model

This lecture presents a radiological study investigating the critical shoulder angle and its association with rotator cuff tears and osteoarthritis. It also explores a musculoskeletal model analyzing the activation and force distribution of shoulder muscles. The critical shoulder angle is discussed as a potential indicator for tendon tears and cartilage degeneration, with specific parameters such as acromion index and glenoid inclination being examined. Additionally, the rocking horse effect in shoulder joint replacement and biomechanical aspects of glenoid components are covered, including edge displacements and bone substitutes. The lecture concludes with a discussion on stress distribution and debonding in glenoid components under different loading conditions.
