Understanding Shoulder Anatomy and Function

Shoulder health primarily revolves around the stability of the glenohumeral joint, which is the ball-and-socket joint commonly referred to as the shoulder joint. However, the shoulder girdle is composed of four articulations, including the acromioclavicular, sternoclavicular, and scapulothoracic joints, all of which play crucial roles in function and injury prevention. A significant number of injuries seen in baseball players often stem from issues at the glenohumeral joint, underscoring the need for a comprehensive understanding of all associated joints. Focusing on the movement patterns and stability of these proximal joints can lead to improved outcomes and reduce the likelihood of injury at the glenohumeral joint.
