📌 Rotator Cuff Muscles: Anatomical & Biomechanical Perspective

This image illustrates the rotator cuff muscle group, a crucial anatomical and biomechanical unit that stabilizes the shoulder joint while allowing controlled mobility. Anatomically, these muscles originate from the scapula and insert onto the head of the humerus, forming a musculotendinous “cuff” around the glenohumeral joint.

From an anatomical point of view, the rotator cuff consists of four muscles: supraspinatus, infraspinatus, teres minor, and subscapularis (SITS).
• The supraspinatus lies superiorly and initiates the first phase of shoulder abduction.
• The infraspinatus and teres minor are positioned posteriorly and are primary external rotators of the shoulder.
• The subscapularis, located on the anterior surface of the scapula, is the main internal rotator of the shoulder.
Together, these muscles provide dynamic stability by keeping the humeral head centered within the shallow glenoid fossa.

From a biomechanical perspective, the rotator cuff functions less as a prime mover and more as a joint stabilizer. During arm elevation, the deltoid produces an upward shear force on the humerus. The rotator cuff counters this by generating a compressive and downward force, preventing superior migration of the humeral head and maintaining optimal joint congruency.

Each muscle contributes to a balanced force-couple mechanism. The subscapularis anteriorly and the infraspinatus–teres minor posteriorly work together to control humeral rotation, while the supraspinatus assists in abduction and joint compression. This coordinated activity allows smooth, pain-free shoulder motion during daily activities and overhead tasks.

Clinically and functionally, dysfunction of any rotator cuff muscle disrupts shoulder biomechanics, leading to impingement, instability, reduced strength, and altered movement patterns. Weakness or delayed activation increases stress on passive structures and predisposes the shoulder to injury, especially in athletes and overhead workers.
