rotator cuff tear

The human shoulder is a remarkable complex of bones, muscles, tendons, and ligaments that provides exceptional mobility while maintaining stability. At the heart of this intricate system lies the rotator cuff, a group of four muscles and their tendons that surround the shoulder joint and play a crucial role in stabilizing the humeral head within the glenoid cavity. This article explores the comprehensive anatomy of the shoulder joint with particular focus on the rotator cuff and its components as illustrated in the anatomical diagram. Understanding this structure is essential for medical professionals, as rotator cuff injuries represent one of the most common musculoskeletal problems affecting adults, particularly those engaged in overhead activities or experiencing age-related degeneration.
