Common Causes Of Rotator Cuff Injuries
A rotator cuff injury involves damage to the muscles and tendons that surround the shoulder joint, which can affect shoulder movement and stability. The rotator cuff consists of four muscles and their associated tendons: the supraspinatus, infraspinatus, teres minor, and subscapularis. These muscles and tendons work together to stabilize the shoulder and allow for a wide range of arm movements.
1. Tendonitis: Inflammation of the tendons, often due to overuse or repetitive strain.
2. Bursitis: Inflammation of the bursa (a fluid-filled sac that reduces friction) in the shoulder.
3. Tears: Can be partial or complete, where the tendon is frayed or completely severed. Tears can occur due to acute injury or degenerative changes over time.
- -Acute Injury: Sudden trauma, such as falling on an outstretched arm or lifting something too heavy.
- -Repetitive Motion: Activities that require repetitive shoulder movements, such as painting, swimming, or thowing.
- - Degenerative Changes: Age-related wear and tear, leading to tendon degeneration and increased susceptibility to injury.
- -Poor Posture: Chronic poor posture can strain the rotator cuff muscles and tendons.
-Shoulder Pain: Especially when lifting the arm, reaching overhead, or sleeping on the affected side.
-Weakness: Difficulty lifting or rotating the arm.
-Limited Range of Motion: Stiffness and reduced ability to move the shoulder.
-Crackling Sensation: A popping or crackling sensation when moving the shoulder.
