Rotator cuff injuries refer to damage or tears in the group of muscles and tendons that surround the shoulder joint, known as the rotator cuff. The rotator cuff consists of four muscles: the supraspinatus, infraspinatus, teres minor, and subscapularis. These muscles work together to stabilize and allow movement of the shoulder joint.

Rotator cuff injuries can occur due to various reasons, including acute trauma, repetitive overuse, or degenerative changes in the tendons. Common types of rotator cuff injuries include:

Rotator cuff tendonitis: This refers to inflammation or irritation of the rotator cuff tendons, often caused by repetitive overhead motions or excessive stress on the shoulder. It can result in pain, weakness, and limited range of motion.
Rotator cuff tears: A tear can occur in one or more of the rotator cuff tendons, either as a partial tear or a complete tear. Tears can be acute, resulting from a sudden injury, or degenerative, developing gradually over time. Symptoms may include pain, weakness, difficulty lifting or moving the arm, and a clicking or popping sensation.
Rotator cuff impingement: This condition involves the compression or pinching of the rotator cuff tendons between the bones of the shoulder joint, particularly the acromion (a bony prominence on the scapula) and the humeral head (upper arm bone). Impingement can lead to pain, inflammation, and limited shoulder mobility.

Treatment for rotator cuff injuries can vary depending on the severity and specific nature of the injury. Non-surgical approaches may include physical therapy exercises to strengthen the shoulder muscles, pain management, and activity modification.

It's essential to consult with a healthcare professional. Osteopathy and Physiotherapy are often the most effective was of treating rotator cuff pain.
