The shoulder is made up of several joints that combine together with tendons and muscles to allow a wide range of motion in the arm. This wide range of motion may lead to problems with instability or impingement of the soft tissue or bony structures in your shoulder, often resulting in pain. Your rotator cuff is one of the most important structures in your shoulder to provide mobility and stability. The rotator cuff is made up of four small muscles and their tendons that cover the head of the upper arm (humerus) and keep it in the shoulder socket.
Your shoulder is made up of three bones: your upper arm bone (humerus), your shoulder blade (scapula), and your collarbone (clavicle).
The head of your humerus fits into a rounded socket in your shoulder blade. This socket is called the glenoid. A combination of muscles and tendons keep your humerus centered in your glenoid. These tissues are called the rotator cuff, and they cover the head of your humerus and attach it to your scapula.
You may only feel pain with certain movements, or all of the time. The pain may be temporary or it may continue and require medical diagnosis and treatment.
Most shoulder problems fall into four major categories:Tendon inflammation (bursitis or tendonitis) or tendon tear, instability, arthritis, fracture (broken bone)
A thorough physical examination will usually establish the diagnosis of shoulder pain and guide your individualized shoulder rehab or sports rehab. The underlying cause of shoulder pain will help direct the treatment and plan of care. Most instances of shoulder pain can be successfully treated conservatively (physical therapy, chiropractic, massage, etc.) although some injuries may require surgerical intervention.
