Shoulder Pain – Rotator Cuff Injury
What Is It?
Your rotator cuff is a group of muscles in the shoulder which work together as a unit. They are made up of 4 muscles called the Supraspinatus, Subscapularis, Infraspinatus and Teres Minor. These muscles are located on your shoulder blade but their tendons wrap around your shoulder joint to stabilise the shoulder and help to perform any rotation movement of your arm.
There are three main types of rotator cuff injury:
- Rotator cuff tendonosis – which is repetitive overload on the tendon causing inflammation.
- Rotator cuff impingement syndrome – where one or some of the inflamed tendons get trapped under a bone or caught in the shoulder joint.
- Rotator cuff tear – which is partial or complete tearing of one or more of the rotator cuff tendons.
What causes a rotator cuff injury?
Rotator Cuff tendonosis and impingement syndrome are often caused by an imbalance between large scapula and shoulder muscles compared to smaller stabilising muscle. This imbalance can cause an overload in one tendon which inflames. The inflammation is tendonosis and if the inflammation occurs in a part of the tendon which is close to the joint or other small bones it can impinge. Rotator cuff tears can occur from sudden force on the shoulder, usually rotation, or repetitive overload on one part of the tendon causing tearing.
What does it feel like?
Rotator cuff injuries can be felt as a sharp pain deep in the shoulder (impingement or tear) or a deep ache in the shoulder or further down the arm. Most people notice weakness in the shoulder and some experience pain or weakness only with certain positions or angles of the shoulder eg reaching into the back seat of the car.
How is it diagnosed?
Your physiotherapist can diagnose your shoulder injury from your symptoms, mechanism of injury and also with some simple tests. If your injury is severe we may need to refer you for an X-ray or ultrasound to determine the extent of your injury.
