Introduction to Various Shoulder Injuries

Our shoulder is a very delicate and complex component of our body that is kept together by bones, tendons and muscles. A shoulder injury is very painful and can cause a lot of discomfort and inconvenience to us. There are many different kinds of shoulder injuries and they are caused by different reasons such as strain, cyclic motion and injuries.

Rotator cuff strain

Rotator cuff strain is a common injury which is due to an inflammation of a tendon located in the shoulder. 4 muscles make up the rotator cuff namely the supraspinatus, infraspinatus, teres minor and subscapularis. The most common reason for a rotator cuff strain is because of insufficient warm up prior to the start of an activity or overload of the muscles. Poor posture and accidentally falls causing you to land on your shoulders can also cause rotator cuff strain. A strain can slowly evolve into a tear if it is left untreated. For immediate treatment, RICE is sufficient. If symptoms get worse, consult a doctor immediately.


Our shoulder joint is an unstable joint due to the functions of it. The shoulder joint can be described as a ball and socket joint and the ball is the arm bone and the socket is the shoulder blade. It is the part of our body which has the most motion compared to all other joints. It is because of this fact that causes instability to the area. Instability can get worse when the ligaments are overstretched and are unable to hold the ball and socket firmly in place. Dislocation of the shoulder joint can occur due to injuries or trauma, causing the ball to go out of the socket.


Impingement of the shoulder joint occurs when the supraspinatus, bicep tendons, bursa and subacromial are compressed over time, causing inflammation. It is due to repeated overhead usage of the shoulder joints. Activities which causes these include swimming and overhead press. To prevent impingement, you should allow adequate rest period between activities and strengthening of the rotator cuff muscles to allow it to take more load.


Our muscles are connected to the bones through connective tissues called tendons and tendonitis is an inflammation of these tendons. The tendons that are most susceptible are the biceps tendons as well as the rotator cuff muscles. Tendonitis are usually caused by overuse, pulling or over-compression of the tendons, causing pain, tenderness and discomfort. To prevent tendonitis, ensure that proper warm up of the whole body is done and add on weights gradually to allow the body to adapt to it.

Above are 4 shoulder injuries that are frequently experienced by people. Our shoulder is an integral part of our daily life and any injuries to it will cause great discomfort and inconvenience our lives. They can be easily reduced by doing proper stretching, gradually load up and sufficient rest periods between activities.
