Common Shoulder Injuries
-
Rotator Cuff Injuries
Rotator cuff injuries are complex, and can vary from repetitive strain causing tendonopathy, acute injuries which can cause partial or full thickness tears, or overuse which can cause chronic tears of the fibres that help stabilise the shoulder. These often are caused by falling on an outstretched hand, sporting injuries out on the field or in the gym, lifting something awkwardly from an overhead position, or when pushing/pulling a heavy object.
-
Shoulder Impingement
This is a common symptom that stems from an irritable shoulder due to potential inflammation of certain structures (such as bursitis), rotator cuff injuries, muscle or tendon strains, labral (cartilage) injury, bone injury, or instability of the joint from previous trauma.
-
Shoulder Dislocation
Dislocations commonly occur when falling on an outstretched hand, which often occurs in contact sports. The shoulder can dislocate more commonly anteriorly (front), and less commonly posteriorly (behind), which can lead to associated injuries to surrounding structures of the shoulder such as the labrum and ligaments. This can long-term cause instability and requires surgical opinion.
-
Frozen Shoulder (Adhesive Capsulitis)
Often associated with high levels of pain and stiffness, frozen shoulder can significantly limit function, and while in some incidents trauma can trigger it, it can often occur without any clear reason
-
AC Joint Injuries
The acromioclavicular (AC) joint, located at the tip of the shoulder, is typically injured from direct impact such is in a rugby tackle, or falling directly on the shoulder. This injury is associated with high levels of pain, and can cause limitations in strength and mobility, depending on the grade of injury to the surrounding bone and ligaments.
