What is a Shoulder Dislocation or Subluxation?

A shoulder dislocation is where the head of the humerus (top of the arm bone) is forced out of the glenoid (shoulder socket). This injury requires an external force for the shoulder to be relocated back to the joint. A subluxation of the shoulder is where the head of the humerus is forced out of the joint but able to relocate on its own.

What are the Signs and Symptoms of a Shoulder Dislocation?

+ Feeling of the shoulder ‘popping’ out of the joint

+ Pain in the shoulder

+ Unable to lift the arm above shoulder height (90 degrees)

What is the Treatment of a Shoulder Dislocation?

The shoulder must first be relocated which is often performed by an Emergency Doctor or Paramedic. Once the shoulder is relocated the Physiotherapist will assess whether an MRI and x-ray is required. An MRI and x-ray will show if there’s been any damage to the supportive structure’s such as the labrum, and rotator cuff and bone.

If the Physiotherapist is satisfied, then rehabilitation will be aimed at strengthening the rotator cuff as this prevent a secondary dislocation. When a shoulder is dislocated for a second or third time then a surgical intervention may be required such as a lateral jet or stabilisation procedure.
