Dislocated Shoulder

What causes a dislocated shoulder?

This is normally an acute injury, caused by direct or indirect trauma with a sudden onset of severe pain, and often a feeling of the shoulder 'popping out'.

How can you tell a dislocated shoulder?

Often the shoulder will appear obviously different to the other side, and if there is any nerve damage the sensation might also be altered.  Normally you will have quite severe pain associated with a dislocation.

Other types of Glenohumeral Dislocation / Shoulder Disclocation

Usually shoulder dislocations are anterior – that is, the head of the humerus moving forwards.  This can happen in the opposite direction (although this is less likely), with the head of the humerus being forced backwards.  This is known as a 'posterior dislocation', and is more common following a fit, or if falling on an outstretched hand.  The arm will tend to be held into the body (in internal rotation and adduction), and as this is slightly harder to reduce, X-Rays are very important.  If possible a Lateral and/or Axillary view is needed to check for fractures.

The configuration of the shoulder makes it very rare for the shoulder to dislocate in any other direction.  If this is suspected, there is a very high possibility that there are associated fractures in the joint, and reduction should not be attempted without X-Ray guidance

How is a posterior dislocation different?

Posterior dislocation is far less common and occurs as a result or direct trauma to the front of the shoulder or a fall onto an outstretched arm that is rotated inwards or adducted (towards or across the body). It can also be caused by electric shock.
