Shoulder dislocations

The shoulder is a fascinating joint with incredible flexibility. It is connected to the body via a complex system of muscles and ligaments. Most of the other joints in the body are very stable, thanks to the structure of the bones and ligaments surrounding them. However, the shoulder has so much movement and flexibility that stability is reduced to allow for this. Unfortunately, this increased flexibility means that the shoulder is more vulnerable to joint dislocations.

What is a dislocation and how does it happen? 

As the name suggests, a dislocated shoulder is where the head of the upper arm moves out of its normal anatomical position to sit outside of the shoulder socket (the glenoid).

Some people have more flexible Joints than others and will, unfortunately, have joints that move out of position without much force. Other people might never dislocate their shoulders unless they experience a traumatic injury that forces it out of place. The shoulder can dislocate in many different directions, the most common being anterior or forwards. This usually occurs when the arm is raised and forced backward in a ‘stop sign’ position.

What to do if this happens

The first time a shoulder dislocates is usually the most serious. If the shoulder doesn’t just go back in by itself (spontaneous relocation), then someone will need to help to put it back in. This needs to be done by a professional as they must be able to assess what type of dislocation has occurred, and an X-ray may need to be taken before the relocation happens.

A small fracture can also occur as the shoulder is being put into place, which is why it is so important to have a professional perform the procedure with X-Ray guidance if necessary.

How can physiotherapy help?

Following a dislocation, your physiotherapist can advise on how to allow the best healing for the shoulder. It is essential to keep the shoulder protected for a period to allow any damaged structures to heal as well as they can.

After this, a muscle strengthening and stabilization program can begin. This is aimed at helping the muscles around the shoulder to provide optimum stability and prevent future dislocations.
