Dislocated shoulder

Also called Shoulder dislocation

A dislocated shoulder is when the ball at the top of the upper arm bone comes out of the shoulder socket. It is usually caused by a fall onto an outstretched arm or a blow during contact sport. It is very painful and should be put back in place by a doctor, usually in an emergency department.

What it is

After it is put back, the arm is rested in a sling for a short time, followed by physiotherapy. Full recovery usually takes 12 to 16 weeks.

Young, active people are more likely to dislocate again, and surgery to stabilise the shoulder may be offered.

Common signs

  • Severe pain in the shoulder
  • Being unable to move the arm
  • The shoulder looking square or out of shape
  • Swelling and bruising
  • Numbness or tingling in the arm

How it is usually diagnosed

  • Examination
  • X-ray before and after putting it back
  • MRI or CT if it keeps dislocating

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • X-ray reports
  • Emergency department letters
  • Physiotherapy plans
  • Dates of any repeat dislocations
  • Operation notes, if any

Questions to ask your doctor

  • Is there any damage to the bone, ligaments or nerves?
  • When can I return to sport or work?
  • Do I need surgery to stop it happening again?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Do not try to put it back yourself: go to an emergency department
  • A cold, pale or numb arm: call 112
