What are dislocated joints?

A dislocated joint happens when bones are partly or completely pulled out of their normal position. Joints can dislocate when a strong force wrenches or pulls the bone into an abnormal position. Common dislocations include the knee, jaw, ankle, and fingers and thumbs.

Signs and symptoms

Someone with a dislocated joint may:

  • have swelling and bruising around the joint and it may look shorter, bent, or deformed.

  • complain of a severe, sickening pain

  • be unable to move the joint.

What to do

  1. 1

    Advise the casualty to stay still. Help them to support their dislocated joint in the most comfortable position. Offer simple pain relief such as paracetamol, if they can take it.

    • Do not try to put the dislocated bone back into its socket, as this may cause further injury.

  2. 2

    Stop the joint from moving.

    • If you think they have dislocated their shoulder or elbow, support the injured arm using a sling. To give comfort and support, tie a broad-fold bandage (wide bandage) around the chest and the sling. If a hand or arm is injured, remove any watches in case of swelling.

    • If you think they have dislocated their ankle, knee, or hip joint, support the injured leg using padding and broad-fold bandages.

    • With a lower limb joint, make sure they don't put any weight on it.

  3. 3

    Send the casualty to hospital. Call 999 or 112 for emergency help if you can’t take them yourself.

  4. 4

    While waiting for help, treat for shock if necessary. Monitor their level of response.

    • Do not raise an injured leg. Only raise the uninjured leg.

  5. 5

    Check the circulation beyond any bandages every 10 minutes and loosen if necessary.
