A dislocation occurs when a bone is displaced from its normal position at a joint. It may be suspected when a joint injury results in abnormal shape, limited movement, and severe pain that worsens with motion. Swelling and deformity are common.

Dislocations closely resemble fractures, except there is no grating of bone ends. Both conditions may occur together.

First aid
If a wound is present, cover it to control bleeding and prevent infection.

Do not attempt to reposition (reduce) the dislocation, as a fracture may also be present and manipulation may worsen the injury.

Immobilize the joint using the same techniques as for fractures. Monitor for impaired circulation and loss of sensation. If circulation is compromised and no pulse is felt, gently adjust the limb to restore blood flow and maintain that position.

Transport the casualty in the most comfortable position—usually sitting for upper limb injuries and lying down for lower limb injuries.
