A joint dislocation is when the bones that make up a joint are separated and forced out of their usual position. Most joint dislocations are caused by injury or overuse.
Any joint in the body can be dislocated, but the most commonly affected joints include:
Some injuries do not lead to a complete joint dislocation; instead, the bones in the joint are partly pushed out of place. This is a partial dislocation, also known as a subluxation.
Joint dislocations tend to happen suddenly. If you have a dislocated joint, it is likely to be very painful because the tissues around the joint will usually have been stretched and torn.
The pain will often be worse on moving the joint and you may feel scared to try and move it.
Other symptoms of a joint dislocation include:
Joint dislocations are most commonly caused by physical injury to the joint. This may be from direct force, general wear and tear, or overuse (e.g. athletes overtraining).
Double-jointed people (joint hypermobility) and those with certain disorders such as Ehlers-Danlos syndrome are more prone to dislocations. Younger men who play sport are also at a higher risk of joint dislocations, as are older women - due to their increased risk of falls.
A doctor will usually examine the affected joint if a dislocation is suspected. You may need imaging tests to confirm the diagnosis and identify any fractures.
These can include:
Treatment for a joint dislocation usually involves returning the joint to its normal position. This should be done in a hospital and by a health professional.
Do not try to put the joint back in yourself as this could damage the nerves, tissue and blood vessels around the affected joint. Instead, go to the emergency department or call an ambulance if you cannot walk or have severe injuries.
While waiting for medical attention, try the following self-care measures.
Before a dislocated joint is put back into place, you may need imaging scans, such as X-rays, to check for broken bones.
Putting a dislocated joint back into its normal position is known as a reduction. You may need painkillers or anaesthetic to numb the area before the reduction.
During a reduction, a doctor moves the affected joint back into place by pulling or turning the limb it is connected to. This can usually be done without surgery, but in some cases, you may need surgery.
After the joint is back in place, it should be kept from moving (immobilised) to allow it to heal. This is typically done using 1 of the following:
Once a dislocated joint has been returned to its normal position, treatment often involves rehabilitation. This usually involves physiotherapy to help restore movement, strength and normal function of the injured joint.
How quickly you recover from a joint dislocation tends to depend on the joint you injured, the severity of the dislocation, your age and if you have any other health conditions.
You should only return to sport and exercise once you have fully recovered.
A physiotherapist can work with you to develop an exercise programme to help you gradually return to physical activity and to reduce the risk of dislocating the joint again.
Speak to your doctor or physiotherapist before beginning exercise after a joint dislocation. They can let you know if (and when) it is safe to do so.
