Less swelling makes subsequent re-setting of the joint easier. Elevating the affected part of the body can be helpful.

Dislocated joints must only be re-set ("reduced") by a doctor. An X-ray must be taken to see if there is any additional damage. Wherever possible, the reduction should be carried out within a few hours of the injury. In the case of minor dislocations, for example of finger joints, this is performed under local anaesthesia. In shoulder dislocations, on the other hand, general anaesthesia is chosen. After the reduction, another X-ray is taken to check that the joint surfaces are in correct alignment with each other.

The joint is then immobilised for 8 to 10 days using elastic bandages, splints or a plaster cast. To prevent renewed dislocation, this is followed by careful mobilisation, because prolonged immobilisation can result in shrinkage of the capsule.
