These injuries are due to violence occurring around the joints. The joint is disrupted and the bones moved from their normal position.
The earlier medical attention is sought, the easier it is to reduce the dislocation. Once the joint has been displaced for some time, rather strong muscular spasm is present, and it may be necessary to anaesthetise the patient to reduce the dislocation.
Simple dislocation of the finger joints can often be replaced by firm pulling of the end of the finger, and holding the wrist with the other hand.
It may be easier to do so immediately after the finger has been dislocated, and many sportsmen are quite adept at fixing their colleagues’ dislocated fingers.

An operation is available to correct recurrent dislocation of the shoulder.
