A dislocation occurs when there is permanent displacement of the bony ends of a joint. The symptoms of dislocation are similar to that of a fracture, so intense pain, deformity, swelling, and inability to move. It is necessary, first of all, to check the CSM. Immobilize the part as if it were fractured and send the patient to the emergency room.
