dislocation [dis″lo-ka´shun]
displacement of a bone from a joint; called also luxation. The most common ones involve a finger, thumb, shoulder, or hip; less common are those of the mandible, elbow, or knee. Symptoms include loss of motion, temporary paralysis of the joint, pain, swelling, and sometimes shock. Dislocations are usually caused by a blow or fall, although unusual physical effort may also cause one. A few dislocations, especially of the hip, are congenital, usually from a faulty construction of the joint, and are best treated in infancy with a cast and possibly surgery.
A dislocation should be treated as a fracture when first aid is administered. First aid includes checking for a pulse distal to the location and keeping the patient as still as possible. The patient is moved as a whole unit on a long board or a stretcher. As soon as possible the dislocation must be reduced by a surgeon.
