congenital dislocation of the hip

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.Shoulder dislocation.complete dislocation one in which the surfaces are entirely separated.compound dislocation one in which the joint communicates with the outside air through a wound.congenital dislocation of the hip a former name for dysplasia of the hip" >developmental dysplasia of the hip.pathologic dislocation one due to disease of the joint or to paralysis of the muscles.simple dislocation one in which there is no communication with the air through a wound.
