congenital dislocation of the hip

dislocation /dis·lo·ca·tion/ (dis″lo-ka´shun) displacement of a part.

complete dislocation one completely separating the surfaces of a joint.

compound dislocation one in which the joint communicates with the air through a wound.

congenital dislocation of the hip developmental dysplasia of the hip.

pathologic dislocation one due to paralysis, synovitis, infection, or other disease.

simple dislocation one in which there is no communication with the air through a wound.

subspinous dislocation dislocation of the head of the humerus into the space below the spine of the scapula.

congenital dislocation of the hip (CDH),

an orthopedic defect, present at birth, in which the head of the femur does not articulate with the acetabulum as a result of an abnormal shallowness of the acetabulum. Treatment consists of maintaining continuous abduction of the thigh so that the head of the femur presses into the center of the shallow cavity, causing it to deepen. Also called congenital dysplasia of the hip, congenital subluxation of the hip. See also Frejka splint.

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.
