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.

congenital dislocation of the hip a former name for developmental dysplasia of the hip.

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

Patient discussion about dislocation.

Q. I have dislocated my shoulder for the 3rd time, what I can do in order to avoid surgery? This is an old injury that keeps coming back. I have been dealing with this unstable shoulder for more than 5 years now. In the past few weeks I've visited 3 different doctors, all said that I can't avoid surgery this time or it with keep on dislocating spontaneously. Even though the docs are thinking that it's a lost cause,I got a really good feeling that I will manage to fix my shoulder 100% with no surgery involved. Is there any known therapy I should try before admitting to my surgery?

A. After the pain and swelling go down, your doctor may prescribe physical therapy. This helps restore your shoulder's range of motion and strengthens your muscles. In addition, physical therapy may also help prevent future dislocations.
If your shoulder dislocation recurs often, a brace can sometimes help. However, if physical therapy and a brace do not work, then you may need surgery to repair or tighten torn or stretched ligaments. This will help keep the joints in place.

Q. My neighbor's kid had a lens dislocation due to Marfan's disease. Is this a contagious thing? My neighbor's have a sweet 8 year old boy. he had a lens dislocation due to a connective tissue disease named Marfan (I think that the name). It sounds like a very serious condition. My boy is playing with this kid several hour a week. should I take him to the GP to see that his is not infected with this marfan thing?

A. Don't worry. Marfan's syndrome is a connective tissue disease that is genetic. This means that You can't "get" this disease. Either you are borne with it or you will never suffer from it.
lens dislocation is a known symptom of marfan's syndrome, and is not connected to infectious diseases.
