(Syn. Subluxation of Superior/Inferior Radio ulnar Joint)

This is a painful condition of the elbow affecting children below the age of 5 years. It is caused by a pull on the arm with the forearm in a state of internal rotation. It is not the fall but the prevention of fall that causes the problem. Usually it occurs when the mother pulls the child by arm to put him on the other side while turning in bed. Sometimes when the child has a tendency to fall from the bed he, holds the bed sheet to prevent the fall, the whole body weight gives the momentum to internal rotation at the elbow joint and the upper/lower radio ulnar joint is partly dislocated.

It is a very painful condition the affected limb appears to be paralyzed

It is an orthopaedic emergency and the child should be taken to an orthopaedic surgeon or to the casualty department of a hospital immediately.

The X-ray usually does not show any abnormality.

Reduction of the joint displacement is easy. A cuff and collar sling is usually adequate.

If the condition becomes recurrent, a plaster may have to be applied for 2-3 weeks.

No medicine is required.
