Distal Radioulnar Joint Instability

Distal Radioulnar Joint Instability occurs when articular contact between the two forearm bones at the wrist follows an abnormal path in motion.

Sometimes occurring in gymnasts, causes include damage to the ligamentous structures that comprise the joint or irregular alignment of the joint surfaces due to fracture or severe wrist sprain. The result of either sudden trauma or recurrent strain, Distal Radioulnar Joint Instability manifests itself in painful and limited ability to rotate the forearm.

Simple instabilities can be treated with rest, splinting and physical therapy, whereas more severe cases may require arthroscopically assisted reconstructive surgery.
