Irreducible isolated dislocation of the radial head in a skeletally mature teenager. A case report.

Isolated dislocation of the radial head is an uncommon injury. This injury has been reported in children; in the skeletally mature it is extremely rare. An irreducible dislocation has been previously reported in a young child, but no case has to date been reported in an adult. The present case is reported to demonstrate this rare injury and to suggest a possible explanation for the cause of the irreducibility.
