Radial head subluxation.
Radial head subluxation occurs when the thin, weakly attached annular ligament of the forearm becomes entrapped in the radiocapitellar space after marked traction on the extended, pronated arm. It is the most common musculoskeletal injury in children between two and five years of age. Awareness of this condition permits easy diagnosis and rapid treatment by simple manipulation.
