[Rare lesion of the median nerve caused by elbow dislocation with avulsion of the epicondylus humeri medialis in childhood].

A case of posterior dislocation of the elbow complicated by intraarticular entrapment of the median nerve is reported. Sixteen cases have previously been described in the literature. The mechanism of the injury is discussed. Early exploration of the nerve is advised when signs of median nerve deficit persist following reduction of the dislocated elbow.
