Isolated dorsal dislocation of the distal radioulnar joint: A case report.

Isolated acute dislocation of the distal radioulnar joint is a rare lesion, and in 50 % of cases goes unrecognized; it may be palmar or dorsal. Its diagnosis is suspected when the wrist is traumatic, painful, with limited pronosupination and no fracture on radiological examination. Treatment is aimed at preventing the development of chronic instability and/or arthrosis, and consists of reduction followed by immobilization.
