The authors report a rare case of an isolated palmar dislocation of the distal radio-ulnar joint (DRU). Diagnosis was easily established in emergency even though this lesion is usually unknown in 50 per cent of cases, according to literature. A surgical approach was necessary because of irreducibility of the lesion: ulna and radius were hitched with no other anatomical interposition. Treatment succeeded and the functional result was good with only 25 degrees of loss of pronation. This suggests a commentary on DRU joint physiology, on the mechanism of dislocation, and on the methods of treatment.
