Palmar dislocation of the radiocarpal joint.

Radiocarpal dislocation, with or without damage to the radial styloid process or to the distal radial rim, is extremely rare. Review of the literature reveals much confusion on the proper classification of radiocarpal dislocations or fracture-dislocations. A case of radiocarpal dislocation is reported, the classification is discussed, and a critical review of earlier reports is presented.
