Scaphoid-trapezium-trapezoid subluxation.

A case of scaphoid-trapezium-trapezoid subluxation (STTS) is presented. This injury has only been described three times before. More interest in injuries to the ligaments of the wrist will probably show a greater frequency of (STTS). In cases of pain on the radial border of the wrist due to trauma and with normal routine radiographs, one would recommend supplementary radiographs with the wrists kept in maximal ulnar deviation. The treatment of (STTS) is discussed.
