[Unusual course of scapho-capitate syndrome]

The scapho-capitate-syndrome has been defined as combined fractures of the scaphoid and capitate with rotation of the proximal fragment of the capitate through 90 or 180 degrees. Most injuries are due to falls from heights or car accidents. Only 26 cases of the scapho-capitate fracture syndrome have been reported since 1937. In nearly one third of these cases, there was a delay of more than two weeks in diagnosis. We report a case of a young man in whom the complex injury was erroneously diagnosed as an isolated fracture of the scaphoid. The scaphoid fracture was treated by a screw and healed well. Although the patient suffered persistent pain in his wrist, the correct diagnosis was made only two years later. During revision operation we found the head of the capitate still inverted and with marked signs of avascular necrosis and destruction of the lunate cartilage. The avascular fragment was removed and substituted by a graft from the iliac crest. The capitate and lunate were fused.
