[Indications for computerized tomography of the wrist joint and carpal bones].

Twenty-nine patients with thirty-one fractures of the distal radius and persistent pain or disability had computed tomography of the radio-carpal and distal radioulnar joint. We found incongruity of the distal radio-ulnar joint in six patients. Ten patients had a rotational malalignment in supination. Seven patients suffered from rotational malalignment in pronation. The ability to quantify rotational malalignment and to have images of the degenerative arthritis following these disorders without superimposition aids in selecting surgical treatment.
