Work in progress: postarthrography computed tomography of the wrist: evaluation of the triangular fibrocartilage complex

This report reviews a work in progress evaluating the use of postarthrography computed tomography (CT) of the wrist in assessing triangular fibrocartilage complex abnormalities. Twenty-two triangular fibrocartilage complex perforations in 119 patients were identified with both multiple compartment arthrography and postarthrography CT. To obtain a double contrast image of the triangular fibrocartilage complex, the postarthrography CT examinations were performed after multiple compartment arthrography and the injection of air into the radiocarpal compartment. The site of triangular fibrocartilage complex perforation could be identified (radial versus peripheral) as could degenerative changes and internal derangements such as chondrocalcinosis. We did not, however, find any information not provided by arthrography that would have changed the course of management. At this time there is no clinical role for postarthrography CT in the evaluation of triangular fibrocartilage complex derangements.
