title: Digital wrist arthrography: precision in determining the site of radiocarpal-midcarpal communication.
abstract: Wrist arthrography is used for precise determination of posttraumatic interosseous ligament tears. Digital subtraction arthrography adds to the precision in diagnosis of the site of radiocarpal-midcarpal communication. Using the technique for digital subtraction wrist arthrography outlined in this paper, the classic scapho-lunate and lunate-triquetral perforations were delineated. Scaphotrapezium and triquetral-hamate interosseous ligament perforations were also delineated. The added diagnostic precision of digital subtraction at the first injection was useful in planning the correct surgical procedure.
