Digital arthrography of the wrist: a radiographic-pathologic investigation.

An analysis of digital arthrography of the wrist was accomplished in 10 cadaveric specimens. In each case, images were obtained during a 30-sec period in which a small amount of contrast material was introduced into the radiocarpal compartment; films were reviewed with and without subtraction technique. Pathologic examination of the sectioned specimens documented the accuracy of this arthrographic method. The sequence of contrast opacification of the various compartments of the wrist and the location and size of the defects within ligamentous and cartilaginous structures were ideally seen with digital arthrography. A previously unemphasized pattern of communication, that between the midcarpal and pisiform-triquetral compartments, was seen in two instances. Digital wrist arthrography seems to represent an excellent method to evaluate the patient with suspected soft-tissue injury.
