Computed tomography and sectional radiography and photography were performed on eight cadaveric wrist specimens in order to define the soft tissue structures of the normal wrist. Three specific levels were analyzed in detail: the levels of the distal radioulnar joint, of the pisotriquetral joint, and of the hook of the hamate. All soft tissues, with the exception of arteries and veins, were well demonstrated with computed tomography. In particular, the contents of both Guyon’s canal and the carpal tunnel could be delineated. The position of the extensor carpi ulnaris tendon and sheath could also be evaluated. Contrast opacification of the flexor tendon sheaths and palmar synovial sacs did not contribute to the analysis. Computed tomography appears to be an important imaging modality in the evaluation of significant clinical problems, including the carpal tunnel and ulnar tunnel syndromes and subluxation of the extensor carpi ulnaris tendon.
