Wrist arthrography allows direct visualization of the cartilage and synovial structure not seen in plain film. Arthrography of the wrist is valuable in evaluating patients with persistent wrist pain and limitation of motion after trauma. Wrist arthrography was performed in the evaluation of 30 patients with rheumatoid arthritis(2 cases), ganglions (12 cases), and wrist trauma(16 cases), and contrast media was injented in radiocarpal joint. The arthrographic findings were analyzed, and the results were as follows: In 16 patients with wrist trauma, 12 cases(75%) of compartment communication was seen including communication with distal radioulnar joint(44%), midcarpal joint(69%), and common carpometacarpal joint(63%). Of the total 30 patients, the pisiform-triquetral joint communicated with the radio carpal joint in 9 cases(30%). In 16 patients with trauma, the findings of post-traumatic arthritis included tendon communications(50%), irregualr synovium(31%), and rupture of the joint capsule(25%). There was no lymphatic filling. Of 3 scaphoid fracture patients without bony callus formations, fibrous union was verified in one patient and nouncion in 2. Of 12 patients with ganglion, communication between the ganglion adn radiocarpal joint was seen in 2 cases and no communication in 10 cases.
