[Determining the position of the prosthesis using arthrography of the wrist joint]

During the last twelve months twelve patients with different silicone prostheses of the wrist region underwent examination with arthrograms two to twenty-four months after the operation. The arthrography showed the relation of the implant to its surrounding structures. For either radiocarpal or intercarpal arthrography a very distant access was used. In eight patients the prostheses were surrounded entirely by contrast medium. There was no contrast-medium on one side of the implant in two patients. In one patient a complete disconnection from the capsule to the site of the prosthesis was seen. In one other patient there was evident shrinking of the capsule. Wrist arthrography was very helpful for the evaluation of further clinical proceeding and control of wrist-function.
