[Lengthening technique of the ulna in Kienboeck's disease. Results after ten years].

The writers had re-examined several patients who had an operation for Kienböck disease before 1970. All had had an elongation of ulna through the same technique and no other operation for pseudarthrosis had been necessary. Eight patients were able to be examined 14.7 years after their operation (on an average). The analytical functional results were evaluated following Michon's criteria. The best results had been obtained as far as pain and strenght of the wrist were concerned, yet those obtained on mobility proved disappointing. X-Rays showed a lunatum keeping its shape 6 times out of 8 and an almost constant development of arthrosis. The use of the technique is questioned in the treatment of Kienböck disease.
