[Atypical osteodystrophy of visceral origin (author's transl)].

: The authors report a case of atypical osteodystrophy of visceral origin (uretero-sigmoid by-pass for bladder exstrophy) which was characterized by the association of osteocondensation and looser-Milkman lines. They emphasize the rareness of osteodystrophy after uro-digestive by-pass and the exceptional character of the osteocondensation.
