[Osteotomies of the forearm in the treatment of ulnar dysmelia (author's transl)].

The syndrome and classification of ulnadysmelia--which shows considerable analogy to fibuladysmelia--is described on the basis of two cases. The therapy of the milder form of this deformation which includes our two patients is discussed. Correction osteotomy of the bones of both forearms with excision of the radial head is recommended for inveterate cases. In younger children, a result which is both cosmetically and functionally successful can be achieved by lenghtening osteotomy of the ulna. The operation is to be repeated if necessary.
