title: [Congenital pseudarthrosis of the forearm. Report of two cases and review of the literature].
abstract: Congenital pseudarthrosis of the forearm represents a rare entity which is often associated with neurofibromatosis type I. Isolated pseudarthrosis of the ulna is the most frequent deformity, followed by pseudarthrosis of the radius and both forearm bones. The treatment of these deformities remains difficult: conventional bone grafts rarely lead to complete fusion. The reconstruction by a vascularized fibular graft represents the treatment of choice if the radial head is not dislocated. This procedure allows restoration of a balance between radius and ulna during growth. The presence of a vascularized graft enhances the potential for bony fusion in a fibrous environment. In cases of isolated ulna pseudarthrosis, a luxation of the proximal radial epiphysis may occur when the ulnar deformity increases with time. The single-bone forearm represents a salvage procedure that creates a stable upper limb with a satisfactory wrist and elbow function. The two clinical cases of a pseudarthrosis of both forearm bones and of an ulna pseudarthrosis are presented.
