Congenital pseudoarthrosis of the radius in Neurofibromatosis Type 1: An entity not to be missed!

Congenital pseudoarthrosis of the radius is exceedingly rare. We report an isolated pseudoarthrosis of the radius in a five-year-old girl child with Neurofibromatosis type-I (NF–I). She underwent excision of the pseudoarthrosis tissue, ulna osteotomy, iliac crest cortico-cancellous bone grafting, and K wire fixation of both bones. A sound union of the radius and the ulna was achieved after 4 months. At two-year follow-up, mild shortening of the forearm persisted with maintenance of sound union of both bones. Accurate diagnosis of the condition is central in avoiding complications and the need for complex surgical procedures.
