Congenital forearm pseudarthrosis is a rare clinical entity which is often linked with neurofibromatosis type 1. Involvement of both bones associated with dislocation of the radial head is extremely rare, and few cases have been reported in the literature. We present a case of an 8-year-old girl with neurofibromatosis type 1 and pseudarthrosis of both forearm bones associated with dislocation of the radial head. She underwent resection of the distal ulna, excision of the pseudarthrosis, and a one-bone forearm procedure fixed with a plate. The first surgery failed to achieve bone union, and she required revision with bone grafting, plate removal, and intramedullary nailing. After the second surgery, she had a stable forearm that was shortened approximately 7 cm. At the last follow-up, 4 years postoperatively, the patient is asymptomatic, and has a mild limitation of wrist flexion-extension. The one-bone forearm is a reasonable option for forearm pseudarthrosis with radial head dislocation in children. This salvage procedure produces a stable upper limb with a satisfactory wrist and elbow function.
