Congenital pseudarthrosis of the ulna

We report a case of congenital pseudarthrosis of the ulna along with generalized neurofibromatosis (type I). The patient had a good clinical outcome after single-bone forearm reconstruction. In the setting of radial head dislocation following long-standing congenital pseudarthrosis of the ulna, single-bone forearm reconstruction is a viable option. It prevents the loss of hand function by the effective shortening of flexor tendons and spares movements of the humeroulnar and radiocarpal joints.
