One-Bone Forearm Procedure for Acquired Pseudoarthrosis of the Ulna Combined with Radial Head Dislocation in a Child: A Case with 20 Years Follow-Up

This report describes a 6 year-old boy who was treated with one-bone forearm procedure for acquired pseudoarthrosis of the ulna combined with radial head dislocation after radical ulna debridement for osteomyelitis. At more than 20 years of follow-up, the patient had a nearly full range of elbow movements with a few additional surgical procedures. Pronation and supination was restricted by 45degrees, but the patient had near-normal elbow and hand functions without the restriction of any daily living activity. This case shows that one-bone forearm formation is a reasonable option for forearm stability in longstanding pseudoarthrosis of the ulna with radial head dislocation in a child.

Congenital Pseudarthrosis of Ulna: A Case Report / 대한정형외과학회잡지

Congenital pseudarthrosis of the ulna is an extremely rare disease that is usually associated with neurofibromatosis. Various treatments have been introduced such as conservative treatment, nonvascularized bone graft, free vascularized fibular graft, one bone forearm procedure and the Ilizarov technique. However, it is difficult to obtain bone union. We report a case of pseudarthrosis of the distal ulna that was treated by a one bone forearm procedure.
