Abstract

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.

Figure

• 

  Fig. 1 Anteroposterior and lateral radiographs of the left forearm of a 6-year-old boy with left elbow deformity and shortening show a pseudoarthrosis of the ulna and atrophic change of the distal ulna with a chronic radial head dislocation.

• 

  Fig. 2 Eighteen and half years postoperatively, severe cubitus valgus deformity was noted (A), and a corrective dome osteotomy was performed at the proximal forearm bone (B).

• 

  Fig. 3 Clinical photographs of the patient at more than 20-year follow-up shows 7° of extension and 141° of flexion of the left elbow and 40° of pronation and 40° of supination.
