Adamantinoma of the Ulnar Shaft Reconstructed With a Vascularized Free Fibula.

Abstract

We describe a 36-year-old man with a long-standing diagnosis of ulnar fibrous dysplasia with associated fracture of the ulna. He presented with a growing and increasingly tender forearm mass and was diagnosed with adamantinoma of the ulna, for which he underwent wide resection of the ulnar diaphysis followed by reconstruction with a vascularized fibula autograft. This case serves to emphasize the importance of performing a stepwise workup for the diagnosis of osseous neoplasms even in cases with long-standing diagnoses.
