The clinical history and technical investigations for diagnosing an osteoid osteoma are well described in the literature, although the presentation is not always typical. An osteoid osteoma of the coronoid process with diminished forearm rotation is unusual. This in contradistinction to the more common flexion-extension deficit.
We report a case of a man with a clinical supination deficit of the forearm due to a radiographically confirmed osteoid osteoma of the coronoid process at the proximal radioulnar joint site.
