Enthesopathy of the tuberositas radii. A diagnostic problem.

The radial tubercle is rarely the site of enthesopathy. When it occurs, symptoms and radiological images are usually typical enough for unequivocal diagnosis. We report the case of a man with atypical pain and X-rays modifications of the radial tubercle. Correct diagnosis was established by histological analysis. Better knowledge of this pathology should prevent unnecessary excision.
