Scaphoid exostosis and radio-carpal osteoarthrosis

We report seven patients (eight wrists) with osteoarthrosis of the wrist associated with an exostosis arising from the dorsal aspect of the scaphoid. We believe that the exostosis is secondary to impingement of the scaphoid on the radial styloid process and is a consequence rather than a cause of osteoarthrosis. Conservative management is advised.
