Affected by or showing the presence of an exostosis; having bony growths projecting from a bone surface.
From exostosis + '-ed' (past participle/adjective forming suffix). Medical terminology used since the 19th century to describe pathological bone conditions.
Medieval warriors and athletes sometimes developed exostosed bones from repeated trauma—basically their bones would grow painful lumps as an overzealous healing response, kind of like scar tissue but made of actual bone.
