[Vertebral osteochondroma and trauma: a possible etiopathogenic correlation]

Three cases of vertebral osteochondroma are shown. The tumor was localized in the dorsal tract in two cases and in the lumbo-sacral junction in the other one. We found in all the cases, as a common anamnestic point, a clinical history of trauma. The etiopathological hypotheses are discussed and the hypothesis of a possible correlation between trauma and metaplastic osteochondromatosis is presented.
