The importance of clinical semiotics and instrumental investigations in the diagnosis and surgical treatment of osteoid osteoma. A report of 6 cases

The author emphasize the importance of a complete examination, including history, symptomatology and instrumental tests in the diagnosis of osteoid osteoma (O.O.). This lesion is often difficult to diagnose, particularly at unusual sites. However, by the use of accurate radiography, stratigraphy, bone scan and CAT, a pre-operative accurate diagnosis is usually possible. The authors emphasize the importance of the least invasive surgical approach and the complete removal of the lesion with generous curettage. This is not always easy, as illustrated in the present study, which includes atypical sites, sometimes in delicate anatomical situations. They also illustrate a particular method used for removal.
