[Post-traumatic osteoid osteoma. Apropos of 2 cases and review of the literature]

Abstract

Two cases of osteoid osteoma which became clinically apparent after a prolonged silent period are reported. One was located in the tibia in a 30-year-old female and the other in the femur in a 26-year-old male. Both developed after a surgical procedure, at the site of the operation; one was located on the track of an internal fixation screw. Diagnosis was delayed despite the suggestive timing of the pain; isotopic scanning, CT scan and angiography provided suggestive data and diagnosis was confirmed by histologic studies. A review of the literature found 13 other cases meeting the following criteria: initial trauma, silent period, suggestive pain, discovery of an osteoid osteoma at the site of the trauma, and recovery following surgical treatment. The role of the trauma is discussed.
