Osteoid osteoma diagnosis and management with low morbidity.
Wide excision, a recommended treatment for osteoid osteoma, creates needless resection of surrounding bone and causes difficult intraoperative nidus identification. Less bone resection is required by successively burring through the reactive bone to identify the nidus, which is then removed with curettes and burrs. This burr-down technique requires precise preoperative anatomic localization by thin section (1-1.5 mm) computed tomography (CT) scans. In a consecutive series of 19 osteoid osteomas, 18 were accurately diagnosed before operation, using a combination of clinical findings, plain roentgenograms, and CT scans. The burr-down technique was successfully used in 15 cases, and four were treated with wide excision. There have been no local recurrences. The follow-up period for all 19 patients was at least six months. No bone grafts were required in the burr-down group in nonspinal locations; there have been no fractures despite early return to unrestricted activity. The burr-down technique was associated with less postoperative immobilization, a shorter duration of protected weight bearing, and an earlier return to activity. The burr-down technique is recommended for accessible osteoid osteoma lesions.
