Planning a management strategy for spinal osteoblastomas and osteoid osteomas may become possible through the use of modern imaging. It is still difficult to completely resect the lesion intraoperatively though, say German researchers.
Orthopaedic surgeons at Westfalische Wihelms-University, in Munster, and Klinikum Neustadt, in Neustadt treated 22 patients for these relatively rare bone-forming tumours, between 1980 and 1999.
Nine patients had osteoid osteoma, and 13 osteoblastoma; the locations of the tumours varied. Four were located in the cervical spine, six in the thoracic spine, 10 in the lumbar spine and two in the sacrum. Between the onset of pain and surgical intervention the duration averaged 16.6 months in the 12 patients who were treated in 1980, and 10 who underwent treatment in the 1990's.
