Scoliosis secondary to osteoid osteoma of the spine:differential diagnosis and management / 中国矫形外科杂志

ABSTRACT

[Objective]To evaluate diagnostic and the therapeutic options of osteoid osteoma of the spine associated with scoliosis. [Methods]Nine patients with osteoid osteoma of the spine were treated from 1997 to 2006.All patients presented with spine deformity as their main complaint at the first consultation.The mean age was 15.2 years (range 8-21 years).Two patients had their osteoid osteoma in the thoracic area,2 in the thorcolumbar area ,and 5 in the lumbar area.Three were well controlled after long term administration of nonsteroidal anti-inflammatory drugs,and the other 6 were treated with en bloc excision.[Results]All the 6 patients with en bloc excision of the tumor were pain-free post-operatively.The scoliotic curve disappeared or was less than 15 degrees in 5,but the structural curve persisted in 4.[Conclusion]The spinal osteoid osteoma should be suspected when back pain or painful scoliosis occurs in adolescents.Computed tomography is necessary to evaluate the location and features of the lesion.En bloc excision of the tumor can be suggested if the symptoms are not well relieved with nonsteroidal anti-inflammatory drugs.
