The use of the transpillar posterolateral approach to resect cervical osteoid osteomas: operative technique and results

Osteoid osteomas located in the cervical spine are a rare cause of cervical and shoulder pain. However, successful diagnosis of these tumors has become more frequent in the recent years. This is due to more available diagnostic modalities as well as to physician awareness of the possibility that such lesions can cause cervical pain syndrome. Resection of osteoid osteomas located close to the vertebral artery is often technically difficult, and poses significant risk to the patient. We describe resection of such tumors using a posterolateral transpillar approach in three patients. The advantage of this approach is the direct and relatively easy visualization of the tumor, without the need for an extensive dissection. The stability of the cervical spine is not compromised by this approach. However, extension of the operative field is difficult, should the need arise.
