Minimally invasive surgery for ablation of osteoid osteoma of the spine.

Study Design: Compare the effectiveness of two different techniques for the management of osteoid osteoma of the spine.

Objective: To describe the technique, feasibility, and indications of two different minimally invasive surgical methods for the treatment of osteoid osteoma of the spine.

Summary Of The Background Data: Current treatment of osteoid osteoma of the spine is usually conventional surgical excision.

Subsidence of stand-alone cervical cages in anterior interbody fusion: warning.

Anterior cervical decompression and fusion with anterior plating of the cervical spine is a well-accepted treatment for cervical radiculopathy. Recently, to minimise the extent of surgery, anterior interbody fusion with cages has become more common. While there are numerous reports on the primary stabilising effects of the different cervical cages, little is known about the subsidence behaviour of such cages in vivo.
