Selective en bloc resection of osteoid osteoma of the superior articular process of the sacral spine. A case report.

Abstract

Selective en bloc resection of an osteoid osteoma from the superior articular process of the sacral spine was performed, sparing the facet joint. Computed tomography was very useful, both in making a diagnosis and in facilitating precise planning of the operative procedure. The paraspinal approach readily facilitated complete excision of the tumoral nidus with minimal surgical dissection.
