How to interpret computed tomography of the lumbar spine

Z Ahmad et al. Ann R Coll Surg Engl. 2014 Oct.

Abstract

Computed tomography (CT) of the spine has remained an important tool in the investigation of spinal pathology. This article helps to explain the basics of CT of the lumbar spine to allow the clinician better use of this diagnostic tool.

Chance fracture: This occurs in the upper lumbar spine, usually owing to lap belt injury, and is common in children. It consists of a compression injury to the anterior portion of the vertebral body and a transverse fracture through the posterior elements of the vertebra and posterior portion of the vertebral body. The pedicles can split in two.
