title: Fixation techniques and instrumentation used in the thoracic, lumbar, and lumbosacral spine.
abstract: The radiologist is faced with continual changes in both surgical techniques and instrumentation for the spine. To properly evaluate radiographic and special imaging studies, it is necessary to have a working knowledge of the devices used and the principles that direct their use. This article discusses the identification and function of the most common instrumentation in the thoracic, lumbar, and lumbosacral spine.
