Nomenclature and Classification of Lumbar Disc Pathology
The Proper Terminology for Reporting Lumbar Intervertebral Disk Disorders

The Nomenclature and Classification of Lumbar Disc Pathology developed from a need for reliable terms that describe normal and pathologic conditions of lumbar discs in ways that can be interpreted accurately, consistently, and with reasonable precision among physicians. A multi-disciplinary task force from the North American Spine Society (NASS) addressed deficiencies in standardization and current practice, and made detailed recommendations for standardization in 1995. This work was published in 1997 by NASS and the American Academy of Orthopaedic Surgeons (AAOS).* Although comprehensive, this document remained deficient in clarifying some controversial topics. To address the remaining needs, and in the hope of securing endorsement sufficient to result in universal standardization, a joint task force was formed by NASS, the American Society of Neuroradiology (ASNR), and the American Society of Spine Radiology (ASSR). This work is the product of those task forces.
