Classification of Disc Disorders
The following disc disorder classifications and their descriptions are derived form the nomenclature and classification of lumbar disc pathology, recommendations of the combined task forces of the North American Spine Society, American Society of Spine Radiology and American Society of Neuroradiology.
Normal disc: This term is used to describe a young intervertebral disc that is structurally normal. A symmetric disc bulge which involves between 50 and 100% of the circumference of the disc is not considered a form of herniation and is more likely to represent a normal state.
Disc with Congenital/Development Variation: This classification includes those discs, which are structurally abnormal as the result of hereditary considerations. This includes disc that undergo structural (morphological) changes due to adaptation to abnormal growth of the spine.
Degenerative/Traumatic Disc Lesion: This is a broad category which includes discs that present with degenerative changes, evidence of traumatic compromise or a combination of both. This category includes degenerative changes that may be age-related.
