Herniation disk types, used for MRI exams
Bulge–circumferential symmetric extension of the disk beyond interspace
Protrusion–focal or asymmetric extension of the disk beyond interspace
Extrusion–more extreme extension of the disk beyond interspace Note: Bulges and protrusions on MRI examination are common findings in normal subjects, and appear to be coincidental findings–NEJM 1994; 331:69oa
