Sequestrated disc, also referred to as a free disc fragment, corresponds to extruded disc material that has no continuity with the parent disc and is displaced away from the site of extrusion. By definition, it corresponds to a subtype of disc extrusion.

The term "migrated" disc refers only to position and not to the continuity of disc substance. So, this term can be used when referring either to extruded discs that still have continuity or those without, i.e. sequestrated (e.g. disc extrusion migrated caudally, sequestrated disc migrated cranially).
