Which of the following is NOT a listed stage in the typical progression of a disc herniation?

The progression of a disc herniation reflects changes in the disc itself as it degenerates and the nucleus pulposus escapes through the annulus fibrosus. Degeneration is the initial weakening and dehydration of the disc that sets the stage for herniation. Prolapse (protrusion) occurs when the nucleus begins to bulge into the weakened annulus but remains within the disc and still connected to the center. Extrusion is a more advanced step where the nucleus pushes through the annulus and the posterior longitudinal ligament, extending beyond the disc space and potentially becoming a free fragment. Dysplasia is not part of this sequence; it denotes abnormal development of tissue or bone rather than a stage of disc herniation. So dysplasia is not a listed stage in the typical progression.
