Which stage of disc herniation has the highest rate of complete regression?

When a herniation becomes fully sequestered, the fragment is completely detached and free in the spinal canal. This makes it highly accessible to the body’s inflammatory and phagocytic processes. Macrophages infiltrate the area and actively resorb disc material, so the sequestered piece is more likely to disappear completely on imaging and with symptom relief over time. In contrast, an extruded fragment remains connected to the disc, so it’s less exposed to resorptive forces and may persist, and a contained protrusion is even more stable and less likely to regress entirely. Degeneration refers to chronic, diffuse disc changes rather than a discrete fragment that can be resorbed, so it doesn’t undergo complete regression in the same way. Thus, the detached, freely floating fragment in sequestration is most prone to complete regression due to the body's resorption mechanisms.
