Can a sequestrated fragment migrate?

Can a sequestrated fragment migrate?

• A. No
• B. Only Superiorly
• C. Only Medially
• D. Yes, superiorly, inferiorly, medially, or laterally

Answer: (D)

A sequestrated disc fragment becomes a free body in the epidural space because it has detached from the parent disc and is no longer anchored. With no strong attachments, it can move under gravity, CSF dynamics, and the anatomy of the epidural space. This allows the fragment to migrate in several directions, not just one. It can move upward (superiorly), downward (inferiorly), toward the middle (medially) toward the thecal sac, or toward the sides (laterally) toward the neural foramen. So it’s possible for a sequestrated fragment to migrate in any of these directions, making the option describing migration in multiple directions the correct one.
