Biomechanical effects of partial and full L4-L5 disc nucleotomy: a coupled musculoskeletal finite element modeling study
The unintended increase in post-nucleotomy disc bulging may impinge on nearby nerve roots, offering a biomechanical rationale for pain recurrence. Current findings underscore the biomechanical risks of disc depressurization and reinforce the clinical importance of nucleus-sparing and annulus-sealing techniques in nucleotomy planning.
