Post-laminectomy syndrome (PLS) describes persistent pain after lumbar laminectomy. The drivers are often residual annular tears, adjacent-level disc problems, or scar tissue. Regenerative care can address annular tears without revision surgery, with about 80% of failed-surgery patients reporting positive outcomes.
Key Takeaways
- PLS is a form of Failed Back Surgery Syndrome.
- Annular tears often remain after disc fragment removal.
- About 80% of failed-surgery patients reported positive outcomes after the regenerative procedure.
- Revision surgery typically has lower success than the first.
- Evaluation determines whether revision is necessary.
What Is Post-Laminectomy Syndrome?
Persistent or recurrent pain after laminectomy that does not resolve with standard postoperative care. It is not a single condition — it is an umbrella term for several possible drivers.
Why Does PLS Happen?
- The annular tear remained open after disc material was removed.
- A new herniation occurred at the same level.
- An adjacent disc became symptomatic.
- Scar tissue produced new nerve irritation.
- The original pain generator was not the structure that was removed.
What Are the Treatment Options?
- Continued conservative care.
- Image-guided injections.
- Spinal cord stimulation for neuropathic pain.
- Intra-annular fibrin injection for annular tears.
- Revision surgery when indications support it.
How Does Regenerative Care Help?
Sealing the annular tear with an FDA-approved fibrin sealant stabilizes the disc so it can heal naturally. Reported 80% positive outcomes among patients with prior failed surgery.
Clinical Note
PLS patients often arrive at Valor convinced revision is their only option. In a meaningful share of cases, an annular tear is the actual problem, and it does not require fusion or further open surgery.
How to Approach the Decision
- Get a current MRI and prior surgical report.
- Have a physician confirm what is generating pain.
- Rule out instability or new structural problems.
- If an annular tear is the cause, evaluate regenerative care before revision.
