Spondylolisthesis is the forward slip of one vertebra over another. Regenerative treatments like intra-annular fibrin injection do not address the slip itself, but in selected low-grade cases where annular tears in adjacent discs are the dominant pain driver, sealing those tears can reduce pain and delay surgical fusion.
Key Takeaways
- Spondylolisthesis is graded I-V; only low-grade cases are candidates for regenerative care.
- Regenerative treatment does not stabilize the slip — it addresses adjacent disc lesions.
- High-grade or progressively unstable spondylolisthesis is a surgical case.
- Imaging plus dynamic films determine candidacy.
- An honest evaluation surfaces whether the procedure can help in a specific case.

What is spondylolisthesis?
Spondylolisthesis is a forward slip of one vertebra relative to the one below it. The slip is graded by the percentage of displacement: Grade I (under 25%), Grade II (25-50%), Grade III (50-75%), Grade IV (over 75%), and Grade V (complete dislocation). Many patients with Grade I spondylolisthesis live with the finding for years; pain comes more from associated disc lesions than from the slip itself.
When does regenerative care fit?
Regenerative care fits Grade I spondylolisthesis when imaging shows annular tears in the disc above or below the slip and pain pattern correlates with those tears. The procedure does not stabilize the slip. It addresses the disc lesion that is generating pain. For patients who have been told fusion is the next step on a Grade I slip, evaluating whether the disc lesion is the actual driver is reasonable.
When does surgery fit instead?
Surgery fits when the slip is high-grade, progressively worsening on serial imaging, or producing significant neurologic compromise. In these cases, stabilization is the right answer. The procedure is not appropriate for unstable spondylolisthesis.
How does the evaluation work?
The evaluation includes static and dynamic (flexion-extension) imaging to assess stability, pain-pattern correlation with disc lesions, and a focused neurologic exam. The Valor team gives a clear answer: candidate, non-candidate, or needs further imaging. Patients with surgical-fit anatomy are referred toward surgery, not steered into a procedure that will not help.
Clinical Note
Spondylolisthesis is one of the cases where our clinical staff most reliably refers patients toward surgery when surgery fits. A Grade III or IV slip, or a Grade I slip that is documented as progressive, is not a regenerative case. We say so plainly. The cases where the procedure can contribute are the stable Grade I slips with disc lesions — and even those require careful imaging review to confirm the disc is the dominant pain driver. The Valor team’s posture is to be specific about who can help and who cannot.
Frequently Asked Questions
Can the procedure stop the slip from getting worse?
No. Slip progression is a structural question; the procedure addresses disc lesions only.
If my slip is Grade I, am I automatically a candidate?
Not automatically. Imaging must show a disc lesion that correlates with the pain pattern.
What if I have already had a fusion for spondylolisthesis?
Adjacent-segment lesions can sometimes be addressed at discs unaffected by fusion hardware.
