Postlaminectomy Syndrome with Predominantly Radicular Leg Pain: What to Do After Percutaneous Epidural Adhesiolysis Has Failed

This protocol targets patients with postlaminectomy syndrome whose pain is predominantly radicular and neuropathic in the lower limbs — with no predominant axial nociceptive component — and who have not achieved adequate pain relief following percutaneous epidural adhesiolysis.

Clinical Scenario
Pain is predominantly radicular and neuropathic, localised to the lower limbs. Predominantly axial nociceptive pain is absent. Distinguishing whether pain is primarily axial or radicular is essential for selecting the appropriate intervention pathway in postlaminectomy syndrome.
Previous Treatment — Failure Condition
The prior intervention — percutaneous epidural adhesiolysis using epidural injection of hyaluronidase with saline and steroids — did not achieve the intended goals of chronic back and radicular leg pain reduction. This protocol defines the structured next step after that failure.
Next-Line Approach (partial)
For patients with radicular neuropathic pain who have not responded to prior interventions, a spinal cord stimulation approach is strongly indicated — involving a formal trial phase before any further step. The complete selection criteria, trial protocol, and subsequent pathway are detailed in the full structured regimen.
Treatment Goals
Reduction of chronic back and leg pain — improved physical function — improved sleep quality.

When deciding on which procedures may be efficacious in FBSS patients, it is useful to determine if the pain is predominantly axial or radicular.

For those patients with predominantly radicular pain, epidural injection of steroids under fluoroscopic guidance may be achieved through several routes.

A trial of spinal cord stimulation (SCS) is to be strongly considered in all patients with radicular pain who have failed the more conservative measures.

The patient selected for SCS implantation should have a stimulation trial and only if this is successful, permanent surgical implantation of a spinal stimulator should be performed.

SCS is generally accepted to improve chronic back and leg pain (CBLP), physical function, and sleep quality.

SCS as a treatment option for adults with chronic pain of neuropathic origin who: continue to experience chronic pain (measuring at least 50 mm on a 0-100 mm Visual Analog Scale) for at least 6 months despite appropriate conventional medical management, and who have had a successful trial of stimulation as part of the assessment.
