Overview
Failed back surgery syndrome (FBSS) refers to chronic back or leg pain that persists or recurs after lumbar spine surgery — including discectomy, laminectomy, spinal fusion, or other procedures. It is estimated to affect 10–40% of patients who undergo lumbar spine surgery and represents one of the most challenging and underserved populations in pain medicine. Despite its name, FBSS does not imply any error in surgical technique; rather, it reflects the complexity of spinal pain and the limitations of surgery as a pain treatment. Dr. Migdale specializes in the interventional management of FBSS, where her dual training in neuromodulation and musculoskeletal medicine is particularly valuable.
Why Does Pain Persist After Back Surgery?
Back surgery can fail to relieve pain for multiple reasons: the surgery may have addressed the structural problem but the nervous system had already become sensitized (central sensitization); scar tissue (epidural fibrosis) can form around nerve roots after surgery; adjacent disc levels may develop new pathology following fusion; and in some cases, the original pain generator may not have been correctly identified before surgery.
Why Spinal Cord Stimulation Is the Gold Standard for FBSS
Multiple high-quality clinical trials have demonstrated that spinal cord stimulation outperforms repeat surgery and continued opioid therapy for FBSS. SCS works by delivering mild electrical pulses to the spinal cord that modulate pain signals before they reach the brain. Modern SCS systems offer advanced waveforms — including high-frequency and burst stimulation — that provide effective relief without the paresthesia (tingling sensation) of older systems.
Other Options
Beyond SCS, Dr. Migdale evaluates FBSS patients for other contributing factors that may be amenable to targeted treatment: facet joint pain (medial branch blocks, radiofrequency ablation); epidural adhesions (epidural lysis of adhesions, where appropriate); sacroiliac joint dysfunction; myofascial components (trigger point injections, manual therapy); and medication optimization. A thorough evaluation is essential before recommending any specific intervention.
