Spinal cord stimulation (SCS) is an implanted device that delivers electrical signals to the spinal cord, altering pain perception. Evaluation involves a trial period with externalized leads to confirm response before permanent implantation. SCS has a specific role in post-surgical pain syndromes and certain chronic radicular pain not responding to other treatments.
How spinal cord stimulation works
Electrical leads positioned in the epidural space (between the cord and the bony canal) deliver low-current signals that modulate how pain is perceived. The mechanism isn’t fully understood — likely a combination of effects on pain signal transmission and central processing.For appropriate patients, the result is meaningful pain reduction without addressing the underlying mechanical pathology. This makes SCS particularly relevant for pain syndromes where there isn’t a clearly addressable mechanical source — post-surgical pain after appropriate procedures, persistent radicular pain after decompression.
The trial period
Before permanent implantation, patients undergo a trial period — typically 5-7 days — with externalized leads delivering the same stimulation that a permanent device would. The trial answers the essential question: does this particular patient experience meaningful pain reduction from SCS?If the trial produces significant relief, permanent implantation is reasonable. If not, the trial leads are removed and SCS is ruled out for this patient. The trial saves patients from the cost and time of permanent implantation when the technology won’t help them.
Best-fit patients
Failed back surgery syndrome with persistent radicular pain — the classic indication. Complex regional pain syndrome. Some forms of refractory chronic pain syndromes. The common thread: pain not adequately addressed by anatomical interventions and not responding to standard non-surgical treatments.Not a first-line option. Generally considered after appropriate workup, conservative care, targeted interventions, and sometimes spine surgery haven’t produced adequate results. Patient selection is critical — wrong indications produce poor outcomes.
Send your MRI for a free review
Dr. McMillan reviews each scan personally. You get a candid answer about candidacy before any travel or scheduling.
What the consultation actually looks like
The initial visit with Dr. McMillan focuses on what your imaging actually shows and what your symptoms are telling us — independent of what you’ve been told previously. The $250 consultation fee covers his time to review your MRI personally and give you a candid evaluation. Most patients leave the visit with a clear answer: either you’re a candidate for the endoscopic approach (and we discuss what that would involve in your specific case), or you’re not (and we tell you why, and what we would suggest instead). No high-pressure scheduling, no surprise add-ons.
For patients traveling from outside the Upstate, the consultation can usually be coordinated with the procedure to minimize travel. A typical out-of-town pathway is: send your MRI for the free review, have a phone or video conversation with Dr. McMillan after his review, and travel for a single combined visit-and-procedure schedule when you decide to move forward. The office handles the logistics — lodging recommendations, transportation guidance, and post-op coordination with your local primary care physician.
If you have been told you need a fusion and you are not sure, or if you have been managing this with conservative care that has stopped working, the next step is the free MRI review. There is no obligation and no cost to send your scan. Dr. McMillan reviews each one personally. The response will tell you plainly whether the endoscopic approach fits your specific anatomy, or whether your situation calls for a different plan.
What evaluation involves
Comprehensive pain medicine consultation, psychological assessment (standard practice — confirms the patient is a good candidate for the trial and likely permanent implantation), confirmation of appropriate prior treatments, and discussion of the trial process and expected outcomes.The evaluation isn’t just about whether SCS is technically appropriate; it’s about whether this is the right intervention for this patient at this point in their care. Honest conversation about expected benefits and realistic outcomes is essential.
Bottom line
Spinal cord stimulation (SCS) is an implanted device that delivers electrical signals to the spinal cord, altering pain perception. Evaluation involves a trial period with externalized leads to confirm response before permanent implantation. SCS has a specific role in post-surgical pain syndromes and certain chronic radicular pain not responding to other treatments.
If you’ve been told you need a fusion — or you’re trying to avoid one — a free MRI review is the most useful next step. Dr. McMillan reviews each scan personally and tells you candidly whether the endoscopic approach fits your specific anatomy.
For patients dealing with spinal cord stimulation evaluation, the conversation comes down to specifics: what your imaging actually shows, what your symptoms are actually telling us, and which procedure (if any) genuinely matches that pattern. The candid answer is sometimes that you do not need surgery yet; the candid answer is sometimes that you do, but a smaller operation than the one you have been quoted. A second-opinion MRI review separates those cases and gives you the information you need to make the decision well.
The Synergy approach to spinal cord stimulation evaluation
At Synergy Spine Center, spinal cord stimulation evaluation is performed by Dr. Marion McMillan personally — the same surgeon who reviews your imaging, plans the operation, and handles your post-operative care. This single-surgeon model isn’t unusual for boutique surgical practices; it’s structural at Synergy because the spine literature shows volume-outcome relationships for individual operators. Patients pursuing this procedure most often arrive with a diagnosis of failed back surgery syndrome or post-laminectomy syndrome after being told elsewhere that more invasive surgery — typically fusion — is their only path forward.
Candidacy is established before any travel commitment through the free MRI review process. Patients submit recent imaging and a brief clinical history; the review identifies whether the specific pathology shown on imaging would respond to spinal cord stimulation evaluation or whether a different intervention would be more appropriate. If you’re a candidate, you’ll receive a written assessment along with transparent bundled pricing for the procedure. If you’re not a candidate, you’ll be told that directly, often with a referral to the appropriate specialty — the review is screening, not sales.
Recovery from spinal cord stimulation evaluation is intentionally faster than from traditional open spine surgery or fusion. Most patients return to office work within one to two weeks; manual labor takes four to six weeks. Routine post-operative follow-up is included in the bundled price, and for out-of-town patients much of the follow-up happens remotely through phone or secure video — the 3-day plan documents typical visit cadence. Authoritative clinical background on this procedure is also available at Cleveland Clinic — Spinal Cord Stimulator for patients who want to read more about the underlying evidence.
Frequently asked
Is SCS a surgery?
Implantation is a surgical procedure, though typically less involved than spine surgery. Lead placement is image-guided; the pulse generator is implanted subcutaneously. To find out whether you’re a candidate for spinal cord stimulation evaluation, submit your imaging through the free MRI review — Dr. McMillan reviews each scan personally and provides candid candidacy assessment within several business days.
How long does the trial take?
Typically 5-7 days with externalized leads. During the trial, the patient experiences the stimulation in daily life and reports the response. Transparent bundled pricing for spinal cord stimulation evaluation is published openly at /spine-surgery-cost-transparent-pricing/, so you can plan financially before scheduling and avoid surprise bills.
Will insurance cover SCS?
For appropriate indications with appropriate workup, generally yes. Specific coverage requirements vary. Patients who travel for care typically combine consultation and procedure into a single trip — the 3-day plan documents the standard cadence and lodging logistics for out-of-town patients.
Can the device be removed if it doesn't work?
Yes — both trial leads and permanent implants can be removed. This is part of why the trial period is essential. To find out whether you’re a candidate for spinal cord stimulation evaluation, submit your imaging through the free MRI review — Dr. McMillan reviews each scan personally and provides candid candidacy assessment within several business days.
Is SCS appropriate as a first-line treatment?
Generally no. SCS is considered after appropriate prior treatments haven’t produced adequate results. To find out whether you’re a candidate for spinal cord stimulation evaluation, submit your imaging through the free MRI review — Dr. McMillan reviews each scan personally and provides candid candidacy assessment within several business days.
How long does an implanted device last?
Pulse generators have battery lives measured in years, typically requiring replacement at intervals. Newer devices use rechargeable batteries with longer effective lifespan. For background on the most common diagnosis treated with this procedure, see the failed back surgery syndrome page, which covers symptoms, diagnostic workup, and treatment options in detail.
