Interlaminar endoscopic decompression approaches the spine from the back through the space between adjacent lamina. It's particularly well-suited to central canal stenosis, central disc herniations, and decompressions where posterior access provides the clearest path to the target. Incision less than ⅓ inch, outpatient, same-day discharge.
Where the interlaminar window is
Between adjacent vertebrae, viewed from behind, there’s a window between the lamina of one level and the lamina of the next. The window is bounded by bone above and below and by the facet joints on each side. Through this window, an endoscope can access the central canal, lateral recess, and certain disc locations.The approach is the posterior equivalent of what transforaminal accomplishes through the foramen. Each approach has its preferred anatomical targets.
Best-fit pathology
Central canal stenosis at lumbar levels — decompression of the lamina, ligamentum flavum, and medial facet often addressable through the interlaminar window. Central or near-central disc herniations — the interlaminar approach often gives the most direct access. Lateral recess stenosis — accessible through the interlaminar window with technique modification.Foraminal herniations and far-lateral pathology are usually better served by the transforaminal approach. The choice depends on anatomy.
Anesthesia
Most interlaminar procedures are performed under local anesthesia at the surgical site plus light sedation; some are performed under general anesthesia depending on patient factors and surgeon preference. The procedure typically takes about an hour.Continuous saline irrigation maintains visibility through the working channel. Bipolar coagulation handles small bleeding. Magnified video provides the surgeon with detailed visualization of the working area.

How a typical patient pathway unfolds
Most patients arrive at Synergy having already seen one or more surgeons elsewhere. The pathway here is built around that reality: a careful second read of the existing imaging, a candid conversation about what is and is not warranted, and — when intervention does make sense — a procedure that is as small as the pathology allows.
The starting point is usually the free MRI review. You upload or mail your existing scan; Dr. McMillan reviews it personally and responds with a candid assessment. If the review suggests you are a candidate for the endoscopic approach, the next step is a $250 consultation (credited toward the procedure if you proceed) to discuss the specifics for your anatomy. If the review suggests you are not a candidate, the response tells you that directly and offers honest guidance about what might serve better.
For patients who decide to move forward, scheduling typically happens within two to three weeks depending on the calendar. The procedure itself is outpatient — most patients arrive in the morning, go home the same day, and are walking with a small dressing covering the incision. Routine follow-up visits over the recovery window are part of the procedure bundle, and the office coordinates with your local providers as needed. Out-of-town patients are accommodated as a routine matter; we see patients from across South Carolina, Georgia, North Carolina, Tennessee, and beyond.
Recovery
Same-day discharge typical. Patients walk within hours and go home with simple wound care for the small incision. Pain relief — when the procedure addressed the right pathology — often develops over days as the previously compressed neural structures recover.Recovery comparison to traditional open laminectomy is favorable, particularly in terms of soft-tissue disruption and post-operative recovery time.
Bottom line
Interlaminar endoscopic decompression approaches the spine from the back through the space between adjacent lamina. It's particularly well-suited to central canal stenosis, central disc herniations, and decompressions where posterior access provides the clearest path to the target. Incision less than ⅓ inch, outpatient, same-day discharge.
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 interlaminar endoscopic decompression, 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 interlaminar endoscopic decompression
At Synergy Spine Center, interlaminar endoscopic decompression 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 lumbar spinal stenosis or central canal stenosis 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 interlaminar endoscopic decompression 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 interlaminar endoscopic decompression 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 PubMed — Interlaminar Endoscopic Decompression for patients who want to read more about the underlying evidence.
Frequently asked
When is interlaminar preferred over transforaminal?
Central canal pathology, central disc herniations, and certain lateral recess decompressions. The choice depends on what specifically needs to be reached. 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.
Is this the same as endoscopic discectomy?
Interlaminar endoscopic decompression can be a form of endoscopic discectomy when the target is a disc fragment. It’s also used for stenosis decompression — the same approach, different target. 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.
How long is the procedure?
Typically about an hour. Complex multilevel cases may take longer. Transparent bundled pricing for interlaminar endoscopic decompression is published openly at /spine-surgery-cost-transparent-pricing/, so you can plan financially before scheduling and avoid surprise bills.
What's the incision size?
Less than ⅓ inch. The procedure works through a small portal under continuous saline irrigation. To find out whether you’re a candidate for interlaminar endoscopic decompression, submit your imaging through the free MRI review — Dr. McMillan reviews each scan personally and provides candid candidacy assessment within several business days.
Can multiple levels be done in one session?
Yes for appropriate cases, with longer procedure time. Each level adds time and complexity. To find out whether you’re a candidate for interlaminar endoscopic decompression, submit your imaging through the free MRI review — Dr. McMillan reviews each scan personally and provides candid candidacy assessment within several business days.
Will I have a scar?
A small scar at the incision site, typically heals to be barely visible over months. 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.
