Sciatica Is Not a Surgery-First Problem: Mark Croucher on Diagnosis and Collaborative Spine Care

Most patients who walk into Dr. Mark Croucher's office with shooting leg pain have already done the rounds. They've been told to rest; they've been handed a muscle relaxer and sent home; they've been shown an MRI report full of words — annular fissure, foraminal narrowing, facet arthropathy — without a clear explanation of which finding actually matters. Many have spent months cycling between brief relief and flare-ups, and a smaller but anxious subset have already been told to consider surgery. What they need, and rarely get up front, is a careful answer to a deceptively simple question: what is actually causing this pain, and what should we do first?

That question is the center of gravity at The Spine Center Of Williamsburg in Williamsburg, Virginia, where Dr. Mark Croucher, DC, practices as an orthopedic chiropractor. His clinical focus is the spine — particularly lumbar radiculopathy, spinal stenosis, and painful degenerative disc disease — and his approach is built around accurate diagnosis, evidence-based conservative care, and close collaboration with neurosurgeons, pain specialists, and orthopedic physicians. In a field where sciatica is often treated as a single diagnosis with a single playbook, Croucher treats it as what it actually is: a symptom with several possible causes, each pointing toward a different treatment path.

Sciatica Is a Symptom, Not a Diagnosis — and Why That Matters

The word sciatica gets used so casually that patients often arrive believing it's a diagnosis in itself. Clinically, it isn't. Sciatica describes a pattern of pain — typically radiating from the low back or buttock down the leg along the distribution of the sciatic nerve or a lumbar nerve root — but the pathology behind that pattern varies considerably. A lumbar disc herniation compressing the L5 or S1 nerve root produces one presentation; central or foraminal stenosis in an older patient produces another; hip pathology, sacroiliac dysfunction, or piriformis involvement can convincingly mimic both. Treatment that works beautifully for one of these can be useless — or worse — for another. That is why Croucher opens every new case the same way: with a careful history, a hands-on orthopedic and neurologic examination, and imaging review only in context.

This insistence on a granular diagnosis isn't academic — it shapes everything that follows. A patient whose leg pain worsens with prolonged standing and eases when they lean forward over a grocery cart is telling a very different story than one whose pain spikes with sitting and coughing. The first pattern suggests neurogenic claudication from stenosis; the second is far more consistent with a disc-related radiculopathy. Croucher's examination adds layers of confirmation — straight-leg raise, slump test, dermatomal sensory mapping, reflex asymmetry, motor grading — before any treatment plan is finalized. Imaging, when it's indicated, is read alongside the clinical picture rather than in place of it, because asymptomatic disc bulges and degenerative findings are extremely common and rarely tell the whole story on their own.

That diagnostic rigor also protects against a quiet but important failure mode in sciatica care: treating the wrong pain generator. Published reviews consistently emphasize that identifying the specific cause of radicular pain is a prerequisite for choosing effective treatment, and that conservative care pathways should be matched to the underlying pathology rather than applied as a uniform protocol.^[1] For patients who've already tried a one-size-fits-all approach without result, the experience of a thorough exam — where someone actually connects the dots between their symptoms, their exam findings, and their imaging — is often the first time the problem starts to feel solvable.

The 90% Number: Why Manual and Exercise Therapy Come First

One of the most important things Croucher tells new patients is also one of the most reassuring: the large majority of people with sciatica improve without surgery. That framing isn't optimism — it's the consensus of decades of clinical research. Large comparative trials of lumbar disc herniation with radiculopathy have found that while early surgery can deliver faster pain relief in selected patients, functional and pain outcomes at one and two years are broadly similar between surgical and well-delivered conservative pathways.^[2] The practical implication is that most patients have the time — and the statistical tailwind — to give conservative care a fair trial before considering an operation.

For Croucher, a fair trial means two things done well: manual therapy tailored to the patient's specific pathology, and active exercise therapy built around graded loading, mobility, and nerve glides. Spinal manipulation and mobilization are not applied indiscriminately; they're used where the examination and history support them, with technique selection guided by the involved level and the patient's tolerance. Exercise is layered in early rather than held back until pain is gone, because motion and progressive load are themselves part of how the nervous system recalibrates.

The evidence base for this first-line strategy has strengthened considerably in the last fifteen years. A randomized controlled trial in The American Journal of Medicine found that spinal manipulation produced clinically meaningful improvements in pain and disability for patients with subacute and chronic lumbar radiculopathy compared with sham intervention.^[3] In a now widely cited study, patients with sciatica from confirmed disc herniation who had failed at least three months of prior nonoperative care were randomized to either microdiskectomy or standardized chiropractic spinal manipulation — and roughly 60% of the manipulation group improved to a degree comparable with their surgical counterparts, with the remainder still able to go on to surgery with excellent outcomes.^[4] For a population often told their next step is the operating room, that is a striking result.

Exercise therapy does similar work from a different angle. A systematic review and meta-analysis in Spine comparing advice to stay active against supervised structured exercise in sciatica concluded that both approaches reduce pain and disability, reinforcing the core principle that movement — not rest — is the right default.^[5] Croucher tends to blend the two: clear guidance on keeping the day moving, combined with a short, specific set of prescribed exercises the patient can actually complete. Patients curious about how manual and movement-based care fit together often find helpful context in holistic.health's overview of the best practitioners for back and neck pain, which maps the conservative landscape many people only discover after months of trial and error.

Collaborative Care: Who You Want in the Room With You

The second half of Croucher's approach is a recognition that not every case is a chiropractic case — and that the right answer for a complicated spine is almost never a single practitioner working in isolation. Spinal stenosis with progressive neurologic findings, a large extruded disc fragment with worsening motor weakness, a cauda equina red flag, or pain that isn't responding to well-executed conservative care all require input from surgical and interventional colleagues. The practitioners who serve patients best, in his view, are the ones who know their own scope of practice precisely and have built real professional relationships with the specialists on either side of it.

At The Spine Center Of Williamsburg, that collaboration is operational rather than cosmetic. Imaging gets reviewed with the specialists who would be performing any procedure; epidural steroid injections or selective nerve root blocks are coordinated with pain management when conservative care alone isn't enough; and if surgery is eventually the right call, the handoff is clean and informed rather than a patient being passed between unfamiliar offices. The published literature backs this model directly — a Cochrane systematic review and BMJ meta-analysis found that multidisciplinary biopsychosocial rehabilitation produced more durable improvements in pain and disability for chronic low back pain than standard physical treatment or usual care, with benefits sustained over the long term.^[6] Spine problems are inherently multifactorial; care that reflects that tends to outperform care that doesn't.

Collaborative care also changes the emotional calculus for patients. Someone who has been bouncing between providers with conflicting opinions often arrives exhausted and frightened. A single practitioner who can say, credibly, “Here's what I think is going on, here's what I'd like to try first, and here's exactly who we'd involve if we need to escalate” changes the conversation. Patients who want to understand the broader conservative toolkit — including non-chiropractic modalities that can complement manual care — often benefit from reading about acupuncture for chronic low back pain as part of a layered approach. The point is not that one tool is right for everyone; it's that a well-networked clinician can match the tool to the patient instead of the other way around.

That network also determines who gets escalated quickly. Progressive weakness, saddle anesthesia, bowel or bladder changes, severe and rapidly worsening pain unresponsive to positional change — these aren't cases for extended conservative trials, and Croucher is explicit about that with patients. The goal of first-line conservative care is to help the majority who will respond to it; the goal of tight specialist relationships is to make sure the minority who need more get it without delay.

For patients whose lives have been narrowed by months of pain, the downstream effects of a coherent plan can be unexpectedly broad. Persistent pain is cognitively and emotionally taxing, and patients sometimes notice improvements in sleep, mood, and focus as their sciatica settles — an experience that parallels research on how sustained inflammation and pain states can affect cognition, discussed in holistic.health's piece on chronic inflammation and brain fog. It's a reminder that treating the spine well is rarely just about the spine.

The Takeaway

Croucher's approach is easy to summarize but harder to execute: take the time to diagnose the actual pain generator; lead with the treatments the evidence supports as first-line; and surround the patient with a real team of specialists, not a rolodex of referrals. Each of those steps sounds straightforward in isolation. Together, they're what separate a practice that helps most of its sciatica patients avoid surgery from one that simply waits for them to get worse.

For patients in and around Williamsburg who have been living with leg pain they've been told to “just rest” through — or who have been handed a surgical consultation without a clear non-surgical plan alongside it — the framing Dr. Croucher offers is quietly radical in its ordinariness. Most sciatica is not a surgical problem. It is a diagnostic problem, a treatment-matching problem, and a coordination problem. Solve those, and the leg pain usually takes care of itself.
