What is spinal deformity surgery?
Corrects selected alignment problems through anterior, posterior, or combined reconstruction. Dr. Merola measures alignment across the whole spine and builds an anterior, posterior, or combined plan. Decompression, osteotomy, interbody support, implants, and fusion are selected according to the correction required.
Conditions it treats
Am I a candidate?
Adults with progressive imbalance, painful deformity, nerve compression, loss of standing tolerance, or failure of prior reconstruction may be considered after full imaging and medical optimization.
How the diagnosis and surgical level are confirmed
Adult deformity planning considers the entire standing spine rather than one painful image level. Full-length films show coronal curve, sagittal balance, pelvic relationship, and compensation through the hips and knees. MRI or CT, neurologic examination, prior fusion, frailty, bone density, nutrition, and medical risk help distinguish focal stenosis from symptoms driven by global imbalance. The plan may combine decompression, interbody support, osteotomy, fixation, graft, and anterior or posterior corridors. The correction target is individualized; making an image maximally straight is not automatically the safest functional goal. Early hospital care includes neurologic and medical monitoring, blood-loss management, walking, wound care, bowel recovery, and prevention of immobility complications. Vocational recovery starts with basic upright tolerance before driving, uneven ground, lifting, or fall exposure. A major reconstruction cannot restore normal spinal biology or guarantee pain relief. Neurologic or medical complications, nonunion, implant failure, junctional breakdown, or residual imbalance may require staged or revision care.
How Dr. Merola performs spinal deformity surgery
Dr. Merola measures alignment across the whole spine and builds an anterior, posterior, or combined plan. Decompression, osteotomy, interbody support, implants, and fusion are selected according to the correction required.
Recovery timeline and returning to work
Recovery is longer than for a focal decompression and includes hospital care, staged walking, rehabilitation, medical optimization, and gradual return to work based on healing and function.
Alternatives and related procedures
Smaller decompression or limited fusion may be sufficient when symptoms come from one level. Larger reconstruction is reserved for deformity that drives pain, imbalance, or neurologic compromise.
Spinal Deformity Surgery risks and outcomes
Risks include infection, blood loss, neurologic injury, medical complications, nonunion, implant failure, junctional problems, incomplete correction, and additional surgery.

Two words come up in every deformity consultation: coronal and sagittal. Coronal is the sideways curve you see in the mirror. Sagittal is the front-to-back stack, head over ribs over pelvis, and it is the one that decides how you feel.
A spine that leans forward burns muscle standing still. Patients describe it as walking into wind. Restoring sagittal balance, the stack, is what realignment surgery is for. The sideways curve gets corrected along the way, but the energy economics of your posture is the prize.
That is also why the planning films are taken standing, why flexibility films follow, and why two patients with similar-looking curves can leave with entirely different plans.
The evaluation takes its time, on purpose
Deformity work earns the most deliberate evaluation in the specialty. Standing alignment films. Flexibility films. Nerve studies when legs are involved. Bone density, because hardware in soft bone is a plan built on sand. Health screening, because these operations are marathons.
Then the conversation, with the films up, tracing the plan level by level: what gets corrected, what gets fused, what gets left alone, what the recovery demands, and what it cannot deliver. Adults make good decisions with that much information. Start it with a consultation.
When the answer is not surgery
More deformity consultations end in a plan without an operation than most patients expect, and that is a feature of a practice that does the operations well: the recommendation against is credible.
Conservative deformity care is real work. Therapy aimed at the curve's specific demands, sagittal-plane conditioning, weight strategy where it changes the balance math, injections aimed at a diagnosed pain generator rather than the whole back, and bone-health management to keep the architecture from worsening. Standing films on a schedule watch for progression quietly.
The discipline is in the follow-up. A watched curve is re-measured; a treated pain generator is re-examined; and when the conservative plan stops holding the line, the operative conversation starts from evidence, not fatigue. Either way, you are not waiting alone with a big diagnosis and no plan.
Why adults wait, and when waiting is right
Adults with deformity usually arrive years after the curve first announced itself, and the first consultation often spends as much time on why they waited as on what to do.
The reasons are sound. The demands of a working life, the fear that surgery is the only offering, and the fact that many curves stay quiet for years. Surgery is not the default destination of a scoliosis diagnosis in adulthood, and a practice that operates on every curve it measures is not one to trust.
The waiting that is right is attended waiting: films on a schedule, function tracked honestly, conservative care given a real trial. The waiting that is wrong is silent, the kind where balance erodes and endurance quietly shrinks until the operation is bigger than it needed to be. The difference between the two is whether anyone is watching, and this practice watches.
Week in and week out, this is the kind of case that walks through the door in Park Slope.
If your pain follows one of the patterns described above, the next step is a proper examination. Contact the office and it gets scheduled.
Frequently Asked Questions
How do I know whether I need spinal deformity surgery?
Adults with progressive imbalance, painful deformity, nerve compression, loss of standing tolerance, or failure of prior reconstruction may be considered after full imaging and medical optimization. The decision follows a direct examination and review of imaging, symptoms, prior care, health, and functional limits.
What happens during spinal deformity surgery?
Dr. Merola measures alignment across the whole spine and builds an anterior, posterior, or combined plan. Decompression, osteotomy, interbody support, implants, and fusion are selected according to the correction required. The exact levels and approach are individualized, and Dr. Merola performs the operation personally.
How long is recovery after spinal deformity surgery?
Recovery is longer than for a focal decompression and includes hospital care, staged walking, rehabilitation, medical optimization, and gradual return to work based on healing and function. Timing still varies with the approach, levels treated, healing, neurologic findings, and job demands.
What are the alternatives to spinal deformity surgery?
Smaller decompression or limited fusion may be sufficient when symptoms come from one level. Larger reconstruction is reserved for deformity that drives pain, imbalance, or neurologic compromise. Non-surgical care may remain reasonable when the examination and imaging support it.
What risks should I understand before spinal deformity surgery?
Risks include infection, blood loss, neurologic injury, medical complications, nonunion, implant failure, junctional problems, incomplete correction, and additional surgery. Symptoms may improve incompletely, and additional care or surgery may be needed. No result is guaranteed.
What are the treatment options for spinal deformities?
The full range: observation, conditioned physical therapy, injections for pain generators, and realignment surgery when the deformity progresses or the imbalance is disabling. Adults with deformity get a deliberately unhurried evaluation, because the wrong operation is worse than a later one.
What is the most complex spine surgery?
Revision and deformity reconstruction sit at the demanding end of the specialty: multiple levels, corrected alignment, compromised anatomy from prior operations. It is a specific skill set, and it is a focus of Dr. Merola's practice.
