Can Scoliosis Cause Sciatica? Charlotte NC | Foraminal Stenosis and Leg Pain | Clear Life Scoliosis

By Dr. Justin Dick, DC · Clear Life Scoliosis and Chiropractic Center, Charlotte, NC · Published October 26, 2026

Yes. In adults with lumbar scoliosis, sciatica usually comes from narrowing of the openings where nerve roots exit the spine (foraminal stenosis), most often on the concave side of the lower, smaller curve near the pelvis. Fu and colleagues found at least one level of severe foraminal stenosis in 97 percent of 36 adults with degenerative scoliosis seeking surgery, with the worst narrowing on the concave side in 83 percent. Age is a strong factor: Hawasli and colleagues found patients 55 or older were about eight times more likely to have radicular pain than younger patients.

I am Dr. Justin Dick at Clear Life Scoliosis and Chiropractic Center in Charlotte, NC. Adult scoliosis with leg pain is common in our office, and the curve on the film often tells me which nerve to examine before the patient points to it.

Why the Concave Side Matters

On the inside (concave) side of a curve, the vertebrae tilt toward each other, the disc space narrows, and the opening for the nerve root shrinks. Pugely and colleagues measured foramina on CT in 48 adults with scoliosis. In 17 of 18 patients with sciatic nerve pain, the narrowed opening was on the concave side of the smaller curve below the main lumbar curve. Symptomatic openings averaged 7.8 mm in height against 12.1 mm for openings without symptoms. Ferrero and colleagues, in 76 surgical patients, also found foraminal and lateral recess stenosis most often in the concavity of the lowest curve, and L5 was the most common painful root at 41 percent.

Radiographic Signs That Predict Leg Pain

Kleimeyer and colleagues studied sideways slipping of one vertebra on another (lateral listhesis) in 189 adults and validated the result in 105 more. Vertebral rotation of grade 2 or more and lateral listhesis at L4-L5 were the strongest predictors. When both were present, 68.4 percent of the first group and 72.7 percent of the validation group had radiculopathy. When neither was present, the rates were 6.4 and 16.7 percent. Hawasli and colleagues found that reduced height between pedicles on routine radiographs matched the side and level of radicular pain. These are findings a standing radiograph can show without an MRI.

Who Is Most at Risk

Hawasli and colleagues reviewed 200 adults with degenerative scoliosis. Sixty had radicular pain. Patients 55 or older had an odds ratio of 7.96 for radicular pain, 5 for motor deficit, and 5.2 for sensory deficit, and lower nerve roots were more often affected. Curves are common at that age: Schwab and colleagues found a curve over 10° in 68 percent of 75 healthy volunteers over 60.

When the Curve Is Not the Cause

Most sciatica in the general population comes from a lumbar disc herniation, and a person with scoliosis can have a disc herniation like anyone else. Jensen and colleagues' BMJ review describes the diagnosis as clinical, based on leg-dominant pain in a nerve root pattern. Teen idiopathic scoliosis rarely produces nerve root pain, so a teenager with a curve and true leg pain or neurological signs needs a different workup. That is my clinical reasoning, and my post on thoracic scoliosiscovers MRI indications in young patients.

How Dr. Justin Dick Evaluates Sciatica in Scoliosis Patients

At our Charlotte office, the workup includes a neurological exam by nerve root, standing radiographs read for rotation, lateral listhesis, and foraminal height when clinically indicated, and MRI review when symptoms or deficits warrant it. Progressive weakness or bladder and bowel changes are referred out urgently. My post on stenosis exercises with scoliosiscovers conservative management.

Comparison

Research and Evidence

Evidence tiering: all scoliosis-specific studies here are retrospective or cross-sectional cohorts, most from surgical populations, which overrepresent severe cases. Kleimeyer included a prospective validation group. Jensen is a narrative review. No randomized trial compares treatments for sciatica specifically caused by adult scoliosis.

My own published work includes older adults with scoliosis. The geriatric case series, Radiographic Sagittal Alignment and Kinetic Chain Alterations in Geriatric Patients With Scoliosis: A Case Series (Cureus, 2026, PMID 42037873), describes two patients, and the de novo scoliosis case describes one adult. Both are case-level evidence.
