Dextroscoliosis vs Levoscoliosis Charlotte NC | Reading Your X-Ray Report | Clear Life Scoliosis

By Dr. Justin Dick, DC · Clear Life Scoliosis and Chiropractic Center, Charlotte, NC · Published October 22, 2026

Dextroscoliosis means the spine curves with its convex side, the outside of the bend, pointing to the patient's right. Levoscoliosis means the convex side points to the left. "Dextroconvex" and "levoconvex" say the same thing more explicitly. The words describe direction only. They do not tell you how large the curve is, whether it is structural, or what caused it.

I am Dr. Justin Dick, and I hold CNMT and ARRT(N)(CT) imaging credentials. At Clear Life Scoliosis and Chiropractic Center in Charlotte, NC, patients often arrive with a radiology report that says "mild dextroscoliosis" and nothing else. This post explains what that phrase does and does not tell you, and the situations where direction actually changes what happens next.

How Direction Is Named

Direction is named for the convex side, the side the curve bulges toward. A thoracic curve bulging to the right is a right thoracic curve, or a thoracic dextroscoliosis. A lumbar curve bulging to the left is a left lumbar curve, or a lumbar levoscoliosis. Many spines have both, which is why a report can mention dextroscoliosis and levoscoliosis in the same sentence. My post on double major and S-shaped curves covers spines with two structural curves.

Direction is described from the patient's perspective. Radiographs are viewed with a marker that shows which side is which, and a mislabeled or flipped image can reverse the reported direction. That is uncommon, but it is one more reason I review the images, not just the report.

What "Mild Dextroscoliosis" on a Report Leaves Out

A one-line impression on a chest X-ray, abdominal film, or CT scan was usually written by a radiologist looking for something else. It rarely includes a Cobb angle, rotation, curve location, or whether the film was standing. "Mild" in that context is a visual impression, not a measurement. To decide anything, you need a standing radiograph with a measured Cobb angle and a clinical exam. My post on scoliosis misdiagnosis covers why measurement method matters.

A small lateral bend on a supine film taken for another reason may not be a structural scoliosis at all. The standard definition requires a Cobb angle of 10° or more with rotation, as discussed in my post on postural versus structural curves.

When Direction Changes the Workup

Direction matters in specific combinations. In Xu and colleagues' 2020 study of 714 adolescents with scoliosis who had whole-spine MRI, a left thoracic curve, meaning a thoracic levoscoliosis, was an independent risk factor for an intramedullary spinal cord abnormality, along with male sex, a sharply angled curve, abnormal abdominal reflexes, and ankle clonus. In Zhang and colleagues' MRI study of 504 children under 10 with presumed idiopathic scoliosis, both left thoracic curves and right lumbar curves were associated with neural axis abnormalities.

So a thoracic levoscoliosis or a lumbar dextroscoliosis in a young patient, particularly a boy or anyone with neurological findings, is a reason for MRI and a medical referral before an idiopathic plan begins. Those studies come from hospital cohorts that likely include more complex cases than a typical practice, so the percentages overstate the risk for an average patient. The direction of the association is consistent. My post on thoracic scoliosis covers this in more detail.

Direction in Adults

In adults, the report's direction mostly matters for planning: which side of the lumbar spine is loaded, where nerve openings may narrow, and how the pelvis is tilted. My posts on spinal stenosis with scoliosis and pelvic tilt cover those mechanics. Direction alone does not predict pain.

How Dr. Justin Dick Reads Direction at Clear Life

At our Charlotte office, a report that mentions dextroscoliosis or levoscoliosis leads to a standing PA and lateral study when one is not already available, with each curve's location, direction, Cobb angle, and rotation recorded. Direction is then read against age, sex, and the neurological exam. An atypical direction pattern with any red flag goes to MRI first. You can also listen to our podcast episode on dextroscoliosis.

Comparison

Research and Evidence

Evidence tiering: the direction-related MRI associations come from two retrospective hospital cohorts with likely referral bias. The definitions of direction are standard terminology. The point that incidental reports rarely include measurements is my clinical observation from reviewing outside imaging.

My own published work uses measured, direction-specific curve data. The Lenke 5C case report, A Non-surgical Multimodal Approach to Adolescent Idiopathic Scoliosis (Lenke 5C) Using an Intensive Two-Week CLEAR Institute Protocol: A Report of Two Cases (Cureus, 2026, PMID 41640942), and the cervical mechanics study, A Retrospective Cross-Sectional Analysis of Abnormal Cervical Mechanics in Patients With Scoliosis (Cureus, 2025, PMID 41018459), both report Cobb angles measured on standing radiographs.
