Understanding scoliosis as a three-dimensional condition

Scoliosis isn’t just a side-to-side curve of the spine. It’s a complex, three-dimensional condition that also involves twisting (rotation) and changes to the spine’s natural front-to-back alignment.

To treat scoliosis effectively, all three of these elements must be addressed, not just the visible curve.

The LOC Scoliosis Brace is specifically engineered to correct all three components of the deformity:

  • Coronal (sideways): straightening the curve
  • Sagittal (front-to-back): restoring natural spinal posture
  • Axial (rotational): reducing the twist that causes rib prominence and trunk imbalance

Correcting spinal curves beyond the Cobb angle

Scoliosis is often described using the Cobb angle, which shows how far the spine bends sideways on an X-ray. But scoliosis is three-dimensional, and can also involve rotation and changes in overall spinal balance.

This rotation, sometimes described as axial vertebral rotation (AVR), can contribute to visible changes such as a rib prominence, uneven shoulders, and trunk asymmetry.

If imaging is needed to support brace fitting or review, we may refer patients to an independent EOS 3D imaging provider, where an ultra-low-dose scan can create a 3D model of the spine while the patient is standing.

Imaging is performed and reported by the external provider and the clinical team. We do not provide radiology or diagnostic imaging reports. Where measurements are included in medical reports, we use them to help review orthotic fit and inform brace adjustments over time.

EOS imaging can provide measurements of both the sideways curve and rotational elements in reports from the imaging provider and clinical team. Where these measurements are available, we use them to support orthotic fit review and brace adjustment. We do not provide radiology or diagnostic imaging reports.

3D correction you can measure

For patients who have EOS scans both before and during bracing, we can track real 3D changes in the spine, not just improvements in the Cobb angle.

This technology provides a low-dose image that shows how the LOC Scoliosis Brace influences the spine in the coronal, sagittal, and axial planes.

The data helps us see how each brace actively straightens and de-rotates the spine in real time. In clinic, we combine this with physical assessment, particularly the Angle of Trunk Rotation (ATR) measured using the Adam’s forward-bend test.

Together, these tools let us monitor progress across all three planes, ensuring every patient’s brace is working as effectively as possible.

Clinical results and evidence: measurable 3D improvement

Our own published research using EOS 3D imaging has shown how effectively the LOC Scoliosis Brace corrects spinal alignment in all three planes.

In a review of patients aged 10 to 16 with moderate to severe adolescent idiopathic scoliosis, each fitted with a bespoke LOC Scoliosis Brace, we compared spinal alignment before and during bracing.

  • Axial vertebral rotation (spinal twist): reduced by an average of 73% when wearing the brace
  • Coronal correction (side-to-side curve): significant straightening observed in every patient
  • Overall result: every case showed measurable improvement in both spinal alignment and rotation.

These findings confirm that the LOC Scoliosis Brace achieves true three-dimensional correction, not simply curve stabilisation.

By actively straightening and de-rotating the spine, the brace delivers measurable, cosmetic, and structural benefits that go beyond traditional bracing outcomes.
