Scoliosis Bracing
Rigo-Chêneau Brace
A surgeon's overview of the Rigo-Chêneau brace — a three-dimensional, curve-specific approach to scoliosis bracing, and what the evidence shows.
The Rigo-Chêneau brace represents a particular philosophy of bracing: rather than simply pushing a curve towards the midline, it aims to correct scoliosis in three dimensions and to actively reshape the trunk. As a spinal surgeon I prescribe braces and monitor the spine, but the design and fabrication are the work of specialist orthotists trained in this method. This page explains what the Rigo-Chêneau brace is, how it differs from a standard brace, and what the evidence tells us.

What the Rigo-Chêneau brace is
The Chêneau brace was developed in Europe and later refined by Manuel Rigo into the Rigo System Chêneau, an asymmetric, curve-specific thoracolumbosacral orthosis. Unlike a simple symmetrical shell, it is built around a detailed classification of the individual's curve pattern, with pressure zones and, importantly, generous expansion voids into which the corrected trunk can move. The intention is a genuinely three-dimensional correction of what is a three-dimensional deformity.
How it works
The brace applies corrective pressure over the convexities of the curve while deliberately leaving open spaces on the concave side, encouraging the spine, ribs and trunk to derotate and shift towards a more balanced shape. It is often used together with scoliosis-specific physiotherapy exercises, which are delivered by specialist physiotherapists. It is generally prescribed for full-time or near full-time wear, with results, as for rigid bracing in general, depending heavily on the hours actually worn.
Who it is for
The Rigo-Chêneau approach is used for growing children and adolescents with idiopathic scoliosis, typically in the moderate, progressing range where bracing is indicated. As always, the suitability of any particular brace depends on the individual curve, the growth remaining and the young person's circumstances, which is what a specialist assessment establishes.
What the evidence shows
Studies of Rigo-Chêneau and Chêneau-type braces report good in-brace correction and satisfactory outcomes when patients are selected and monitored well. Series applying the strict Scoliosis Research Society inclusion criteria have shown curve stabilisation or improvement in most patients, and long-term work has suggested the brace can help many patients avoid surgery. Correction tends to be greater for thoracolumbar and lumbar curves than for thoracic or double curves. A high initial in-brace correction, a more mature skeleton with a lower Cobb angle, and good compliance with both brace and exercises are associated with success. Comparative studies of Rigo-Chêneau against Boston-style braces have not established one as clearly superior; the consistent message across all brace research is that wear time and good in-brace correction matter most.
What to expect
The brace is custom-designed from a scan or cast of the trunk, fitted and adjusted by a specialist orthotist, and reviewed in clinic with periodic X-rays. It is often paired with scoliosis-specific exercises. As with any rigid brace it is worn until skeletal maturity and then gradually withdrawn, with the spine monitored throughout.

Every patient is different, and investigations, treatment options, potential risks, expected recovery and outcomes depend upon an individual's diagnosis, symptoms, medical history, examination findings, skeletal maturity, curve pattern and personal circumstances. A brace should be prescribed and monitored by a specialist team and designed and fitted by a qualified orthotist. Decisions regarding treatment should always be made following consultation with your treating spinal surgeon or healthcare professional.
