Chêneau bracing associated with halting curve progression for adolescent idiopathic scoliosis

Researchers investigating the effect of Chêneau bracing on the coronal and sagittal alignment of patients with adolescent idiopathic scoliosis found the brace can be useful for the prevention of curvature progression, but varies in the treatment of pelvic and sagittal alignment.
Researchers retrospectively reviewed information for patients with adolescent idiopathic scoliosis (AIS) who were at high risk for curve progression. Thirty-two patients treated at the authors’ institution between 2005 and 2012 who were prescribed a Chêneau brace and instructed to wear it for at least 23 hours each day were included in the final patient cohort. At the time of bracing, the average patient age was 12.9 years. Patients were treated for an average of 24.4 months.
No statistically significant change in Cobb angles were noted at final follow-up. Pelvic incidence increased in 28% of the cases and stayed the same in 59%. Lumbar lordosis and thoracic kyphosis both significantly decreased in the patient cohort, but the sagittal vertical axis significantly increased from a mean of -44 mm to -30.2 mm. The patients also experienced a significant increase of their pelvic tilt from 4.5° to 8.3°, according to the study. – by Robert Linnehan
