Example of a patient with an overcorrection in a Chêneau light brace. Overcorrection of a thoracic curve from 38° to -14° in a T2 „Chêneau light" model in an 11-year old premenstrual girl with Tanner II. For the measurement of the corrected curve the neutral vertebra of this X-ray was used. If we would have taken the neutral vertebrae of the previous X-ray the correction effect would have been less important.
