Background and aim

The purpose of this paper is to share with scoliosis professionals the X-rays of different pad placement levels associated with improved curve correction in a case of idiopathic scoliosis (IS). Scoliosis braces of all types and brands utilize common principles of construction that ensure good fit and function. Equally important to the end result is good patient follow-up care and brace quality control by the orthotist.

Design and methods

This report reviewed the case of an 11-year-old girl diagnosed with IS, focusing on the in and out-of-brace x-rays, as well as the fit and function of the braces. The first brace was a TLSO-type, the second a Cheneau-type brace using a B1 model following the Rigo classification of scoliosis.


The first TLSO-type brace presented an in-brace X-ray that showed a curve increase. The Cheneau-type scoliosis brace reduced the Cobb angles over 50%.


The biomechanical changes consequent to modifications in brace design and pad placements appeared to have improved the scoliosis and reduced the Cobb angles in this case. An orthotist must provide optimal fit and function of the brace which was prescribed by the referring physician. Adherence to certain basic design principles, and close follow up by the orthotist-especially during growth spurts - are critical to its effectiveness. Specifically, a skilled orthotist must be experienced with the particular brace-type, apply these principles, maintain a good working relationship with both physician and patient to ensure timely brace adjustments essential to continued brace comfort and efficacy.
