The Strasbourg Fractomed brace is a TLSO used since 1980 for the treatment of flexible scoliosis of the adolescent. This brace is made with an original material: Polyvinyl alcohol. This porous foam, rigid at room temperature, is moldable with steam, a property which allows one to mold the brace directly on the patient, without a plaster mold. Making a Strasbourg brace is rapid, and no specific equipment is required, so that this brace can be realized in a hospital cast room. Reduction of the scoliosis is adapted from the EDF technique, achieved supine on a traction table. After initial hardening of the brace, modifications or additional corrections can be made, since the properties of the material persist, whatever the number of moldings. The Strasbourg brace is efficient for the treatment of 15° to 35° curves, with a residual flexibility of more than 50%, and an apex not located above T7.
