The duPont kyphosis brace for the treatment of adolescent Scheuermann kyphosis.

The purpose of this study was to evaluate the effectiveness of a newly designed brace in the treatment of adolescent Scheuermann thoracic kyphosis. Twenty-two children who met the roentgenographic criteria of Scheuermann kyphosis and were compliant with treatment were followed until skeletal maturity. Sixteen patients (73%) showed nonprogression of their kyphosis (nine patients demonstrated an improvement, seven patients remained unchanged), and had a mean improvement of 9 degrees (64 degrees to 55 degrees). Six patients (27%) demonstrated progression of the kyphosis and had a mean increase in their kyphosis of 9 degrees (59 degrees to 68 degrees). One patient underwent posterior spinal fusion for progressive thoracic kyphosis despite bracing. It was recommended that this brace be worn until skeletal maturity; in this study this time period was determined to be at least 16 months to induce improvement or halt progression of this disease. Flexible curves are a positive predictor of a successful outcome of bracing with the kyphosis brace. These results are comparable to previous reports in the literature describing the effectiveness of the modified Milwaukee brace in the treatment of Scheuermann thoracic kyphosis prior to skeletal maturity, and the kyphosis brace has the advantage of concealability under normal attire.
