A modified brace (Prenyl) for scoliosis

Sixty-six skeletally immature patients with idiopathic scoliosis were treated with a Prenyl brace and their results were analyzed. Fifty-three patients (80%) showed a satisfactory response. The best results were obtained in patients with lumbar curves and thoracolumbar curves less than 40 degrees. Advantages of this brace are simplicity of fabrication and fitting, patient comfort, patient acceptance and relatively low cost. The disadvantages of this brace are that it is less effective in thoracic curves in the upper thoracic spine, double major curves and kyphosis. It probably causes more significant chest restriction than the Milwaukee brace.
