Traditional scoliosis braces are typically crafted from customized casts or molds made of the patient's trunk. More recently, computer aided design/computer aided manufacture (CAD/CAM) and other computer technology has been introduced in order to try to eliminate this close physical contact and minimize the variability of orthotists' skills. The purpose of the present study is to report on the preliminary experience with the Los Angeles brace™, a new CAD/CAM brace.
This was a retrospective review of forty adolescent idiopathic scoliosis patients who completed treatment with this new CAD/CAM brace. Initial Cobb magnitude of the primary curve averaged thirty degrees (range 25–40 degrees). The distribution of curve patterns included one lumbar, eleven thoracolumbar, eight thoracic, and twenty double major curves. The brace is an asymmetric, underarm thoracolumbar sacral orthosis (TLSO) that uses computer models and algorithm generated predictions in its construction.
In-brace correction averaged fifty-one percent for the primary curves, with corrections of fifty-three and twenty-two percent for girls and boys, respectively. Average followup was twenty months since brace discontinuation. Six patients (fifteen percent) experienced curvature progression at the completion of bracing.
