Shape geometry evaluation of rigid bracewear for children with scoliosis

Scoliosis is a three-dimensional spinal deformity which is usually found during the years of skeletal growth. Among the options available for managing spinal disorders in children are observation, bracing, and surgery, depending on the Cobb's angle when detected. The brace can allow continued spinal growth while preventing spinal deformity from worsening. However, the process of making rigid bracewear is complex, and depends on the experience of practitioners. This study therefore aims to propose an objective approach to quantify the 3D shape geometry and rectifications of the bracewear development process. The results indicate that the amount of rectifications made on casting models result in major body dimensional changes to the wearer, which has been increased by 2 to 7 times. The findings therefore provide a reference for orthotists to effectively control scoliosis.
