Tridimensional trunk surface acquisition for brace manufacturing in idiopathic scoliosis.

Abstract

Brace manufacturing for idiopathic scoliosis requires trunk surface acquisition. Two methods are currently available to design the trunk shape: craft made technique based on a plaster mold and computer-aided design with 3-D reconstruction of the trunk by optical scanning. The objective of the present review was to compare these two methods. We describe the different steps to design and manufacture braces used for spinal deformities. Our prospective evaluation showed good results in terms of the correction achieved and regarding patients' in-brace comfort. Optical scanning for computer-aided design and manufacturing (CAD-CAM) of trunk orthoses have proven their effectiveness. These technologies may help in monitoring conservative treatment and may enhance the brace interaction with the spinal deformity when orthopedic treatment is indicated.
