Introduction: 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.
Methodology: We describe the different steps to design and manufacture braces used for spinal deformities.
Results: Our prospective evaluation showed good results in terms of the correction achieved and regarding patients' in-brace comfort.
Discussion: 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.
