A CAD CAM digitizing adapter for spinal casts

An adapter was designed to hold a negative cast of a torso in position for mechanical digitization. Once a spinal shape is digitized, the data file can be loaded into a CAD CAM system for modification and manufacturing of a positive model for an orthosis. The adapter currently fits a Seattle Digitizer (M+END, Seattle, WA); however, the interface unit can be changed to accommodate other commercial digitizers. By using this adapter, current lower limb prosthetic CAD CAM systems can be used to design and manufacture spinal orthoses.
