3D printing has changed the way scoliosis braces are made – in the past, they were bulky, uncomfortable contraptions, but 3D printing has allowed them to be made much more lightweight and form-fitting. The PAMIS project is working to improve scoliosis surgery through the development of 3D printed implants. Typically, scoliosis surgery involves the implantation of standard straight and flat metallic straps that are screwed to the spine. The standard sizes and shapes of these implants can be problematic, as no one’s anatomy is exactly the same, and can result in complications or even the need for revision surgery in the future. “It is as well an opportunity to take advantage of the ‘digital twin’ concept to prepare scoliosis surgery and implants,” the PAMIS project leaders state. “This pairing of the virtual and physical worlds allows heading off problems before they even occur in the surgery. The virtual human model concept and new definition of bio-inspired 3D printed parts for scoliosis could open the way to the definition of other lines of orthopedic implants and the application of materials better suited to the specific stress to correct in each case.” 3D printing and digital design can eliminate the need for revision surgery so that even those with the most serious cases of scoliosis can go on to lead normal, healthy lives.
