18-year old Moises Campos had suffered a tibial tubercle fracture during his youth, which resulted in a growth arrest below his kneecap and a deformity of his tibia. Before his actual surgery, the Children’s Hospital of Orange County (CHOC) recently teamed up with Dinsmore Inc., a 3D printing company from Irvine, California, to 3D print a full-scale model of Campos’ tibia based off his CT scan using stereolithography (SLA).
