As of 2018, there are only standard sized, cast molded hips available to patients requiring hip implants. However, everyone has a unique body, so a cast molded hip implant will fit people differently. Personalized additively manufactured, or 3D-printed, implants created from a patient’s own computerized tomography (CT) or magnetic resonance imaging (MRI) images may provide numerous benefits. A main benefit would be that the implant would provide a personalized fit for the patient, as it would be made from scans of his or her own body. With a personalized fit, there would be reduced surgery and recovery time. For people with a physiological abnormality, a customized solution may be printed for reconstructive surgery. Another benefit would be for surgeons who could 3D print their patient’s bone for pre-surgical planning, such as planning screw placements. As the baby boomer population ages, the commercial market for 3D-printed joint replacements is expected to soar over the next decade. The goal of the research conducted here is to demonstrate a prototype process for patient specific, additively manufactured hip implants made from Digital Imaging and Communications (DICOM) images of human femur bone, leading to additional research on imaging of trabecular bone for biomimetic lattice development.
