Abstract

CHIDOS is a web application that conducts artificial intelligence (AI) - empowered customization and Finite Element Analysis optimization (FEA) of additively-manufactured hip implants used in total hip arthroplasty. The medical practitioner only creates a patient profile, uploads the patient’s CT scans and confirms the anatomical landmarks that are necessary for the restoration of the patient’s hip biomechanics. Based on this information, CHIDOS automatically reconstructs the anatomy of the patient’s pelvic and femoral bones in a 3D digital environment, develops a patient-specific femoral stem as well as patient-specific surgical tools (i.e., broach/rasp, osteotomy guide) used in total hip arthroplasty, optimizes the implant’s design, and creates accompanying 3D documentation & 3D anatomical models of the hip joint, useful for preoperative planning and intra-operative guidance. The patient-specific femoral stem developed may be combined with several commercial acetabular cups and femoral heads based on patient’s needs and surgeon’s experience. The reconstructed femoral stem, anatomical models and the surgical tools are all designed in a completely automated pipeline and produced via additive manufacturing.
