Freeform modeling of spinal implants

Abstract

To design a customized prosthesis that is tailored to the size and the shape of a unique anatomy provides better medical treatments and outcomes along with improved comfort and quality of life for patients. In this paper an innovative approach to spine implant design is proposed which relies on freeform modeling software and a haptic interface. The system mimics working on a physical replica of the patient’s spine and allows the user to model a prosthesis which might represent a promising concept to fix a curved vertebral column.
