Abstract
This paper presents a three-dimensional (3D) multibody model of the cervical spine implanted with an artificial disc. The model was used to predict prosthesis placement influence on the resulting cervical kinematics in a series of patients. The vertebral tract modeled was the C2-C7, and the vertebral geometries were reconstructed from computed tomography (CT) images. The model was used to simulate the flexion-extension motion of the cervical spine in 10 patients implanted with the Prestige commercial disc prosthesis at a single level. For each patient, a geometrical model of the prosthesis was scaled and included in the multibody model to match the size and positioning of the actual prosthesis, as assessed on post-operative radiographs. Simulations of complete flexion-extension were carried out for each patient, and the main parameters relevant to the motion of the vertebral bodies were calculated and compared to data measured from dynamic post-operative radiographs. At the implanted level, the simulated ranges of motion generally agreed with the measured ones, with an average deviation
