title: The sacroiliac spine - computer simulation of motion and modeling of the ligaments.
abstract: Using an interactive, 3D, kinematic simulation of the human skeleton, the motion of the sacro-iliac (SI) joint is modeled based upon descriptions available in the literature. The major ligaments are added to the simulation data structure using deformable cubic B-spline curve paths. Ligament strains were generated and studied in response to the motion simulations. Results improve our understanding of sacro-iliac kinematics and highlight the importance of further studies to elucidate pathological as well as normal SI joint and ligament function.
