Wrists

The wrist is a diarthrodial anatomical joint consisting of 8 small bones (scaphoid, capitate, hamate, lunate, trapezium, trapezoid, triquetrum, pisiform) and 7 long bones (radius, ulna, and 5 metacarpals). When subject to injury and disease the wrist undergoes changes in kinematics, inter-bone joint space areas, cartilage thickness, length of ligament paths, etc. Developing computational tools for the analysis of anatomical joint characteristics is important in understanding the cause of injury, tracing the progress of disease, and taking preventative measures.
