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.

Overall Pipeline

1. Data acquisition
2. Segmentation of neutral wrist
3. Registration of non-neutral positions
4. Retrieval of kinematics
5. Inter-bone joint space area calculations
6. Ligament path calculations
7. Cartilage maps (location & thickness)
8. Cartilage surface deformations
9. Joint simulation

Tools
