Great progress has been made in standardizing 2D medical images, but the standardization of 3D medical models is still lacking. The first Web extra at http://youtu.be/J_h3Pcono7A is a video in which a shoulder muscle is rendered based on a fresh cadaver and then laid out on a computer. The pattern is then applied to a 3D model of a shoulder, with corresponding muscle layers and connections to the bones. The second Web extra at http://youtu.be/u5eVGIuhPUA is a video in which flexion and extension range of motion and movement of the upper arm are applied to a 3D model. The third Web extra http://youtu.be/wS4NPn08NKI is a video rendering showing liquid simulation for realistic virtual surgery and medical communication. The fourth Web extra at http://youtu.be/YZ5PWZyS4E0 is a video rendering showing a colon cancer surgery simulation for realistic virtual surgery and medical communication. The fifth Web extra at http://youtu.be/QN5iJhX8PQ4 is a video rendering showing an arthroscopic surgery simulation for realistic virtual surgery and medical communication.
