3. The wrist positions analyzed in the present study were distributed throughout the range of motion. Joseph J. Crisco et al. J Bone Joint Surg Am 2005;87:2729- 2740 ©2005 by The Journal of Bone and Joint Surgery, Inc.

4. The direction of carpal bone rotation at each wrist position (see Figure 2) was visualized by plotting the directions of the rotation axes for the capitate (A), scaphoid (B), and lunate (C).

5. Three views of the scaphoid, lunate, capitate, and distal parts of the radius and ulna in wrist positions of flexion and extension (A), radial and ulnar deviation (B), dart thrower's radial extension and ulnar flexion (C), and radial flexion and ulnar exten...
