Abstract

The three-dimensional kinematic analysis of the wrist is a complex problem. A method utilizing high speed stereocinematography has been developed to accurately measure the motion of the bones in the wrist. Both relative and absolute motions can be obtained using this system. The system has been shown to accurately locate a point to ± 0.003 inch. The three-dimensional motion characteristics of the capitate in radial ulnar deviation were analyzed using this system, and the results are presented. A computer graphics program, developed by the authors, is used to display the motion characteristics of the carpal bones. In this program, the bone surface, defined using a special stereopointer and bicubic surface fitting algorithms, is displayed along with the kinematic data.
