Abstract

This study was conducted to better define normal carpal kinematics and evaluate the effect that dynamic fixators have on normal carpal kinematics. Four fresh frozen cadaver upper extremities were studied. Optoelectronic stereocinephotogrammetry motion analysis (OSMA) was performed on the normal wrist during a flexion/extension (f/e) motion. Then three different external fixators were placed on the extremity, and the kinematic analysis run again with each fixator attached and used in a dynamic mode. Range of motion (ROM), angles between bones, and instantaneous screw axes (ISA) were calculated for each condition (normal and with each fixator attached).
