An Investigation of the Coupling Function of the FDS and FDP Tendons After Ulnar Superficial Slip Resection

The goal of this study is to assess kinematic changes in the flexion pattern of a digit after resection of a single arm of the FDS tendon (ulnar superficialis slip resection or USSR). Angular joint displacement as a function of a controlled tendon excursion driven by computerized motors was used to quantify the kinematics of the finger. This series of experiments was performed on fresh-frozen cadaver hands, and data was acquired in real time using a National Instruments DAQ card and a PC running LabView software.
