Long term functional outcome of severe cervical cord injury is most often poor. According to our surgical results, an emergency operation for a compressive and unstable cervical spine provides a better outcome for cervical cord injury patients. Follow up of our cases did not show any change in the neurological status as per Frankel's classification, but there was some change as per Zancolli's classification. Treatment of this severe cervical cord injury was not completed because the patients residual function could not be properly restored. To implant FES of Free Hand system, we selected the patients with C5 burst fracture (Frankel A), whose neurological deficits did not improve after the conventional rehabilition. This system consists of completely implanted electrodes, stimulator and an external computer control unit. Free Hand system provides lateral and palmar grasp function for the ipsilateral hand. Lateral grasp provides pinch function between thumb and index finger. Palmar grasp provides grasp function between thumb and four fingers. After 5 months of therapeutic electrical stimulation (TES) training, FES was started. The motor function of the patients showed improvement and he could hold spoon, pen and small glass 10 months after the implant. Free Hand system seems to be very helpful to restore useful upper motor function after severe cervical cord injury.
