Area of Science:

  • Biomedical Engineering
  • Neuroprosthetics
  • Rehabilitation Technology

Background:

  • The FreeHand system is an implantable neuroprosthesis for restoring upper limb function in tetraplegia.
  • Traditional implantation involved multiple large incisions, potentially leading to complications.

Purpose of the Study:

  • To describe a novel percutaneous electrode placement technique for the FreeHand system.
  • To evaluate the benefits of this minimally invasive approach.

Main Methods:

  • Utilized recently developed intramuscular electrodes for electrode placement.
  • Employed a percutaneous technique to minimize surgical invasiveness.

Main Results:

  • The percutaneous technique significantly reduces the number and size of incisions.

  • This approach decreases operative time and patient morbidity.
  • Minimizing tendon adhesions leads to improved functional outcomes.

    • Conclusions:

    • Percutaneous electrode placement for the FreeHand system offers a less invasive and more effective implantation method.
    • This advancement enhances the potential for restoring grasp and pinch in individuals with tetraplegia.
