This device is driven by an intact PIP joint with enough residuum to engage the cage. For a person with finger or partial-hand limb difference who doesn’t meet the typical requirements for the PIPDriver, it is still possible to obtain functional benefit from an added device. Our engineers customise the design to fit your patient, resulting in a functional device. Our intake form will explain to you the steps of ordering a device using a Naked Prosthetics sizing kit, submitting detailed pictures of both hands, and a video showing range of motion.
