A robust, custom, functional solution.
The MCPDriver is designed for individuals with amputations through the proximal phalanx. The MCPDriver restores the middle and distal phalanges. These body-driven, articulating devices allow patients to regain fine dexterity and natural grip patterns. The MCPDriver excels at restoring pinch, key, cylindrical, and power grasps, as well as grip stability. Each device is custom-designed to within millimeters of a patient’s unique anatomy to successfully mimic the complex function of a finger.
The MCPDriver gets its strength from a combination of rigid stainless steel linkages driven by the residuum and is comfortably anchored on the dorsal surface of the hand. The functional force at the fingertip is dependent on the patient’s input force. A typical male can achieve 7-9lb force at each fingertip. Additionally, the power hook grasp posture allows patients to lift objects of substantial weight as the load transfers efficiently to the suspension about the wrist.
The MCPDriver is driven by an intact MCP joint with enough residuum distal to the joint to engage the ring. For an amputee who doesn’t meet these minimum requirements, it is still possible to obtain functional benefits from this device. However, special consideration will have to be made prior to ordering the prosthesis.
OTHER DESIGN FEATURES INCLUDE:
- Silicone backplate interface for increased comfort and protection.
- Interchangeable suspension rings to allow the patient and prosthetists to find the ideal fit for the user.
- Shims that can be added or removed to fine-tune the fit as needed by the patient due to volume fluctuation or preference.
- Abduction/adduction washers allow the prosthetist to adjust the mechanical finger. The freedom of motion in this component helps the patient gain optimal grip.
- Twelve unique color choices and silicone backplate pairings allow patients to customize devices to meet their style preferences.
- Silicone tip resembles the natural fingertip and provides added grip.
- The cage-like structure of the stainless-steel linkages provides protection for the hypersensitive residuum.

How to get the MCPDriver
Once insurance approval has been obtained the prosthetist will request a Naked Prosthetics sizing kit and complete a full evaluation of the patient. Using the sizing kit, the prosthetist will complete the intake forms as directed and submit all information to Naked Prosthetics where our engineers will design and manufacture a custom, functional finger prosthesis individualized for the patient’s needs and anatomy.
“I use to be the guy in the room with the missing fingers, now I’m the guy with the cool hand!” – Nick, four MCPDrivers
“It is important to learn new skills after hand trauma,” he explains. “After a loss is the best time to explore something new because there is no benchmark of success to meet. You have to find your new normal in the little things.”
“You may feel hopeless in the moment, but it does get better. And you will be surprised at what you could learn. I am a different person now and I grew from the experience.”
"I am confident that I can do more things and then some with this new opportunity given to me—to inspire others who are just like me and to show them that for every setback, there is a major comeback!"
“It sounds cheesy and it really just takes time. You just have to see that it isn’t the end of the world. It could’ve been worse. Considering everything, it’s a small part of my life. I could’ve lost my hand, my arm. If you could see my truck, I don’t even know how I survived.”
"It’s a game changer for me. 20 years ago, as a freshly injured kid walking into a prosthetist’s office and being completely disheartened about what was available to help replace my fingers. Now, I finally have something that makes me feel like I have a bit of a whole hand again.”
