Overview
Naked Prosthetics manufactures durable, custom, functional finger prostheses specifically for partial hand amputation. Thier mission is to support people with finger amputation and to positively impact their lives by providing functional, high-quality finger prostheses. Thier devices aim to restore the user’s ability to perform daily tasks, supporting job retention and encouraging an active lifestyle.
Products
MCPDriver
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.
- Ten 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.
PIPDriver
The PIPDriver is designed for individuals who have an amputation at the middle of distal phalanx. As an articulating, body-driven prosthesis, the PIPDriver restores length, provides dexterity, replaces a missing DIP joint, and protects sensitive residua. Each device is custom-designed and fabricated to within millimeters of a patient’s unique anatomy to successfully mimic the complex motion of a finger.
The PIPDriver gets its strength from a rigid linkage driven by the residuum and is self-suspended comfortably on the base of the finger. We accurately align the prosthetic joints with the patient’s anatomic ones to provide the most natural motion and form possible.

OTHER DESIGN FEATURES INCLUDE:
- Custom-designed to fit comfortably and suit daily needs
- Easy to don, doff, clean, and care for
- Made from strong and durable medical-grade nylon 12
- Cage-like structure protects residuum
- Slender and sleek design allows for wearing of multiple devices
- Conforming silicone rubber tip pads resemble the natural fingertip
- Lightweight titanium fasteners
- Ten different color coating styles
- Two nail bed design options
ThumbDriver
The thumb is arguably the most important digit of the hand. The newest product in our lineup shares its heritage with the MCPDriver. It features a unique anchor design that tracks the patient’s natural CMC motion and provides a rigid structure to react to the heavy forces generated by opposition. The tip has an adjustable preflex and articulates more subtly than in the MCPDriver. Each device is custom-designed to within millimeters of a patient’s unique anatomy.
The fingers are designed to work uniquely with the thumb in opposition. The ThumbDriver restores the ability of the hand to make a multitude of opposition grasps by providing IP joint flexion and tracking of the complex multi-axial motion of the thumb.
The ThumbDriver is driven primarily by the CMC, and secondarily by the MCP joint in the thumb. The MCP joint provides articulation of the unit, but most function comes from the CMC tracking in opposition. The patient must have enough residuum to engage the ring. For an amputee who doesn’t meet the minimum requirements, it is still possible to obtain functional benefits from the device. However, special considerations will have to be made prior to ordering the prosthesis.

- Ten unique color choices and silicone backplate pairings allow patients to customize their 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 increased protection for the residuum and distal end of the amputation, which can often be hypersensitive.
- The unique hinges and backplate washer allow the ThumbDriver to track the natural multi-axial motion of the thumb complex.
