Anatomical flexion and rotation around the MCP joint
Low weight, high strength

The Point Thumb is a heavy-duty, passive articulating prosthetic thumb designed to be both lightweight and strong, using a novel ratcheting mechanism to lock into 11 unique positions of flexion.
Point Designs' prosthetic thumb is designed for patients with thumb loss who require a durable device and the ability for one-handed operation and various levels of flexion. The prosthesis is made of titanium and stainless steel, and comes with all necessary hardware for integration into a prosthetic socket.
Our thumb prosthesis is designed for people who have lost their thumb at or near the metacarpophalangeal (MCP) joint. It is a mechanical, passive device with a robust construction. The Point Thumb empowers people with partial thumb amputation by giving them more mobility, function, and independence.
The main features of the Point Thumb include:
To operate the Point Thumb, the user positions the thumb into one of the 11 locking levels of flexion by pushing the dorsal side against an opposing surface (e.g., table, thigh, etc.). The device locks into place automatically, enabling the individual to perform their desired task.
There are two methods to extend the digit:
Each thumb fitting requires 1 mounting bracket
Alignment tools included
Lamination spacers and mounting hardware included
Allows dynamic fitting
