what is metacarpal?

Metacarpal sees elegance in engineering. We make fully body-powered yet bionic, prosthetic hands. That means zero electronics. 

All of the functionality you see is generated by the user, giving the most intuitive and practical operation.

how are we different?

What separates Metacarpal's body-powered hand from those already on the market? Our unique focus on high-performance engineering has lead to a series of innovations that increase the functional capacity of the hand

adaptable grasp

5-finger design automatically adjusts grasp around any shape of object

fluid motion

effortless to learn and operate

variable grips

enables the user to switch grips for different operations

why did we make it this way?

For the last 30 years, the upper-limb prosthetics industry has been entirely focused on making advanced robotic hands. But, despite all of this effort, simple body-powered hooks that have been around since the Titanic sank, remain the most functional products.

We take a new approach, looking at the principle that makes the hooks so inherently functional, and upgrading it with a series of engineering innovations - creating a product with greater function that users can be proud to wear!

how can you get one?

Are you an amputee or a clinician looking to get hold of a Metacarpal hand? Please get in touch. They are still in development and so not yet available, but getting in touch means you can:

- Have an impact on the design
- Get access to early release products for trialling
- Hear when products become available

About us

At Metacarpal we want to make the best prosthesis possible. This means a functional device, that's comfortable to wear all day long, accessible pricing and looks so good that it makes you feel good. We achieve this with better materials, and more advanced engineering than competitors.
