Metacarpal

At Metacarpal, we’re addressing a longstanding challenge in upper-limb prosthetics: many individuals abandon their prosthetic devices—not because they don’t want or need them, but because the technology hasn’t consistently delivered the reliability, control, and practicality required for everyday life.

Our mission is to rebuild that trust by rethinking body-powered technology. The Metacarpal GEM is the world’s first body-powered, multi-articulating prosthetic hand—designed to bridge the gap between traditional body-powered devices and more complex myoelectric systems.

By combining the dependability and proprioceptive feedback of body-powered control with modern hand functionality, the GEM offers a solution that is intuitive, durable, and immediately functional. It is optimized for real-world use—prioritizing comfort, control, and reliability so clinicians can fit patients quickly and users can trust their prosthesis in daily life.

At Metacarpal, we believe that when a prosthetic truly works—when it is dependable, practical, and responsive—people choose to wear it. And when that happens, confidence, independence, and quality of life follow.
