BUMAX has been picked as the sole supplier of screws for advanced and durable prosthetic knees by a German manufacturer of a waterproof and submersible prosthesis knee and foot system, WEIGEL+ medical.
BUMAX SDX 109 high strength super duplex fastener was the only screw on the market capable of providing a prosthetic knee joint with the necessary high strength and corrosion resistance to contribute to providing prosthesis solutions to people around the world.
The Niagara Foot is an affordable, high-performance prosthetic foot designed for individuals with active lifestyles brought to the market by WEIGEL+ medical (development and manufacturing) and DOI ortho-innovativ (distribution and education). It will be fitted with BUMAX fasteners for maximum strength and corrosion resistance.
The BUMAX SDX 109 will also be used for the All Terrain Knee, a mechanical prosthetic knee joints used by those with above-knee amputations.
