The Journey To Developing HyperFlex®
Dr. Josef Geldwert developed his innovative HyperFlex™ technology to offer a safer, less invasive alternative to traditional bunion surgery—one that avoids breaking or removing bone. Inspired by the mini-tightrope procedure that gained popularity around 2010, Dr. Geldwert recognized the technique’s promise but also its severe limitations, including damage to the second metatarsal and surrounding soft tissue.
With HyperFlex™, he refined the concept to eliminate those risks, creating a procedure that preserves bone integrity, prevents trauma to the foot, and promotes faster healing. This advanced approach allows patients to regain mobility much more quickly while protecting the bone and tissue structures in their foot long term.
