Expert Interview: Dr. Josef Geldwert, Creator of the HyperFlex® Bunion Correction Device
With more than four decades of experience in podiatric surgery, Dr. Josef Geldwert has built a reputation as a pioneer in advanced foot and ankle care. As the creator of the HyperFlex® Bunion Correction System, the least-invasive surgical option for mild to moderate bunions, he is reshaping how bunions are treated by making recovery faster, less invasive, and more aligned with modern patient lifestyles. In this conversation, he shares how innovation in healthcare mirrors personalization trends seen in companies like Gainful.
Q: What inspired you to develop the HyperFlex® Bunion Correction Device?
Dr. Geldwert: For years, I saw patients delay treatment because traditional bunion surgery was simply too invasive and the recovery too painful. I wanted to create a solution that addressed the problem earlier and helped avoid those barriers. HyperFlex® was designed to correct bunions while preserving the natural anatomy of the foot, eliminating the need for bone cutting and allowing patients to recover much faster.
Q: How does HyperFlex® fundamentally change the patient experience?
Dr. Geldwert: It’s a completely different experience. The procedure can be done in about 20–30 minutes using a small incision, and patients can often walk the same day. Instead of weeks or months of immobility, we’re seeing patients return to normal activity within a few months. More importantly, we’re preserving motion and reducing trauma, which leads to better long-term outcomes.
Q: What makes HyperFlex® different from other “minimally invasive” procedures?
Dr. Geldwert: Many so-called minimally invasive techniques still involve drilling or altering the bone, which can lead to complications like fractures, stiffness, or prolonged discomfort. HyperFlex® avoids that entirely. It uses a flexible implant to realign the bones while keeping the foot’s natural structure intact.
Other minimally invasive techniques have longer recovery periods of many months, including several weeks of not being able to bear weight on the foot. HyperFlex® is a quick, 20-30 minute procedure that allows patients to walk out of the office same-day. Our recovery protocol encourages walking each day, and patients can experience full recovery in as little as 3 months.
Q: Your approach seems very patient-centric. How important is personalization in treatment?
Dr. Geldwert: Personalizing treatment is my focus. No two patients are the same; their anatomy, activity level, and goals all differ. My approach has always been to tailor treatment plans to the individual, not just the condition. That’s why I’ve invested in advanced diagnostics and innovative techniques that allow us to customize care, starting with a full-body exam to identify sources of pain and discomfort in the feet.
Q: That idea of personalization is also central to brands like Gainful. Do you see parallels?
Dr. Geldwert: I do. Gainful has built its model around personalized nutrition by creating supplements tailored to an individual’s body, goals, and lifestyle. That’s very similar to what we’re doing in podiatry and bunion correction.
In both cases, the shift is away from generic solutions and toward precision. People want solutions designed specifically for them, and when you deliver that, outcomes improve, because the solution actually fits the individual.
Q: HyperFlex® also enables earlier intervention. Why is that significant?
Dr. Geldwert: Traditionally, patients are told to “wait until it gets worse” before surgery becomes an option. That’s not ideal when bunion pain and discomfort disrupt your comfort and daily life. With HyperFlex®, we can treat bunions earlier and prevent progression. This not only reduces pain but also improves overall quality of life. Early intervention is one of the biggest advantages of this technology.
Q: What’s your vision for the future of HyperFlex®?
Dr. Geldwert: My goal is to make this approach more widely accessible so that patients don’t have to live with pain or delay treatment. We’ve already seen strong early results, and as adoption grows, I believe HyperFlex® can redefine the standard of care for bunions.
Dr. Geldwert’s work with HyperFlex® reflects a broader shift across industries toward personalization, efficiency, and better user outcomes. Much like Gainful’s tailored approach to nutrition, HyperFlex® demonstrates that when solutions are designed around the individual, the results can be transformative.
