University of Central Florida (UCF) researchers are driving the future of healthcare with the advancement of bioabsorbable implants. Breaking away from the norm of traditional titanium bone implants, UCF’s Biomedical Engineer, Mehdi Razavi, is pioneering a novel method for healing bone damage that eliminates the need for additional surgeries.
The Challenge of Metal Implants
Traditional titanium bone implants, despite their long-standing use in medical practice, present challenging repercussions for patients, especially children. Surgery involving metal implants often necessitates a second procedure to remove them. This can be stressful and carry psychological implications for patients, especially considering that one in three children breaks a bone at some point in childhood, as noted by pediatric orthopedic and sports medicine surgeon, Zach Stinson from Nemours Children’s Health.
Bioabsorbable Implants Resolve Issues
Razavi and his team are turning to magnesium for an innovative solution. As Razavi explains, “Magnesium has mechanical properties very similar to bone. It already exists in the body and promotes bone formation, making it an ideal option.” These bioabsorbable magnesium composites being developed by Razavi’s team, promise a revolution in the field of medicine, as they are designed to naturally dissolve within the body, eliminating the need altogether for additional surgeries.
These groundbreaking magnesium implants also harbor nanoparticles that facilitate the regeneration of new bone tissue, thus significantly quickening the healing process. Razavi remarks, “What we do is called regenerative medicine, where we build bioactive materials that can repair tissue.” His research converges advancements in material science and medicine, focusing primarily on the recovery of bone tissue lost due to fractures, tumor removal, and osteoporosis.
Potential to Transform Healthcare
Second-year UCF medical student, Alison Grise, a crucial contributor to this pioneering research, speaks passionately about her involvement, “It is so exciting to be working on research that can eventually improve the way we treat patients, especially to be involved in the early stages. The fact that it is helping me build my surgical, clinical and research skills is also noteworthy.”
These groundbreaking magnesium implants dissolve within three to six months post-surgery and are safely filtered out by the patients’ systems. Early testing in rat models paints a promising picture for the potential implementation of this innovation in human patients.
The potential of this research extends beyond medicine as well. Razavi’s team has received funding from the U.S. National Science Foundation to refine the properties of the magnesium composite for potential applications in the automotive, aerospace, and sports industries.
The ground-breaking work on bioabsorbable implants done by the Razavi-led UCF team represents a monumental stride forward in healthcare and regenerative medicine. Offering both psychological relief to patients and cost-saving benefits to the healthcare industry, the future of bone healing is indeed exciting and looks set to revolutionize how we approach bone damage today.
