Scientists have developed a special zinc-based dissolvable material that can be used to fix broken bones in place of metal plates and screws.
According to a study published on 12 February, the materials designed by Monash University’s biomedical engineers are mechanically strong but gentle enough to degrade safely over time while supporting optimal healing.
A game changer for orthopedics
Before now, orthopedic surgeons relied on stainless steel or titanium to fix bone fractures. However, these materials stay in the body forever, can cause discomfort and may require follow-up surgeries.
The zinc alloys are as strong as permanent steel implants and more durable than other biodegradable options like magnesium-based implants, making them perfect for fracture treatments.
Lead researcher, Professor Jian-feng Nie, from the Department of Materials Science and Engineering, said this sustainable option can transform orthopaedic care by reducing complications, minimising the need for additional surgeries.
“An implant that never disappears will always be a risk to the patient. On the other hand, one that degrades too fast won’t allow adequate time for the bones to heal. With our zinc alloy material, we can achieve the optimal balance between strength and controlled degradation of the implant to promote better healing.”
The zinc alloy can bend and adapt in unique ways to accommodate the shapes of its neighbouring tissues, making it safe for use.
Based on the success of this research, Monash University is considering establishing a new start-up to focus on developing next-generation biodegradable implants for better orthopedic care in the future.
Advances in science
Scientists have come a long way in developing means by which medicine and medical care can advance.
Another groundbreaking study is being planned at Oxford University that requires growing human brain cells in the lab for studying Parkinson’s Disease as well as other neurological disorders.
