As the prevalence of diabetes rises, more people will face the complications of diabetes, including lower extremity amputation. However, there may be a ray of hope in the form of a recent study in PLOS One that notes a significant reduction in amputation rates among patients with diabetes in Italy.1 Read More.

Although three-dimensional printing technology is an emerging solution for a number of real world problems, there has not been much research into the viability of 3D printing of surgical instruments. However, my colleagues and I recently conducted a study in the Journal of Surgical Research showing that 3D printers can produce durable, sterile surgical instruments at a cost of about 10 percent of the price of stainless steel OR tools.1 Read More.

For patients with diabetic polyneuropathy, plantar foot ulcers can develop due to higher plantar pressures. Is muscle strengthening the answer to relieving such pressures? The results of a new study in the Journal of Foot and Ankle Research cast some doubt on this question, which many have had for some years.1 Read More.

At the University of Arizona Medical Center, we are recruiting patients for two studies, among many others, that may have the potential to lead to improved healing of wounds and diabetic foot ulcers. The first study involves a spray-on skin solution. The technology works in a similar way to bioengineered tissues. The big difference is that because it has a spray-on quality, the skin solution can go over a larger surface area and perhaps the contact with wounds and delivery may be better than previous iterations.

Although diabetes takes a costly toll, literally and figuratively, on the foot and ankle, there is a stunning gap in lower extremity diabetes research funding.1 Our recent study, published in Diabetes Care, examined U.S. National Institutes of Health funding for diabetes and diabetic foot ulcers. Our research revealed total spending of $7.1 billion in funding for overall diabetes research from 2002 to 2011 with only $11.8 million, or 0.17 percent, reserved for research on diabetic foot ulcers. As we note in the study, this is a 604-fold disparity. Read More.
