In orthopedics, the term "nano" has become a buzzword, promising revolutionary changes at the smallest scales of material science. However, I talked with an expert, and the distinction between what's marketed as "nano" and what genuinely harnesses nanotechnology for orthopedic applications is vast and often misleading.
The Misuse of Nano
I was trained in orthopedics when researchers were trying to figure out optimal conditions for boney ingrowth into porous coatings. We asked this question decades ago, "What sized hole and what material with cancellous bone like to grow in to ?"
A nano expert starts by clarifying a common misconception. "Forget everything you think you know," he advises, emphasizing the scale difference between micro and nano. Nanotechnology operates at a scale of 10^-9 meters, a world apart from the microns 10^-6 meters, we're accustomed to dealing with in traditional orthopedic devices.
The misuse of the nano designation often involves slapping the term onto products without any genuine nanoscale manipulation or benefit. This mislabeling can mislead consumers, investors, and even clinicians into believing they're dealing with cutting-edge technology when, in real...
