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 ?"
