I have had a chance to observe the use of US by my younger colleagues who are very adept with the technology while I have been doing in locums work. I would say that US can help reduce diagnostic uncertainty in regards to inflammatory arthritis including “undifferentiated arthritis”, crystal-induced arthritis, unexpected anatomy or pathology and challenging aspirations and injections of joints and soft tissue structures (carpal tunnel, tendons, bursa, etc). US is an additional tool that decreases uncertainty in a timely manner. While not a “game-changer”, US appears to be a very useful tool with both diagnostic and therapeutic applications that make our lives a little bit easier. It’s also fun to do with immediate gratification!
