Nail bed injuries are common from finger trauma, but we can't be just ripping off everybody's finger nail to see what what was injured. Maybe ultrasound can help? Hey maybe we also can find fractures of the finger tip while we're at it. This paper takes a look to see how accurate ultrasound is in the diagnosis of these injuries! Honestly, most people are probably not removing finger nails just to repair a small laceration these days so you will have to decide for yourself how this might be useful to you.
