Dr. Robert Whitfield removes embedded turf rubber fragments from an athlete's foot. The body walls off the foreign material like a splinter, causing localized reaction. He demonstrates the extraction technique and tools used in podiatric practice.
These got embedded in the athlete's foot, and now we're just taking them out. It's healed in there. It's kind of like getting a splinter stuck, so your body will automatically try to wall this stuff off because it's not your own tissues, it's just foreign. So we've already numbed his foot, that's why this is something we can do.
