I am a snowboarder, and I've had a couple of painful ankle sprains. Should I do something about it?
Absolutely. What feels like a series of ankle sprains could actually be a break in the main ankle bone, called the talus. The fracture commonly involves a small bump on the outside of the talus. This kind of injury is common among snowboarders but hard to see on an average X-ray. Doctors can identify ankle fractures by X-raying the ankle at a specific angle and by using a CAT scan. The CAT scan provides a detailed X-ray that looks like "slices" of the bone tissue.
