This is Scientific American's 60-Second Science. I'm Steve Mirsky. Got a minute?
You've heard of tennis elbow. Well, a friend of mine has gamekeeper's thumb. When he told me his diagnosis1, it rang a bell. So I went through the Scientific American archives. And found this:
"Injury to the ulnar collateral2 ligament of the metacarpophalangeal joint3 trips off the tongue more agreeably as gamekeeper's thumb. The name comes from the chronic4 ligament damage incurred5 by Scottish gamekeepers in the course of killing6 wounded rabbits."
The article that comes from quotes a physician named Kevin Math, that's right, Dr. Math, who explained, "The gamekeepers would grasp the hare's neck between the base of the thumb and index finger, and repetitively twist and hyperextend the neck. The activity would have to be repeated thousands of times before the ligament would get stressed to that degree." Talk about curling your hare.
The same thumb damage can result during a fall while skiing, from the torque of the pole strap7. Doctors still refer to gamekeeper's thumb more than skier's thumb, even though schussers presumably outnumber bunny snuffers these days. My buddy8 was injured playing softball. So I'm happy to report that no animals were harmed in the making of his condition. For which we give him two thumbs up.
Thanks for the minute. For Scientific American's 60-Second Science, I'm Steve Mirsky.
