This is an injury to the ulnar collateral ligament of the metacarpophalangeal joint.
The injury happens when you fall onto the outstretched thumb and is more likely if the thumb is gripping something at the same time…
Falling when skiing while holding a ski pole is a common cause hence the name frequently given to this injury – skier’s thumb. Less often there is no specific injury and the cause is due to a chronic stretching of the ligament. This is referred to as a ‘gamekeeper’s thumb’. In my case, I got ‘Cyclist’s Thumb’ as I’m calling it, where I fell slowly sideways off my bike, and all the weight of it (and my panniers) was taken on my left thumb which was hooked under the handlebar.
I had to go to hospital… resulting in a plaster cast from my elbow to mid-hand. ‘Bother’, I may have said.
I cancelled my flight booked to John O’Groats…
(Although I did recover and departed from Southampton for John O’Groats on the 5th September – one month later)
