So what should you do if you get skier’s thumb. First of all do not move it. If you stretch an already damaged ligament you could convert a simple sprain (that would have healed up with a thumb splint) into a complete rupture that requires an operation. Similarly, you could convert a fracture that would heal up in a cast to one that requires surgery. Skiers often say that there can't be a fracture because: "I can still move my thumb." This is so not true. An X-ray will reveal all.

People often do not realise the importance of thumb injuries, and it is not uncommon for them to leave it until the next day before seeing the doctor. They are then amazed when they require an X-ray and an emergency referral to hospital for what they thought was an insignificant injury. Don’t fall into the same trap !

... THE SKI INSTRUCTOR'S VIEW ...

If you learn to ski with a qualified instructor at a good ski school - and there's plenty of them - you will be thoroughly taught all the basics, including the right way to hold your ski poles. Once you are able to ski 'on your own', it's up to you to remember the dos and don'ts your instructor taught you.

In some ways, learning to ski is like learning to drive: you need some intensive instruction to set you up for a lifetime on snow or on the road. Just like some drivers, however, skiers also tend to develop bad habits over time and a wrong grip on a ski pole may become the default - until it is too late. The real danger, however, is learning to ski from a perhaps experienced and well-meaning skier - but one who is not a qualified instructor. Like driving, skiing is a generally safe activity for those who have been taught properly.

I agree with MPI's observations on the correct way to hold ski poles and Alan Griffiths's warning.

... AND THE INSURANCE IMPLICATIONS

Do you hold your ski poles correctly, so the poles will simply stay attached to you if you fall? Or are you one of those people whose thumbs are in danger when skiers take a tumble?

It’s said anecdotally that incorrect positioning of the strap around your wrist when holding the ski pole is a national trait – and the British are allegedly among the worst offenders. We’re not taking sides on this, because it would be near-impossible to prove, either way – but we understand it is a common problem with all nationalities.

The simple answer is to make sure that you arrange your pole straps carefully. However, if you are skiing through the woods or where there is danger of avalanche, you should always remove the straps. And even if you are fully insured, it’s still worth remembering the old proverb: Prevention is better than cure!
