Thumb Strapping Guide Poster
A jammed thumb on a netball court, a footballer's hand caught the wrong way in a tackle, a basketballer's thumb bent back against the ball. Sports clubs and school PE staff see thumb injuries every week, and most of them are not serious enough for a hospital, but too sore to play on without support. The right strap can get a player back on the field, protect a healing thumb, and stop a small sprain becoming a bigger one.
This guide walks through how to strap a thumb properly, what tape to use, and when to send the player to a doctor instead of taping them up. The four-step method shown below is the same one printed on our downloadable poster lower down the page.
When to strap a thumb
The most common reason for thumb strapping is a sprain to the ligament at the base of the thumb, the ulnar collateral ligament. In ball sports this often happens when the thumb is forced backwards or outwards, away from the hand. In skiing it is the same injury caused by a fall with the ski pole still in the hand, which is why it is sometimes called skier's thumb.
You would also strap a thumb after a jammed thumb at the joint, where the player has full movement but the joint is tender and sore. A well-applied strap takes load off the injured ligament so the player can grip, catch and tackle without making the injury worse.
Do not strap a thumb that looks deformed, will not move at all, or is numb at the tip. Those are signs of something more than a sprain, and the player needs a doctor, not a tape job.
What you need
A basic thumb strap kit is small and cheap to keep in any sports first aid bag. You need:
- A roll of 25mm stretch elastic adhesive bandage tape, usually shortened to EAB. EAB is the beige, slightly stretchy strapping tape that makes up the main wrap. The stretch lets you build support without cutting off circulation when the player warms up.
- A roll of 25mm rigid sports tape. The white, non-stretch tape, used at the end to lock the EAB wrap in place.
- A pair of small sharp scissors. Blunt scissors mean a slow tape job and a frustrated player.
- A clean, dry hand. Wipe sweat off with a towel before you start.
Sports clubs working through bulk strapping for a season usually find it cheaper to buy stretch EAB tape and rigid strapping tape by the carton rather than single rolls. Our Straptor genuine sports tape is the format clubs reorder year on year. The same goes for stocking a club bag with the rest of the on-field essentials, which is what our sports first aid kits are built around.
How to strap a thumb, step by step
The technique below is the four-step thumb taping method shown on the FAD thumb taping poster, prepared with the advice of a registered physiotherapist. It anchors the wrist, builds figure-8 wraps around the thumb, and locks off with rigid tape. The whole thing takes about a minute once you have done a few. The same steps are shown with photos in the printable poster further down the page.
Step 1. Wrist anchor with EAB. Using 25mm stretch EAB tape, loop the tape around the wrist just above the wrist bone. Direction matters: go clockwise on the left wrist and anti-clockwise on the right wrist, so the figure-8s in the next step pull the thumb in the right direction.
Step 2. Figure-8 around the thumb. From the wrist anchor, run the EAB up over the back of the hand, around the proximal joint of the thumb (the knuckle at the base of the thumb), and back down to the wrist. Be careful not to pull this tight. Too much tension here will cut off circulation and sensation. After the figure-8, take another loop around the wrist to bed the wrap in.
Step 3. Repeat the figure-8. Repeat step 2 up to three times, each figure-8 sitting just over the top of the last one, until the thumb feels stable. More figure-8s give more support, but more is not always better. Stop when the player feels solid, not when the tape runs out.
Step 4. Lock off with rigid tape. Run a strip of 25mm rigid sports tape around the wrist, over the top of the EAB anchor. This locks the whole wrap in place so it does not unravel during play.
Final check. Before the player goes back on, ask them to make a fist, open the hand, then move the thumb gently. The strap should restrict the thumb from being pulled outwards, but the rest of the hand should move freely. Check the fingertip and thumbnail are still a healthy pink, not white or blue. If the fingertip looks pale or the player says it feels tingly, the wrap is too tight. Take it off and start again.
Common mistakes
A few small mistakes turn a useful strap into a useless one, or worse, an unsafe one.
The first is pulling the figure-8 too tight on step 2. EAB has some give, but a tight figure-8 around the thumb knuckle will cut off circulation as soon as the player warms up and their hand swells slightly. The finger and thumb tip should stay warm, pink and feel normal.
The second is skipping the rigid lock-off in step 4. The EAB wrap on its own will peel and unravel within minutes of the player starting to run. The rigid tape around the wrist is what holds the whole thing together for an entire game.
The third is going the wrong way around the wrist. Clockwise on the left wrist, anti-clockwise on the right. Getting this backwards means the figure-8s pull against the thumb's natural movement rather than supporting it.
The last is strapping over a bare, sweaty hand without thinking about the skin. For a once-off, the tape comes off fine. For a player who is taping every training session and every game, build a layer of underwrap first or you will pull skin off with the tape at the end of the season.
When to send the player to a doctor
Strapping is for sprains and jams that will heal in a few weeks. Send the player to a GP or an emergency department, not back on the field, if any of these are true:
- The thumb looks crooked, bent at the wrong angle, or sits oddly compared to the other thumb.
- The player cannot move the thumb at all, or cannot pinch finger and thumb together.
- There is bruising that spreads up the wrist or into the palm within an hour.
- The thumb is numb, cold, or pale at the tip even before strapping.
- The pain is severe and not settling, or the player heard a snap or pop at the time of injury.
Any of those point to a fracture, a complete ligament tear, or a circulation problem. Tape will not fix those, and putting a player back on the field with one of those underneath is how a six-week injury turns into a six-month one.
For the run-of-the-mill sprains and jams you see on a club sideline, strapping is enough. For anything beyond that, get the player off the field and a medical opinion before doing anything else.

Sports Medicine Australia and the Australian Physiotherapy Association both publish further reading for clubs and coaches if you want to read more on sports tape, sprain management, and return-to-play decisions.
If your club or school is restocking strapping tape, stretch EAB tape and rigid strapping tape are the two formats you need for thumb taping. We supply schools, sports clubs and community organisations across Australia and we can put together a regular restock so you are not chasing tape mid-season.
