Best thumb splint i can find

I am suffering De Quervain’s Tenosynovitis, this is the BEST thumb brace i can find amount major Chemist around Sydney. Mind you that this is a SPLINT, it has a solid plastic embedded into the side to brace your thumb rigidly and wraps around so protect it from impact, highly recommended.

Thumb brace

Eases the pain and not cumbersome

Doesn't Fit

Says one size fits all... it doesn't. And you can only test the fit by opening the package ,which then means you can't return it. Complete waste of money.

Didn’t fit

One size fits all yet didn’t feel like it fitted correctly. Thumb didn’t feel supported

Strong 700 thumb

Son hurt his thumb at rugby - this little support has been great. One size fits all ( he's 12 ) It also does left or right hand - good happy with it

exactly what i needed and wanted

looked online at a few different places for a firm thumb brace after finding out I have osteoarthritis in my left thumb. Though this does not cure the problem it does help a great deal with support and it does help by restricting your thumb from too much movement. Its so good that I am going to order another couple


selasa bila pakai n kurangkan sakit

Perfect for Tenosynovitis (De Quervain’s Syndrome)

I needed a splint for this condition and this fits well. The base of the thumb & part of the wrist is well supported. Looking at the photo I thought I’d want more wrist support but this is perfect. It still allows for plenty of activity. I’ve only worn it for 2 days and already I feel an improvement along with the exercises for this condition.

Injured my thumb and got one of these. It does a really good job in keeping the thumb stable and immobile. But it starts to get really warm very quickly, my wrist gets itchy due to the mesh on the inside.

Hi Rico.,

Thank you for your review on our Strong 700 Men's/Women's Left/Right Thumb Support - Black!

We're sorry this item did not meet your expectations.

I'll bring your feedback back to our design team to see how we can improve the fabric in our future designs.

Thank you & sport on safely! :)

Good and affordable brace

Definitely helped support my thumb and wrist. Sturdy and solid.

Why wear this thumb strap?

Wearing this thumb support may be recommended if you have suffered major ligament damage or you are unsure how your thumb will hold up when you get back into sport (basketball, football, handball, tennis, running, trail running, gymnastics, judo) after a sprain. It can also be useful for people with osteoarthritis. The strap makes it easy to put on, while its foam padding and shaped stiffener keep you comfortable.

What is a sprain?

A sprained thumb is when the ligaments become stretched or torn. It tends to happen when people lose their balance on slippery ground and land on their hands, or when they misjudge a catch when playing handball, basketball, volleyball or any other ball sport.
