3pp Ez FIT Thumb Spica Splint Ultra Light Immobilization for De Quervain's, Gamekeepers Thumb & Thumb Injuries, One Size Fits All

This splint is great for treating De Quervain's tenosynovitis where you need to stabilize the side of your thumb knuckle all the way down to your wrist to rest your inflamed tendons and alleviate discomfort/pain from movement.I've been wearing it for a month straight to treat De Quervain's tenosynovitis. I love the lightweight and slim design because I am still able to use the rest of my hand with exception to my thumb because that's what needs stabilizing to heal. You don't get this much mobility when wearing a regular splint because it stabilizes your entire wrist, palm, and you lose some of the mobility with your fingers. With this splint, I am still able to do most things, such as type on a keyboard, use a mouse, put away dishes, fold laundry, etc. with this splint!The material is very soft and sturdy. I only take this splint off when I shower or wash the dishes and have never felt my skin be irritated. Sleeping in it is also comfortable; it doesn't wake me up at all! Just don't tighten the straps too tight or your skin will become irritated. The boning to stabilize the side of your thumb down to your wrist is very sturdy and has not become flimsy or deformed whatsoever in the 1 month I've been wearing it.A couple critiques:(1) The velcro strip for the thumb is very long, so I had to cut it shorter to suit my small thumb, so your mileage may vary depending on the size of your hands. It may be intentional to suit different hand sizes, so you can cut it down to the proper length for your thumb circumference.(2) The middle wrist strap's velcro gets caught on things the most because it stops at the side of my wrist so it gets caught on things sometimes and becomes undone.(3) I've noticed that over the 1 month period I've been wearing this, the velcro "teeth" for the middle wrist strap have become bent and are not as strong anymore, thus prone to catching on things and coming undone. For what it's worth, the other two straps (thumb and lower wrist straps) have never become undone or gotten caught on anything.Overall, this is a great splint and worth every penny.

works great. bought two different splints and this one feels the best.

With sudden onset De Quervain's tendonitis. I wanted something to mostly immobilize my wrist without undue bulk or interference with activities like knitting, and after researching many options chose this one for its open, lightweight design. For the first few weeks of wearing it around most of the day and every night, it did seem to help alleviate pain and swelling. After a while it got a little grubby with nonstop wearing and I started getting contact dermatitis (little itchy red bumps) under it, which I solved by cutting the sleeve off an old shirt and wearing that under the brace. (I handwashed the brace after I stopped wearing it every day, which worked fine, but it took a couple days to fully air dry.)Pet hair, loose threads, and so on are attracted to the strap fabric and I found myself needing to use a lint roller on it frequently. By week four the velcro was starting to lose its stick, but by then I was also realizing that the one-size-fits-all design wasn't working very well—the brace was really too big for my arm, not so much in circumference (the straps do tighten sufficiently on my 6 in. wrist, although that's about their lower limit) as in length: my arm is 4 in. from thumb webbing to wrist and ~9 in. from wrist to elbow, and when the thumb loop is properly seated on the thumb webbing, the wrist strap rubs painfully on the inflamed bump of my wrist. And when the wrist strap is positioned properly closer to my hand, the thumb strap is at the top thumb joint and impedes thumb motion. It tends to slide up and down too, unless I overtighten the straps.The metal tongue that stiffens the brace CAN be bent as needed for positioning, but not easily, and in my experience not with only one good hand. Best to get a strong friend with two good hands to help with that bit.After a while the brace seemed to be making matters worse rather than better, so I stopped wearing it when I realized that for most activities I feel less stiffness and pain with more freedom of motion. Oh, well—it was an experiment that served its purpose, if with mixed success as to alleviating pain. I do still occasionally wear it for nighttime stabilization (to keep from twisting my wrist in my sleep), and it's more satisfactory for that purpose than when I'm actually using the arm.

if you need a hand splint, there's a lot to love about this hand splint. Let's start with comfort. It's lightweight, provides serious support, and size-adjustable. It can even go on both the left and right hands which is cool. I've worn custom made splints and bought over-the-counter splints for the past 20 years. This is my favorite of all the over-the-counter hand splints. On top of that, it goes in the pool with me and dries rapidly.

Excellent, prevents motion but no hot spots, can wear it all the time, even while washing hands a lot of the time, excellent design. Left hand can use computer keyboard without issue.44 days in, durability for the velcro is showing some signs of weakness but it hasn't yet affected the product staying on, I sleep with it on, etc. I do accidentally snag it several times when putting on a jacket so be careful of that.**Update 3-4 months in... it can still stay attached but it tends to come undone and flop around and attach somewhere else on the brace. It's clearly not the material loses it's ability to hold the hooks, since the hooks work on fresh areas or attach to other items I own, so the plastic hooks are not the issue on the adhesion. Durability problem it seems, unavoidable. This is a problem but it works very well. So it's kind of an odd spot to put it rating wise. Maybe closer to a 4 but since reliability being a problem, that's should be a big hit so 3.5-3.75 sounds right unless there's an easy remedy to this.Replacing the velcro requires sewing or gluing it seems like, using AI to brainstorm solutions. I guess I could just use medical tape too lol
