Broad, curved dorsal center pad distributes pressure over a large area. Tension is adjustable by careful bending. Force: 15° flexion ≈ approx. 12 oz.; 90° flexion ≈ approx. 6 lbs.

Review: The best finger splint!!! - I use this finger splint on my middle finger of my right hand after having surgery for trigger finger. It works great!!! Easy to use. I wear it a great deal to straighten and stretch the tendon. Trying to straighten the tendon by pushing down on the finger yourself is painful. This device when set properly is painless. It gradually applies enough force to straighten the finger. I use it on and off all day long as I continually work to regain finger flexibility. This is the 6th surgery I’ve had (on different fingers). Recovery is going to take at least 4 to 6 months. This is the same product I have used each time.

## Questions & Answers

**Q: What are the dimensions of this item B?**
A: Three or four inches, roughly

**Q: is this the right size for pinky?**
A: These come in at least two sizes. Probably best if you get fitted by an o Occupational Therapist.

**Q: where is the measurement information to pick a size?**
A: If you look at the display on Amazon, right after the name of the product you will see "AA." That is the size. They range from AA to A to D. Here's what one purchaser wrote, based on language on the packaging when the product was delivered: I, "Measured from palmar crease to distal finger crease." specifically on my left pinky finger, did exactly as told to do, and got (give or take 1/16") 2 1/2"; wherein I purchased this size. After receiving the product and reading the packaging/instructions it clearly indicates that AA is 2 1/4" and A is 2 3/4"

**Q: What is the difference between size a and size aa? i need one for my little (pinky) finger**
A: I had the same question, so I bought both an A and an AA. For a pinky finger, especially for a woman, the A is too large. Get the AA. I returned the A.

### ⭐⭐⭐⭐⭐ Works great
*by A***R on October 23, 2025*

Works great in keeping pressure on the finger

### ⭐⭐⭐⭐⭐ It straightens finger.
*by D***O on February 18, 2024*

It is simple and it works. I jammed my finger in swimming accident. It does what it is suppose to. My finger eventually bends again when I take off, but it is straight sometimes up to an hour after taking off. Too early to tell if I will be cured, but if I don’t it won’t be because of this product. It fits right, is fairly comfortably and straihtens my finger
