This is the 2nd time I have experienced this injury (2nd time being more severe with the fracture). The splint provided by my doctor was a similar style, but was harder plastic & did not have the split top that this one has, so there was a slight gap between my finger and the splint. Features I love about this splint (there are a lot): protects the finger and keeps the top joint immobilized, has a split top so as the swelling in the finger changes you can adjust and keep the fit snug, the Velcro removes the need to have sports tape around, the material of the plastic decreases the "gym foot" smell that can occur with a splint, it is less noticeable in day-to-day activities – both from my perspective and to others (don't have to constantly answer what happened to your finger), and finally there are two in the package so you can rotate to clean and not be without splint at any time.
Another option I have seen recommended for a mallet finger is the "figure 8" type splint; there is simply no way this splint could provide the protection you need with a mallet fracture. You would be shocked at the amount of times you bump your finger on things throughout the day & the figure 8 splint will not protect your healing finger from these encounters.
This may actually be the first Amazon review I have written, but I am so pleased with this product that I felt the need to let others know how tremendous it can be in the healing process. A mallet finger can take anywhere from 4-8 weeks to heal, depending on the severity, so you really want to have a splint you are comfortable with and I give the Thinvik splint my 100% seal of approval.

Seems to be working. On week 2 and holding finger upwards. Able to use hand as it does not restrict the lower knuckle. I used moleskin on inside and wrapped with tape to make sure it stays on which makes it harder to breathe though. I ordered a second one so I can start changing it out.

Let me start out by saying this product is the same high quality product they use at the specialists office. The one problem I encountered was that the splint is cut down the middle to adjust to various finger sizes. The issue that arose was the overlapping plastic rubbed and irritated the skin. It performed well but caused skin irritation underneath. I eventually had to go get a replacement from my primary care physician.

I tore my pinky ligament and went to see about 4 doctors because my finger tip was drooping and would not go back up after having a tub of yogurt fall on my finger. They took x-rays and I was told i had Mallet finger. They sent me to a physical therapist office to cast my finger. I was told not to buy a splint that they were going to put a professional cast/splint on my finger. The lady took a piece of plastic board cut it warmed it up to slightly melt to fit my finger then put tape on it. It didn’t look professionally done at all, it did not fit my finger properly and it look like my 6 year old granddaughter could have made it for me and it was very uncomfortable. With that said i left it on for 4 weeks and it felt like my finger was getting worst. I had no pain with the initial accident but weeks later i was feeling alot of pain, i finally went online did some research and found this little finger splint and immediately putting it on I was in complete comfort. It came in 3 sizes but one of them fit my finger so perfectly as if it was made for me. I have really thin fingers, i wear a size 4 on my ring finger which is pretty small so my pinky is probably a 2 or 3
Its my first time wearing it but so far so good thank you i love it. The doctors were a waste of time and money!! Their in the business of making money not healing. Im pretty sure they did a crummy job so that i can come back for physical therapy.
Urgent care had me go to the hospital for X-rays ,then they had me go to another doctor to look at the x-rays, then they had another doctor put the crummy splint i wasn’t sure why one doctor couldn’t do everything in one facility i was billed 4 $40 copays completely ridiculous never again. Lesson learned
