The Stax Mallet Finger Splint is ideally suited for the repair of a ruptured tendon. They are designed to support the distal joint of the finger in extension while permitting unrestricted movement of the proximal interphalangeal joint.
The Splint is normally used without padding and is fixed to the middle phalanx with a small strip of adhesive tape, thus automatically elevating the distal joint to its proper extended position.
Occasionally, the dorsum (back) of the finger may be too tender to tolerate a normal size Stack Splint. A much larger size, padded on the inside, should be used until the swelling has subsided enough to replace it with a Splint of the proper size. Because they are made of lightweight, flesh-coloured plastic, patients will find Stack Finger Splints comfortable to wear for long periods of time.

Sizing Chart
Important Note…When measuring your finger, measure very loosely. If your measuring tape is too tight around your finger, the splint may not fit. Measure around the distal interphalangeal joint (the 1st joint on your finger closet to the tip of your finger). We always recommend going one size larger unless you have used these before and know your size.
| Size | circumference of DIP (distal interphalangeal joint) in cm |
| 1 | 5cm or less |
| 2 | 5cm to 5.5cm |
| 3 | 5.5cm to 5.8cm |
| 4 | 5.8cm to 6.3cm |
| 5 | 6.3cm to 6.8cm |
| 5.5 | 6.8cm to 7.1cm |
| 6 | 7.1cm to 7.3cm |
| 7 | 7.3cm to 8.4cm |
 | Measurement: Measure loosely around your finger joint at the DIP Joint (see arrow for location) in cm. |

Perfect. Much better than my home made splint

Mangled up my finger during COVID. I use the Oval 8 during the day as it gives me a little more latitude and movement. I have been swapping it at night with the Stax finger splint. Glad I found these items.

This is way too big, so I likely didn’t measure properly and also thought I had a fractured finger, but now arthritis has set in.

This is a very practical and easy to use splint for a mallet injury. It allows almost full normal use of the hand during the healing process. I found it more comfortable though, after enlarging the air holes with a drill press, as it tends to get somewhat damp inside with activity. I’m happy that I bought 2 sizes, one to fit on the swollen finger for the first week or so, and a size smaller for the remaining 5 weeks.

I measured per the instructions and they were still too small and I can’t use them

Worked great…fracture is healed.
