These are the STL files for our adjustable pulley splints, which allow you to 3D print them yourself.
Pulley splints aid in pulley injury recovery, specifically for grade III (full rupture of the A2 or A4) and grade IVa (full rupture of the A2 + A3 or A3 + A4). These are NOT for pulley injury prevention.

🏅 Support the pulley without immobilizing the finger
☝️ Better fitment from the stepped adjustments
👌 No bruising on the back of your finger due to wide band and padding

Pulley splints/supports are meant for grade III-IVa pulley injuries (which involve one or more complete ruptures). They are unnecessary for more minor pulley injuries and should not be used for non-pulley-related pain or undiagnosed finger pain.
For grade IVb injuries (complete tear of A2, A3, and A4 pulleys), advice from a skilled medical practitioner is required and as such use of pulley support should be guided by them.
If you are unsure whether a pulley support is right for you, seek guidance from a qualified practitioner. You may also consider using our finger injury assessment toolto learn more about the different grades of pulley injury.

PCTG filament
Foam or silicone for padding (we recommend 3mm self-adhesive EVA foam padding)
1️⃣ To determine what size splint you need, simply use your US ring size. If you don’t know it, first measure the circumference of your finger: https://youtu.be/U6xW-hTZOCw?si=oHlgkjoYO2o1vbq6
2️⃣ For A4 pulley injuries, make sure you take the measurement at the A4 region (middle phalanx).
3️⃣ If you have swelling, you may need to purchase multiple sizes (e.g., one for your current level of swelling and one for your normal ring size without swelling). Use your uninjured hand for reference if you don’t know your non-swollen ring size.
4️⃣ Use the chart to find the closest US ring size to your measurement: https://tinyurl.com/yurrhfxt
NOTE: These splints have been sized in a way that accounts for 3mm of EVA foam padding on top for cushion. If you use a different type or thickness of padding, your ring size may no long equate to the correct splint size for you.
