While you may be able to find braces that are specifically designed to treat trigger finger injuries, any basic finger brace or strap will do. The goal of a trigger finger brace is to keep the finger straight and ensure it doesn’t bend, while also preventing excessive movement that can intensify the pain.
Frog finger splints are a good, affordable finger brace option. They are lined with malleable aluminum and padded with foam to provide comfort and support simultaneously.
