Frequently Asked Questions
What is rhizarthrosis?
Rhizarthrosis, or thumb osteoarthritis, is the wear of the cartilage in the joint at the base of the thumb near the wrist (trapeziometacarpal joint). This irreversible damage causes pain and gradually reduces the ability to perform daily activities. In advanced cases, thumb deformity may occur.
Can you wear a thumb splint during the day?
The EPITACT® thumb splint for rhizarthrosis is specially designed to relieve you at night, during rest periods, and inflammatory flare-ups. Wearing this type of semi-rigid orthosis immobilizes the joint; therefore, it is not compatible with daily activities. That is why EPITACT® also created a flexible orthosis that relieves pain during the day while preserving hand mobility.
How to choose the right size?
Using a measuring tape, measure the circumference of your hand just at the base of the four fingers (do not include the thumb). Then refer to the size guide below.
