CMC Arthritis Brace

August 25, 2015

Historically basal joint arthritis or CMC arthritis has been treated with thumb splints that immobilizes the entire thumb.  In many cases these thumb braces extend down past the wrist.  These are big, bulky thumb splints whose primary purpose is to immobilize.

The Push brace Metagrip is a new alternative to treat CMC arthritis.  This is a low-profile and light weight design that utilizes dynamic stabilization.  During pinching when the CMC joint is being loaded, there is generally ligamentous laxity which allows the first metacarpal to move around.  This movement is what creates the thumb pain.  This CMC Arthritis Brace prevents that movement by stabilizing the CMC joint, not immobilizing it.

The Push Brace is made from pliable thermoplastic and is constructed with a moldable aluminum insert.  When the brace is first applied the insert needs to be squeezed around the thumb – that is the key to the brace.  Once applied the brace needs to be “broken in” like a new pair of shoes.  It may feel stiff at first but after the brace is worn for a while it will fit better.

This thumb splint is low profile enough that tasks which are difficult in a standard wrist and thumb brace can be easily accomplished:  play a musical instrument, drive a car, wear gloves, reach into your pocket….
