How a CMC Arthritis Brace Works

November 4, 2015

CMC Brace IV

CMC Arthritis is a common problem.  According to a recent study, CMC OA is 3-4 times more likely in women than in men.  Between 1998 and 2012, 1 in 20 women (seniors) had sought treatment for CMC Arthritis.  A small joint can cause a lot of pain.

As arthritis develops in the CMC joint, the thumb takes on a classic posture of deformity.  A bump will slowly develop at the base of the thumb as the CMC joints becomes lax and less tightly seated.  Bone spurs can appear.  When the MP joint collapses the thumb will hyper-extend.

The goal of splinting for CMC arthritis is to reverse the predictable postural deformity of the thumb; seating the CMC joint, lifting the metacarpal head, and opening the web space.  The new CMC Thumb Arthritis Brace is an effective alternative for treating thumb pain and increasing function.  It is easy to use and low-profile.
