CMCcare Thumb Brace: Fitting & Adjustment Videos - Oct 2026

The CMCcare Thumb Brace stabilizes the carpometacarpal (CMC) joint to help reduce pain from CMC thumb arthritis, also known as basal joint arthritis. Its functional design leaves the ulnar side of the hand free to support everyday hand use.

Features That Support Fit and Comfort

Features of the CMCcare include:

• Smooth, contoured edges help reduce pressure around the thumb and web space. A 3pp Cozy Liner or Gel Mate® silicone gel provides added cushioning.
• An adjustable aluminum stay conforms around the CMC joint with a simple squeeze.
• A removable, replaceable strap adjusts at both ends for a comfortable, supportive fit.

The careful design of the CMCcare Thumb Brace eliminates the need to make any significant adjustments. When needed, the edges can be flared using a spot heat gun.
