CMC Thumb Arthritis
CMC THUMB ARTHRITIS
Arthritis occurs when the cartilage – the flexible tissue that covers and protects the joints - wears out. Without this cushioning, the bones in the joint grind together wearing the joint down. Carpometacarpal (CMC) joint arthritis is arthritis at the base of your thumb, where your thumb and wrist meet. As the cartilage wears down, the ends of the bones rub together causing pain and making it difficult to use your thumb.
Named for the bones that make up the base joint of the thumb – a Carpal (wrist) bone and a Metacarpal or long bone of the thumb – the (CMC) joint is the most common place in the hand for arthritis. CMC joint arthritis can be mild or it can progress over time, and it is best to treat it early with some simple measures.
Pain at the base of your thumb
Pain when you pinch or grip small objects, pens or keys
Pain or tenderness when you press on or around the joint
What Can I Do About It?
a splint or brace that helps support your thumb is one way to reduce pain and
lessen the effects of arthritis on your thumb. Thumb splints offer different
levels of support depending on the way they are made. Flexible fabric splints provide compression and support for
stability, while splints with metal strips
help hold the thumb in place to allow it to rest. Choosing the right splint
is key to properly manage your CMC joint arthritis.
