Thumb arthritis pain can be debilitating, making everyday self-care tasks intolerable. There is a surgical option when other treatments, such as injections and therapy, fail to adequately reduce pain. A carpometacarpal arthroplasty or CMC arthroplasty is a joint replacement procedure for the base of your thumb.
Most activities that involve grasping or pinching are possible because of the thumb's remarkable range of motion. But dexterity comes at a price — an increased risk of osteoarthritis in the first carpometacarpal CMC joint, where the thumb meets the trapezium bone in the wrist. Sometimes the joint becomes so damaged that surgery is necessary.

We can help the majority of patients with thumb arthritis without the need for invasive surgery. So rather than moving on to the next step in our care paradigm which is stem cells, I told her I would look at the surgical options being offered to her and write a blog about her choices. First, almost all patients I have ever met who are offered surgery believe that since surgery is commonly performed for things like arthritis that there must be great research showing it works.
There are different recovery approaches, and every surgeon follows their own method. In order to avoid excessive swelling, it is necessary to keep the hand elevated for at least two days. While walking, do not leave your hand dangling at the sides, and do not rest it on your lap while you are seated.
During a physical exam, your doctor will ask about your symptoms and look for noticeable swelling or lumps on your joints. Your doctor might hold your joint while moving your thumb, with pressure, against your wrist bone. If this movement produces a grinding sound, or causes pain or a gritty feeling, the cartilage has likely worn down, and the bones are rubbing against each other.
Arthritis around the base of the thumb is a very common complaint. This is usually due to normal wear and tear, caused by the demands placed on the thumb during our everyday activities. Arthritis can cause pain, stiffness and deformity in the thumb.
A joint is formed when two bones meet and articulate, which allows movement. Joints are lined with smooth cartilage that allows for the easy movement of one bone relative to another. Osteoarthritisor degenerative arthritis, is a process that occurs with aging and describes the deterioration of the joint cartilage.
The carpometacarpal joint is where the metacarpal bone of the thumb attaches to the trapezium bone of the wrist. This joint has a very unique shape that permits the thumb to move in multiple directions. Arthritis at the CMC joint may cause changes in the shape of the joint and weakening of its ligamentous supports as well as the formation of bone spurs. Diagnosis is based on history, physical examination and X-Rays.
