Thumb Arthritis

What is Thumb Arthritis? 

A joint is where bones connect and move. Arthritis is thinning of the cartilage, which is the smooth covering of the joint. The body reacts to loss of the joint surface by forming bone spurs (osteophytes). Arthritis at the base of the thumb is a genetic predisposition: like graying and thinning of the hair, it comes with age and it shows up earlier in some families. Unlike thinning of the hair, women tend to get arthritis in the thumbs sooner than men do.

 

Thumb Arthritis Symptoms

Patients with arthritis of the base of the thumb report pain and weakness with pinching and grasping. For instance, opening jars, turning door knobs or keys, and writing are often painful.

 

Thumb Arthritis Diagnosis

The diagnosis of thumb arthritis is made by talking with you and examining you. The appearance of the thumb can change with the development of bone spurs and stretching of soft tissues (ligaments). A grinding sensation may also be present at the joint. X-rays are not necessary to make the diagnosis, but they can help you understand the disease and they can help when surgery is being considered.

 

Thumb Arthritis Treatment

As with other aspects of aging, we adapt to thumb arthritis and treatment is often unnecessary. Options for treatment include non-surgical methods and surgery. Treatments without surgery range from ice/heat, pain medicines, splinting, and injections. Thumb arthritis surgery consists of removing the joint either by removing a bone or connecting the bones together. There are options for moving one of your tendons to secure or cushion the bone, and each hand surgeon has a different opinion on whether this is helpful. After surgery, a splint or cast is worn for several weeks.
