Thumb Pain Could Be Arthritis

If you notice increasing pain with activities as simple as opening a jar or turning a key, it could be arthritis in your thumb, also known as basal joint arthritis. This condition is common in post-menopausal women, with nearly 25 percent of women eventually developing pain and other symptoms due to wear and tear on the joint at the base of the thumb.

The anatomy of the thumb basal joint is made up of two bones, the trapezium and the thumb metacarpal, along with several ligaments to maintain stability. These bones and ligaments are placed under tremendous stress daily. For example, if we pinch the equivalent of 10 pounds at the fingertip, the basal joint is placed under 120 pounds of pressure. The repetitiveness from pinching and grabbing things throughout the day causes the ligaments to become thin, which can lead to abnormal wear and, eventually, arthritis.

Treatment depends on the severity of the disease. Early disease can often be successfully treated with splinting and simple injections. As more conservative treatments become less effective and symptoms become more painful, surgery becomes the best option for pain relief without limiting function.

Diagnosis often entails a simple evaluation and review of radiographs with an orthopedic surgeon who specializes in treating hands and wrists. Once diagnosis is confirmed, the physician and patient can tailor a team approach for the most effective treatment regimen.
