Symptoms
Symptoms common in patients who have thumb arthritis include:
Pain at the base of the thumb Swelling at the base of the thumb Grinding sensations (crepitus) when moving the thumb Painful and limited movement of the thumb Difficulty gripping Pain when opening jars, turning keys, etc.
By examining your thumb, your healthcare provider can usually make the diagnosis of basilar arthritis without any special tests. An X-ray will show the extent of arthritis. The X-ray may also offer some indication of how successful nonoperative treatments may be in your situation.
Most people who have arthritis in the thumb report that their symptoms are worsened by activities, particularly repetitive activities. People who work with their hands, such as manual laborers, or even people who enjoy activities such as knitting or woodworking may notice pain at the base of the thumb as they continue their activities. In fact, those who have an occupation with repetitive movements are twice as likely to develop localized osteoarthritis. Many people with this condition find themselves rubbing or massaging the base of their thumb in order to relieve the discomfort.
Nonsurgical Thumb Arthritis Treatments
The treatments for thumb arthritis include:
Anti-inflammatory medications: A simple anti-inflammatory medication is often a good first step in the treatment process. You should talk to your healthcare provider to discuss the safety of these medications, and the appropriate dose. Often, these medications can relieve symptoms of thumb arthritis. Thumb abduction splints: A splint can rest the arthritic joint and relieve the inflammation associated with thumb arthritis. The splint should be worn during activities that aggravate your symptoms. The thumb abduction splint is the simplest brace to use for this purpose, but in patients with more severe symptoms, a more significant brace, like a thumb spica brace, is appropriate. The thumb spica brace is more supportive of the thumb but more awkward to use in your daily activities. Cortisone injections: A cortisone injection places a powerful anti-inflammatory medication directly at the site of arthritis. This injection usually provides quick relief of symptoms, but the symptoms may return over time.
Surgical Options for Thumb Arthritis
Surgery can be a helpful treatment for patients with severe thumb arthritis. The usual surgical treatment is to remove the arthritic bone, relieving the pain and inflammation of the worn-out joint. There are different surgical procedures to accomplish this goal, including a trapeziectomy. In some situations, your surgeon may choose to replace the removed bone with a tendon graft, with an artificial implant, or with nothing at all. Alternatively, your healthcare provider may consider fusing the joint, to eliminate all motion at the base of the thumb.
The good news about surgery is that, in appropriately selected patients, surgical treatment of thumb arthritis is very successful. Patient satisfaction with surgical treatment is about 90–95%, meaning most patients feel very good after surgical intervention. There are potential complications of surgery, including infection, nerve injury, and persistent pain. Talk to your healthcare provider if you want to know more about the surgical treatment of thumb arthritis.
Other Causes of Thumb Pain
There are other potential causes of thumb pain that need to be considered, especially if simple treatments for some arthritis do not help. Possible causes of thumb pain include:
Carpal tunnel syndrome Trigger thumb Tendonitis
Sometimes these conditions can mimic the symptoms of arthritis of the thumb, and they can also coexist along with arthritis of the thumb. If you were diagnosed with some arthritis, and your symptoms do not seem to be responding appropriately to treatment, your healthcare provider should evaluate for other potential causes of pain. Sometimes these other conditions may need treatment in order to alleviate your symptoms of discomfort.
If the pain is still not improved, and other conditions do not seem to be the source of your discomfort, it may mean that the treatments provided are not adequate to relieve your condition. In that case, more invasive treatments may ultimately become necessary.
A Word From Verywell
While symptoms can typically be managed with simple treatments, arthritis at the base of the thumb is one of the most commonly diagnosed arthritic joints in the body. Most people will respond well to simple treatments. If you do not find relief with these methods, you might consider surgical options.
