Many patients present to our surgeons at Proliance Hand, Wrist and Elbow with ongoing thumb joint pain. One of the most common diagnoses in that area is arthritis of the first (thumb) carpometacarpal joint. This form of arthritis is so widespread that there are a variety of names for it including basal joint arthritis, thumb base arthritis, and thumb carpometacarpal (CMC) osteoarthritis (OA). Thumb pain is so prevalent that a Swedish study revealed physicians diagnose it in 1.4% of the overall population. Women constitute 78.5% of those affected. Fortunately, patients have access to a wide range of treatment options to alleviate this condition.

How do I know if the pain in the joint of my thumb is due to osteoarthritis?

(Disclaimer: this blog is not meant to provide a diagnosis. You should be evaluated by a board-certified hand surgeon, such as one of our qualified hand specialists, if you are experiencing pain and loss of function in your thumb.)

Symptoms of a Condition in Your Thumb Joint:

  • Patients that present with thumb CMC OA often describe pain at the base of the thumb.
  • The pain can be dull in nature, occasionally sharp and stabbing, and may occur regularly or intermittently.
  • Activities that use a heavy grip or pinch activity, like opening a jar or opening a lock while holding a key, are often the trigger.
  • Patients also commonly have periods of normal use followed by days of debilitating discomfort.
  • Most patients are surprised when an activity or motion they have “done a thousand times before” becomes painful.

When joint pain in your thumb sounds like arthritis, here is what you can do.

Conservative Management of Joint Pain

Initial treatment for thumb carpometacarpal osteoarthritis largely starts with non-surgical options. The goal of conservative management is to help alleviate the symptoms that result from painful inflammation as the joint wears out. Patients have found positive results with avoiding activities involving heavy grip and key pinching type motions. Other patients swear by warm water soaks in the morning and assistive devices like jar openers.

A large family of nonsteroidal anti-inflammatory medications exist, and many studies have proven their reliability in the treatment of hand arthritis. Common medications include ibuprofen and naproxen. There are even over-the-counter gels, like diclofenac, for patients who are unable to take pills.

Splints for Thumb Joint Pain

When medication and activity avoidance doesn’t do the trick we have useful tools such as various splinting regimens. These treatments have shown reliable improvements of pain especially in patients with early forms of the disease. One study found 76% of patients with Eaton stage 1 or 2 reported improved symptoms with regular use of thumb splints any kind. (The Eaton classification is used to classify thumb CMC OA from radiographs with stage one describing the most early changes and level four noted the most severe.) The type of splint didn’t affect the patient outcomes.

Our clinic carries soft neoprene versions, generic plastic ones to stabilize the joint and custom versions that are the most immobilizing. Patients benefit from our unique clinical setup with in-office, skilled hand therapists who can help you find the perfect splint for you.

Exercises Recommended By Thumb Joint Pain Doctors

An Occupational therapist can also teach exercises which help manage some of the instability that occurs with thumb joint osteoarthritis. These exercises are most effective when carefully tailored based on your specific hand recovery. One group of researchers showed that specific exercises can help reduce the thumb joint pain objectively using radiographs.
