Thumb Osteoarthritis (CMC)

Thumb Osteoarthritis (CMC Joint Arthritis): Non-Surgical Treatment in Palm Beach

Thumb osteoarthritis, also known as CMC (carpometacarpal) joint arthritis, affects the joint at the base of the thumb where it meets the wrist. It is a very common condition, particularly in women over 50, and can significantly interfere with gripping, pinching, and everyday hand activities.

For appropriately selected candidates, image-guided orthobiologic injection may help manage CMC joint pain and improve hand function without surgery. Give us a call to learn more.

What Is Thumb Osteoarthritis?

The CMC joint is a saddle joint that allows the thumb its wide range of motion, including the ability to grasp, pinch, and oppose the other fingers. When the cartilage in this joint degenerates, the bones rub against each other, causing pain at the base of the thumb that worsens with use.

Signs and Symptoms

• Pain at the base of the thumb, especially with pinching or gripping
• Swelling and tenderness at the thumb-wrist junction
• Reduced grip and pinch strength
• A visible 'bump' or prominence at the base of the thumb
• Difficulty with activities like opening jars, turning keys, or writing

Common Causes and Risk Factors

• Age-related joint degeneration (most common cause)
• Ligament laxity at the CMC joint
• Prior thumb injuries
• Repetitive hand use, including crafts, writing, and musical instruments
• Female sex hormone changes affecting joint ligament stability

How It Is Diagnosed

X-ray imaging of the thumb clearly shows CMC joint space narrowing and the stage of arthritis. Clinical examination includes provocative grind and traction tests specific to the CMC joint.

Dr. Ghattas will review your imaging and functional limitations to determine whether orthobiologic treatment is appropriate.

Conventional Treatment Options

• Thumb splinting to rest the CMC joint
• Hand therapy and joint protection strategies
• NSAIDs for pain control
• Steroid injections into the CMC joint for temporary relief
• Surgery (trapeziectomy or CMC joint replacement): For severe, refractory thumb arthritis

The Palm Beach Regenerative Approach

For patients with mild to moderate CMC joint arthritis, image-guided platelet injection delivered precisely into the CMC joint under ultrasound visualization may help reduce inflammation and support the joint environment.

These treatments do not regenerate cartilage but may help manage pain and improve hand function in appropriately selected patients. Results vary based on the stage of arthritis.

The BioMod Advantage: At Palm Beach Regenerative, treatment does not end with a single injection. Through our BioMod Lab, Dr. Ghattas may combine your orthobiologic procedure with MLS Robotic Laser Therapy to reduce inflammation and support tissue recovery, alongside customized Xymogen supplement protocols designed to optimize your body's healing environment. This integrated, concierge approach is what sets Palm Beach Regenerative apart from a standard injection clinic.

Like all medical procedures, orthobiologic treatments have potential risks and benefits. Results vary by individual. Not all patients are candidates. Dr. Ghattas will discuss your specific situation, realistic expectations, and all treatment options, including when surgery or other interventions may be more appropriate.
