Thumb CMC osteoarthritis, also known as basal joint arthritis, affects the carpometacarpal (CMC) joint at the base of the thumb. This condition is common and can significantly impact hand function, causing pain and limiting the ability to perform daily tasks. At Palms Physiotherapy & Allied Health, we offer expert care to help manage symptoms, restore mobility, and improve your quality of life.

Thumb CMC Osteoarthritis: Comprehensive Care at Palms Physiotherapy & Allied Health

Understanding Thumb CMC Osteoarthritis

The carpometacarpal joint is where the thumb meets the wrist. This joint allows for a wide range of thumb movements, such as pinching, grasping, and rotating. With age or overuse, the protective cartilage covering the bones in this joint can wear down, leading to osteoarthritis.

Symptoms of Thumb CMC Osteoarthritis

• Pain: Especially at the base of the thumb during gripping or pinching.

• Swelling: Around the affected joint.

• Weakness: Difficulty performing tasks like opening jars or turning keys.

• Deformity: A "squared" appearance of the thumb base in advanced cases.

• Loss of Mobility: Reduced range of motion or stiffness in the thumb joint.

Causes and Risk Factors

Primary Causes

• Wear and Tear: Repeated use of the thumb joint over time.

• Injury: Prior trauma or fracture involving the thumb joint.

Risk Factors

• Age: More common in individuals over 50.

• Gender: Women are more likely to develop thumb CMC osteoarthritis.

• Repetitive Motion: Occupational or recreational activities that strain the thumb joint.

• Genetics: A family history of osteoarthritis increases risk.

Diagnosing Thumb CMC Osteoarthritis

Our specialists at Palms Physiotherapy & Allied Health perform a thorough evaluation to confirm the diagnosis:

• Physical Examination: Checking for pain, swelling, and joint mobility.

• Grind Test: Assessing pain when rotating the thumb joint.

• Imaging:

  • X-rays: To detect joint space narrowing, bone spurs, or other arthritic changes.

Treatment Options for Thumb CMC Osteoarthritis

Non-Surgical Management

1. Splinting:

   • Custom thumb splints to support the joint and reduce pain during activities.

2. Pain Management:

   • NSAIDs or topical anti-inflammatory creams.

3. Activity Modification:

   • Learning alternative ways to grip or lift objects to reduce joint strain.

4. Physiotherapy:

   • Exercises to strengthen the muscles supporting the thumb joint.

   • Techniques to improve range of motion and reduce stiffness.

5. Occupational Therapy:

   • Assistance with adaptive tools and strategies for daily tasks.

6. Injections:

   • Corticosteroid injections to reduce inflammation and pain.

Surgical Treatment

For severe cases where conservative treatments fail, surgical options may include:

• Trapeziectomy: Removal of the trapezium bone in the thumb joint.

• Ligament Reconstruction and Tendon Interposition (LRTI): A common surgical technique to restore thumb joint function.

• Joint Fusion: Reserved for advanced or complex cases.
