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.
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.
Wear and Tear: Repeated use of the thumb joint over time.
Injury: Prior trauma or fracture involving the thumb joint.
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.
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.
Splinting:
Custom thumb splints to support the joint and reduce pain during activities.
Pain Management:
NSAIDs or topical anti-inflammatory creams.
Activity Modification:
Learning alternative ways to grip or lift objects to reduce joint strain.
Physiotherapy:
Exercises to strengthen the muscles supporting the thumb joint.
Techniques to improve range of motion and reduce stiffness.
Occupational Therapy:
Assistance with adaptive tools and strategies for daily tasks.
Injections:
Corticosteroid injections to reduce inflammation and pain.
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.

Splint Fitting: Custom-designed splints to support the thumb during recovery.
