Carpometacarpal (CMC) Joint Arthritis
Don’t let thumb pain from carpometacarpal joint arthritis limit your grip, strength, or independence. At Compass Pain and Wellness, we specialize in identifying the underlying causes of thumb joint degeneration and providing advanced treatments designed to restore function and relieve pain.
Overview
What Is Carpometacarpal Joint Arthritis?
Carpometacarpal (CMC) joint arthritis—often called thumb arthritis—is a degenerative condition affecting the joint at the base of the thumb where the first metacarpal meets the trapezium bone of the wrist. This joint is responsible for the thumb’s wide range of motion and allows us to perform critical movements such as gripping, pinching, and grasping objects.
Because the thumb CMC joint experiences significant mechanical stress during everyday activities, it is one of the most common joints in the hand to develop osteoarthritis. Over time, the protective cartilage covering the joint surfaces gradually wears down, allowing bones to rub together and causing pain, inflammation, and reduced hand function. According to the American Academy of Orthopaedic Surgeons, thumb arthritis is particularly common in adults over the age of 40 and can significantly affect hand strength and dexterity.

Expert Analysis
Understanding Carpometacarpal Joint Arthritis
The CMC joint functions like a saddle-shaped joint, allowing the thumb to move in multiple directions. This unique mobility is essential for fine motor tasks such as writing, opening jars, turning keys, and using tools. However, this high degree of movement also places significant stress on the joint over time.
As cartilage deteriorates, patients may begin to experience pain at the base of the thumb, swelling, weakness when gripping objects, reduced range of motion, and a grinding or clicking sensation during movement. In more advanced cases, the thumb may gradually shift out of alignment, leading to visible deformity and worsening pain. Without treatment, CMC arthritis can progressively limit hand function and make everyday tasks increasingly difficult.
Triggers
CMC joint arthritis typically develops due to progressive wear and tear of the thumb joint over time. The repetitive forces placed on the thumb during gripping, pinching, and lifting activities can gradually break down the protective cartilage within the joint.
Other contributing factors may include previous thumb injuries, ligament laxity or instability, repetitive occupational or sports activities, aging, and genetic predisposition. Conditions that weaken joint stability—such as ligament injuries or hypermobility—can accelerate degeneration of the CMC joint by allowing excessive movement between the bones.

Differential Diagnosis
Several conditions can cause symptoms similar to carpometacarpal joint arthritis. These may include De Quervain’s tenosynovitis, scaphoid fractures, wrist ligament injuries, nerve compression syndromes, and other forms of hand arthritis.
At Compass Pain and Wellness, a precise diagnosis is essential before determining the most effective treatment strategy. Our physicians use advanced diagnostic tools including structure-specific diagnostic ultrasound exams, X-rays, MRI imaging, and targeted diagnostic injections to determine exactly which structures within the thumb and wrist are responsible for pain. By identifying whether symptoms originate from the CMC joint, surrounding tendons, ligaments, or nerves, we can create a treatment plan tailored to the patient’s specific condition.
Solutions
At Compass Pain and Wellness, our goal in treating carpometacarpal joint arthritis is to reduce inflammation, improve joint stability, restore function, and slow the progression of joint degeneration. Because the thumb plays such a vital role in daily activities, treatment plans are designed to both relieve pain and preserve hand strength and mobility.
Our physicians combine advanced regenerative medicine with interventional treatments and rehabilitative care to support joint health and improve long-term outcomes.
Treatment options may include:
Joint injections
Occupational therapy focused on improving grip mechanics and thumb stability
