Trapeziometacarpal osteoarthritis is a degenerative joint disease affecting the carpometacarpal joint (CMC) of the thumb. This condition is characterized by the deterioration of the articular cartilage and changes in the surrounding bone structure, leading to pain, stiffness, and reduced function of the thumb.
Anatomy[edit]

The trapeziometacarpal joint is located at the base of the thumb, where the trapezium bone of the wrist meets the first metacarpal bone of the thumb. This joint is a saddle joint, allowing for a wide range of motion, including flexion, extension, abduction, adduction, and opposition.
Pathophysiology[edit]
In trapeziometacarpal osteoarthritis, the cartilage that cushions the joint wears down over time, leading to bone-on-bone contact. This results in pain and inflammation. As the condition progresses, osteophytes (bone spurs) may form, and the joint may become deformed.
Symptoms[edit]
Common symptoms of trapeziometacarpal osteoarthritis include:
- Pain at the base of the thumb, especially during pinching or gripping activities.
- Swelling and tenderness around the joint.
- Reduced range of motion.
- Weakness in the thumb.
- A grinding sensation in the joint.
Diagnosis[edit]
Diagnosis is typically made based on clinical examination and patient history. X-rays can be used to confirm the diagnosis by showing joint space narrowing, subchondral sclerosis, and osteophyte formation.
Treatment[edit]

Treatment options for trapeziometacarpal osteoarthritis include:
Non-surgical[edit]
- Activity modification and rest.
- Use of splints to immobilize the thumb.
- Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief.
- Corticosteroid injections to reduce inflammation.
Surgical[edit]
- Trapeziectomy: Removal of the trapezium bone.
- Arthrodesis: Fusion of the joint to eliminate movement and pain.
- Joint replacement: Replacement of the joint with a prosthesis.
- Osteotomy: Realignment of the bones to improve joint function.]]

Prognosis[edit]
The prognosis for individuals with trapeziometacarpal osteoarthritis varies. Non-surgical treatments can provide relief for many patients, but surgery may be necessary for those with severe symptoms. Surgical outcomes are generally favorable, with most patients experiencing significant pain relief and improved function.
