Causes
Osteoarthritis of the thumb occurs when the cartilage in the CMC joint gradually breaks down, causing the bone surfaces to rub against each other. Factors that may contribute to the development of thumb osteoarthritis include:
- Aging and natural wear and tear of the joint
- Previous injuries or fractures to the thumb
- Repetitive movements or overuse of the thumb
- Genetic predisposition
- Inflammatory joint diseases
Diagnosis
Diagnosis is made through a combination of the patient's symptoms, a physical examination, and imaging tests. The doctor may perform specific tests to assess pain and range of motion in the thumb. X-rays are used to confirm the diagnosis and assess the degree of cartilage breakdown and the presence of bone spurs.
Treatment
Treatment for osteoarthritis of the thumb aims to relieve pain, improve function, and prevent further joint damage. Treatment options include:
- Self-care and relief : Use of thumb supports or orthoses to stabilize the joint and reduce strain.
- Physiotherapy : Exercise program to strengthen the muscles around the thumb and improve mobility.
- Medications : Painkillers and anti-inflammatory medications to reduce pain and inflammation.
- Cortisone injections : Injections into the joint to relieve inflammation and pain in more severe cases.
- Surgery : In cases of serious problems that do not respond to conservative treatment, surgery may be considered, such as removal of the thumb bone or arthroplasty.

- Vary your work tasks and take regular breaks
