Table of content
Symptoms of thumb osteoarthritis
Common symptoms of thumb osteoarthritis include:
- Pain at the base of the thumb, especially with strain
- Swelling and tenderness over the joint
- Stiffness and reduced mobility in the thumb
- Weakness in the thumb grip
- Clicking or grinding sounds during movement
- Pain that worsens with activities such as opening jars or turning doorknobs
Causes
Thumb osteoarthritis occurs when the cartilage in the CMC joint gradually breaks down, causing the bone surfaces to rub against each other. Factors that can contribute to the development of basal 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, physical examination, and imaging. The doctor may perform specific tests to assess pain and mobility in the thumb. X-rays are used to confirm the diagnosis and evaluate the degree of cartilage breakdown and the presence of bone spurs.
Treatment
Treatment for thumb osteoarthritis aims to relieve pain, improve function, and prevent further joint damage. Treatment options include:
- Self-care and relief: Use of thumb splints or orthoses to stabilize the joint and reduce strain.
- Physiotherapy: Exercise programs to strengthen the muscles around the thumb and improve mobility.
- Medication: Painkillers and anti-inflammatory drugs to reduce pain and inflammation.
- Corticosteroid injections: Injections into the joint to relieve inflammation and pain in more severe cases.
- Surgery: In severe cases that do not respond to conservative treatment, surgery may be considered, such as removal of the trapezium bone or joint fusion.
Prevention
To prevent thumb osteoarthritis, it is important to avoid overuse of the joint by:
- Varying tasks and taking regular breaks
- Using ergonomic aids for repetitive movements
- Strengthening hand and thumb muscles through regular exercise
- Avoiding activities that cause pain or discomfort in the thumb
