Thumb Arthritis
Overview
Thumb arthritis, sometimes referred to as basal joint arthritis or osteoarthritis of the thumb, is a common form of arthritis affecting the joint located at the base of the thumb. It involves wear and tear of the cartilage helping the bones in the thumb joint move smoothly. Thumb arthritis can cause persistent pain, swelling, and decreased strength and range of motion, making everyday tasks difficult. According to the Arthritis Foundation, over 50% of the population over the age of 60 may show signs of thumb arthritis.
Types
Thumb arthritis predominantly falls within the broader category of osteoarthritis, the most common type of arthritis characterized by gradual cartilage breakdown. However, rheumatoid arthritis, an autoimmune condition causing joint inflammation, can also affect the thumb.
Causes
The main cause of thumb arthritis is the wearing away of joint cartilage over time. This wear and tear can be due to age, overuse of the joint, injury, or genetic predisposition. Being a female and age over 40 are other risk factors. Occasionally, certain diseases like rheumatoid arthritis and psoriasis can also lead to thumb arthritis.
Symptoms
Common symptoms of thumb arthritis include:
-
- Swelling around the base of the thumb
-
- Difficulty performing tasks such as opening jars or turning doorknobs
-
- Persistent pain or tenderness at the base of the thumb
-
- Decreased range of motion
-
- Formation of a bump or swelling at the base of the thumb
-
- Stiffness and limited mobility in the morning
Diagnosis
Thumb arthritis is generally diagnosed through a physical examination by a doctor. This examination may involve applying pressure to the thumb or asking the patient to perform certain movements that will test the thumb strength and range of motion. If needed, the doctor may order X-rays to confirm the diagnosis and rule out other conditions.
Treatment Options
Treatment for thumb arthritis aims to relieve pain and restore function in the thumb and hand. Treatment options include:
-
- Non-Surgical Treatments: These may include pain and anti-inflammatory medication, splinting, and physical or occupational therapy.
-
- Surgical Treatments: If non-surgical treatments provide insufficient relief, surgical options such as joint fusion, osteotomy, or thumb joint replacement can be considered.
Living with Thumb Arthritis
Adopting certain lifestyle changes may assist those living with thumb arthritis to manage their symptoms. These include:
-
- Using assistive devices like jar openers, enlarged handles on utensils, etc.
-
- Regular exercise to maintain joint flexibility.
-
- Application of heat or cold compresses for symptom relief.
-
- Pacing activities throughout the day to prevent overuse or straining of the thumb.
