BASAL JOINT OSTEOARTHRITIS
If you suffer from osteoarthritis or severe thumb pain, please Schedule an appointment with one of our orthopedic specialists as soon as possible.
What is Basal Joint Osteoarthritis?
Basal joint osteoarthritis, also known as thumb arthritis or carpometacarpal (CMC) joint arthritis, is a condition that affects the joint at the base of the thumb. Osteoarthritis is the most common form of arthritis and occurs when the protective cartilage that cushions the ends of bones wears down over time. In basal joint osteoarthritis, the cartilage within the basal joint gradually deteriorates, leading to joint pain, stiffness, and loss of function. It is often associated with aging and repetitive use of the thumb joint over time. Other risk factors include a family history of arthritis, previous thumb injuries, and certain occupations or activities that involve repetitive thumb movements.
Indication of Basal Joint Osteoarthritis
Patients with Basal Joint Arthritis may find it difficult to complete actions such as turning a doorknob or opening small containers. Orthopedic Hand & Wrist Specialists often treat this osteoarthritis of the thumb with a combination of splints and prescription medication. Only the most severe Basal Joint Osteoarthritis may require thumb joint replacement.
Common symptoms of basal joint osteoarthritis include:
- Pain: Persistent pain at the base of the thumb, particularly with activities that involve gripping or pinching.
- Swelling: The joint may appear swollen or feel tender to the touch.
- Stiffness: The thumb joint may feel stiff, making it difficult to move the thumb freely.
- Weakness: Weakening grip strength or difficulty performing tasks that require thumb opposition, such as opening jars or turning keys.
- Limited Range of Motion: The ability to fully move or extend the thumb may be reduced.
- Instability: The thumb may feel loose or unstable, causing a sensation of the thumb “slipping” out of place.
