Trapeziometacarpal Osteoarthritis

Trapeziometacarpal osteoarthritis (pronunciation: truh-PEE-zee-oh-meh-tuh-KAR-puhl os-tee-oh-ar-THRY-tis), also known as thumb arthritis or basal joint arthritis, is a common form of osteoarthritis affecting the thumb.

Etymology

The term "trapeziometacarpal" is derived from the names of the two bones involved in the condition: the trapezium and the metacarpal. "Osteoarthritis" comes from three Greek words: "osteon" (bone), "arthron" (joint), and "itis" (inflammation).

Definition

Trapeziometacarpal osteoarthritis is a degenerative disease that affects the trapeziometacarpal joint, which is located at the base of the thumb. This condition is characterized by the breakdown of the cartilage that cushions the joint, leading to pain, stiffness, and loss of movement.

• Pain at the base of the thumb
• Stiffness and limited range of motion
• Swelling and tenderness
• Decreased grip strength

Causes

The primary cause of trapeziometacarpal osteoarthritis is the wear and tear of the joint's cartilage. Other factors that may contribute to the development of this condition include:

• Age: The risk of developing trapeziometacarpal osteoarthritis increases with age.
• Gender: Women are more likely than men to develop this condition.
• Genetics: Individuals with a family history of osteoarthritis are at a higher risk.

Treatment

Treatment for trapeziometacarpal osteoarthritis typically involves a combination of non-surgical and surgical methods, including:

• Physical therapy
• Pain management
• Surgery
