Base of Thumb Arthritis Base of Thumb Arthritis (126 KB)


Arthritis is a chronic condition where the joint surface (the cartilage) gets thinned and worn away allowing the bone ends to rub against each other. This results in inflammation of the lining of the joint and therefore pain. Most commonplace for arthritis in the hand.


Most commonly there is no specific cause identified, known as idiopathic or primary osteoarthritis. It can be related to trauma, rheumatoid disease or other connective tissue disorders.
