The wrist consists of two rows of bones, four bones in each row called the carpals. The long thin bones of the hand radiate out from one row of carpals and form the basis of the fingers and thumb. The radius and the ulna are the two bones of the forearm that form a joint with the first row of carpals.
Swelling of the tendons results in friction and pain with certain thumb and wrist movements. Tendonitis may be caused by overuse or rheumatoid disease.
