Rhizarthrosis, also known as basal joint arthritis, is a degenerative joint condition that affects the base of the thumb where it meets the wrist. The condition is characterized by the wearing down of the cartilage that cushions the joint, leading to pain, stiffness, and decreased range of motion.
Rhizarthrosis is a common condition, particularly among women over the age of 50. It can be caused by a variety of factors, including overuse of the joint, injury, or genetic factors.
