The thumb plays a critical role in nearly every hand movement, from gripping and lifting to fine motor tasks. Because of its wide range of motion, the joint at the base of the thumb is exposed to significant stress over time.
This constant use can eventually lead to wear and tear, resulting in osteoarthritis of the thumb. As the condition progresses, it may cause increasing discomfort and functional limitations, sometimes requiring more advanced treatment.
This guide explores how thumb arthritis develops, how it is diagnosed, and the available treatment options to help manage symptoms and restore hand function.
