In most cases, these bumps are known as nodes and are commonly associated with osteoarthritis. Osteoarthritis is a condition in which the protective cartilage in the joints gradually wears down over time. When this cushioning decreases, the bones begin to rub against each other. In response, the body forms extra bone as a way to stabilize the joint, which results in the hard, raised bumps seen on the fingers.
The most common type of these growths is called Heberden’s nodes. They typically form on the joints closest to the fingertips and can make the skin appear stretched or slightly shiny. This condition is more frequently seen in women, particularly after the age of 45, and may affect multiple fingers as it progresses. Genetics, natural aging, and repeated use or strain of the hands all contribute to how and when these nodes develop.
