This initial inflammation and pain eventually subsides, and the patient is left with a permanent bony outgrowth that often skews the fingertip sideways.

Osteoarthritis of the hand causes stiffness of the base of the thumb, alongside enlargement of DIP and PIP joints, leading to the formation of Heberden's nodes and Bouchard's nodes respectively. [6] Such firm and bony swellings at the finger joints are caused by the growth of osteophytes .
Bouchard's nodes are hard, bony outgrowths or gelatinous cysts on the proximal interphalangeal joints (the middle joints of fingers or toes). They are seen in osteoarthritis , where they are caused by the formation of calcific spurs of the articular (joint) cartilage .

Knuckle pads are benign subcutaneous fibrotic nodules that are seen in the finger joints and/or the extensor area of the foot.
