Bony bumps on the middle joint of the finger are known as Bouchard's nodes.

Similar nodes can develop around the finger middle joints, known as Bouchard's nodes.

These are known as Heberden's and Bouchard's nodes .

The Heberden's and Bouchard's nodes may not be painful, but they are often associated with limitation of motion of the joint.

His name is also lent to the eponymous "Bouchard's nodes", which are bony outgrowths of the proximal interphalangeal joints, and are a sign of osteoarthritis.

Bouchard's nodes are hard, bony outgrowths or gelatinous cysts on the proximal interphalangeal joints (the middle joints of fingers or toes.)

Bouchard's nodes are comparable in presentation to Heberden's nodes, similar osteoarthritic growths on the distal interphalangeal joints, but are significantly less common.

Bouchard's nodes may also be present; these are similar bony growths in the proximal interphalangeal (PIP) joints (middle joints of the fingers), and are also associated with osteoarthritis.

Osteophytes on the fingers or toes are known as Heberden's nodes (if on the distal interphalangeal joint) or Bouchard's nodes (if on the proximal interphalangeal joints).

Bony bumps on the finger joint closest to the fingernail (Heberden's nodes ), bony bumps on the middle joint of the finger (Bouchard's nodes ), or bony bumps at the base of the thumb.

In smaller joints, such as at the fingers, hard bony enlargements, called Heberden's nodes (on the distal interphalangeal joints) and/or Bouchard's nodes (on the proximal interphalangeal joints), may form, and though they are not necessarily painful, they do limit the movement of the fingers significantly.
