Heberden’s and Bouchard’s nodes both refer to bony
prominences located in the finger joints. However, they are both in different
locations and are both tested differently on the boards.
Heberden’s nodes
are present in the distal
interphalangeal (DIP) joints, while Bouchard’s
nodes are present in the proximal
interphalangeal (PIP) joints.
Both Heberden’s and Bouchard’s nodes can be found in osteoarthritis. However, the presence
of Bouchard’s nodes (with the absence of Heberden’s nodes) on a board question
can help you in diagnosing Rheumatoid
Arthritis.
This mnemonic will help you to remember the location of
these nodes. If you see Heberden’s nodes think of osteoarthritis, and if you
see Bouchard’s nodes think of rheumatoid arthritis.
Heberden’s
nodes are Higher up on the finger.
Bouchard’s
nodes are closer to the Body.
