'''Heberden's nodes''' are hard or bony swellings that can develop in the [[Interphalangeal articulations of hand|distal interphalangeal joint]]s (DIP) (the joints closest to the end of the fingers and toes).<ref>{{cite book|title=Handbook of Medical-surgical Nursing|date=2006|publisher=Lippincott Williams & Wilkins|isbn=9781582554457|page=630|url=https://books.google.com/books?id=vCzlLiOlVeUC&q=Heberden%27s+node|language=en}}</ref> They are a sign of [[osteoarthritis]] and are caused by formation of [[osteophyte]]s (calcific [[bone spur|spurs]]) of the articular (joint) [[cartilage]] in response to repeated trauma at the joint.<ref>{{cite book|last1=Schoen|first1=Delores Christina|title=Adult Orthopaedic Nursing|date=2000|publisher=Lippincott Williams & Wilkins|isbn=9780781718806|page=[https://archive.org/details/adultorthopaedic0000scho/page/60 60]|url=https://archive.org/details/adultorthopaedic0000scho|url-access=registration|quote=Heberden's node.|access-date=18 January 2018|language=en}}</ref>

Heberden's nodes typically develop in middle age, beginning either with a [[chronic (medicine)|chronic]] swelling of the affected joints or the sudden painful onset of redness, numbness, and loss of manual [[dexterity]]. This initial inflammation and pain eventually subsides, and the patient is left with a permanent bony outgrowth that often skews the fingertip sideways. [[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.

Heberden's nodes are more common in women than in men, and there seems to be a [[Genetics|genetic]] component involved in pre-disposition to the condition.
