Arthritis of the Thumb Interphalangeal and Finger Distal Interphalangeal Joint.

The distal interphalangeal (DIP) joints are subjected to the highest joint forces in the hand, and at least 60% of individuals older than age 60 years have DIP joint arthritis. Debridement of degenerative distal interphalangeal joints with mild to moderate disease can provide satisfactory outcomes; however, those joints with more severe angular and rotation changes are reliably treated with fusions. Regardless of the fixation method, DIP fusions have high success rates, are well tolerated, and are extremely durable.
