Osteoarthritis of the hand preferentially involves the distal interphalangeal (DIP) joint and the carpometacarpal (CMC) joint of the thumb.1 The proximal interphalangeal (PIP) joint is affected less commonly.
The term "osteoarthritis" has been used in the past to describe degenerative changes in the articular cartilage. However, a more descriptive term might be primary idiopathic osteoarthritis.
Synonyms and related keywords: osteoarthritis of the hand, erosive osteoarthritis, distal interphalangeal joint, DIP joint, carpometacarpal joint, CMC joint, primary idiopathic osteoarthritis, arthrodesis, arthroplasty

Scapholunate advanced collapse (SLAC) of the wrist is the most common pattern of degenerative arthritis in the wrist. Watson and Ballet coined the term SLAC wrist in 1984. Findings of bilateral SLAC wrist on a prehistoric skeleton provide paleopathological evidence of the existence of this disease 7000 years ago. The hallmark of the disorder is scaphoid or scapholunate ligament injury with collapse on the radial side of the wrist.

Osteoarthritis (OA) is a degenerative condition in which the articular cartilage on the surfaces of the bones that form joints progressively deteriorates. The terms osteoarthrosis and OA are often used interchangeably. Although inflammation is generally absent in this degenerative condition, most physicians commonly refer to it as OA. Hence, this is the term in daily use.1 OA is common in weight-bearing joints. Although the wrist is not a weight-bearing joint, OA of the wrist is not an uncommon condition that orthopedic surgeons encounter in day-to-day practice. Wrist arthritis is also common in patients with rheumatoid arthritis (RA), which is a systemic autoimmune inflammatory disorder that affects the joints; in the upper limb, the wrist is most frequently affected. RA invariably results in functional difficulty over time.
