Carpometacarpal and scaphotrapeziotrapezoid arthritis: arthroscopy, arthroplasty, and arthrodesis.

ABSTRACT

Osteoarthritis of the first carpometacarpal joint is the second most common site of osteoarthritis in humans. Symptomatic isolated scaphotrapeziotrapezoid joint arthritis, though less common overall, is also frequently observed by the hand surgeon. Investigations on the etiology, pathophysiology, natural history, outcomes of traditional treatments, and new forms of surgical techniques have been attracting more interest in the field of hand surgery. The goal of this article is to sort through the current prevailing ideas using recently available literature and to offer a concise, updated guide to further enhance the understanding of thumb carpometacarpal and scaphotrapeziotrapezoid arthritis.
