Managing Challenges in Thumb Carpometacarpal Arthritis.

Thumb carpometacarpal osteoarthritis is commonly encountered and multifactorial in etiology, and its management is based on the radiographic stage and surgeon preference. A variety of management strategies exist including ligament reconstruction, arthroscopic débridement, extension osteotomy, open versus arthroscopic total and partial trapeziectomy with or without interposition and/or suspensionplasty, arthrodesis, and total or hemi implant arthroplasty. A review of the literature shows each of these management strategies to be effective in pain relief, but no one procedure has been shown to be superior despite theoretic benefits to preserving trapezial height. The one common denominator is removal of the arthritic contact between the thumb metacarpal and trapezial surfaces.
