Arthritis of the thumb basal joint: old and new treatments for a common condition.

Overview

Arthritis of the basal joint of the thumb is a condition that is becoming even more common as longevity increases and more people have active lifestyles in later life. The role of new hyaluronase-based injectable agents is evolving. A number of surgical procedures are effective in treating early-stage arthritis; the commonly performed trapezium resection and ligament reconstruction procedures have been modified by using limited-incision approaches, arthroscopic assistance, and bioengineered materials, as well as metacarpal repositioning osteotomy.
