Extensor tendon problems in rheumatoid arthritis.

Abstract

Extensor tenosynovitis is a common presenting upper extremity problem and, unless it resolves with medical management, preventative tenosynovectomy is indicated to prevent tendon rupture. When a rupture has occurred, tendon reconstruction with either a transfer or a graft has a reasonable chance of restoring function as long as the number of tendons involved is limited. Rupture of a single extensor tendon requires surgical treatment to eliminate the cause and prevent further damage, as well as repairing the injured tendon. It is important to give consideration to associated wrist and MP joint problems before, during, or after treating tendon abnormalities.
