An extensor tenosynovitis complicated with extensor tendon rupture revealing a hand tuberculosis.

ABSTRACT

Tuberculous hand tenosynovitis is a rare localization of tuberculosis. It is dominated by flexor tendon involvement; tenosynovitis of the extensor tendons is exceptional. The diagnosis is usually delayed and sometimes overlooked because of the paucity and the chronicity of the symptoms and signs with the patients often seen at the stage of tendon rupture. We, hereby, report the case of a tuberculous tenosynovitis of the extensors of the left hand having evolved into a ruptured extensor tendons to the 4th and 5th digits. The surgical treatment in conjunction with the antituberculous drugs resulted in the healing of this condition.
