We propose a three-tier clinical classification system that can aid in prognosis and guidance in the treatment of pyogenic flexor tenosynovitis of the upper extremity.
Tuberculosis (TB) is still endemic in many developed countries. Involvement of the hand and wrist at presentation is extremely rare, and the diagnosis is often missed. Operative findings of "rice bodies, millet seeds, or melon seeds" are highly suggestive of tuberculous tenosynovitis. Six patients with TB of the hand and wrist at various stages of disease with characteristic operative findings are reviewed. Four patients had underlying immunosuppression. One patient had previous pulmonary TB, whereas 3 patients had radiographic evidence of previously undiagnosed pulmonary TB. The interval to presentation ranged from 1 week to 2 years. Two patients had median nerve irritation, 3 patients had osteomyelitis, and 1 patient had flexor tendon rupture. Mycobacterial cultures were positive in 4 patients; acid-fast bacilli stain, and polymerase chain reaction were positive in remaining 1 patient; and both stain and culture were negative in the last patient who had history of pulmonary TB. All 6 patients were managed with combination therapy comprising antituberculous chemotherapy and at least 1 debulking tenosynovectomy. Two patients had 2 debridements. Of these 2 patients, 1 underwent wrist arthrodesis during the second procedure. Mean follow-up was 4 years. There were no recurrences after the most recent debridement. The diagnosis of TB of the hand and wrist is often missed. The surgeon has to be aware of the significance of loose bodies when performing routine excision of innocuous looking wrist ganglia. Combination therapy comprising thorough excisional debridement and antituberculous chemotherapy will minimize recurrence of this difficult-to-treat disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
