Mycobacterium marinum is an uncommon cause of chronic granulomatous flexor tenosynovitis and leads to significant morbidity in the hand. This paper aims to review our treatment of this infection and its clinical outcomes.


We treated five cases of M. marinum flexor tenosynovitis from 2001 to 2006, which were confirmed after 6 weeks of mycobacterial culture.


All the patients were healthy immuno-competent hosts. There was a history of injury by a marine animal in each patient. Presentation was delayed at an average of 32.0 days after the injury. Excisional debridement was performed at an average of 63.4 days after the injury. The average number of debridements performed was 3.4. One patient had to undergo ray amputation to control the infection. The average duration of oral antibiotics was 15.4 weeks. Post-operatively, there were reductions in total active motion in all patients.


A high index of suspicion, based on the history and intra-operative findings, is necessary when managing these patients. This infection runs a protracted course that requires multiple debridements and is associated with poor functional outcome.
