Pyogenic Flexor Tenosynovitis: Evaluation and Treatment Strategies.

Overview

Pyogenic flexor tenosynovitis (PFT)is a potentially devastating closed-space infection of the flexor tendon sheath of the hand that can result in considerable morbidity. Management of PFT, regardless of the pathogen, includes prompt administration of empirical intravenous antibiotics and often surgical treatment. However, currently, there is no standardized treatment algorithm for PFT in regards to the need for, timing, or type of surgical treatment. Many utilize a combination of surgical decompression and sheath irrigation. However, despite prompt treatment, and regardless of the protocol used, complication rates can be high, leading to impaired function and even amputation of the affected digit. Further research is needed to elucidate the role of local antibiotics and corticosteroids in treating this condition and potentially preventing the morbid outcomes that are currently seen. This paper reviews the background, microbiology, and treatment options and controversies surrounding PFT.
