Pyogenic Flexor Tenosynovitis: Evaluation and Treatment Strategies.

Pyogenic flexor tenosynovitis (PFT) is a common closed-space infection of the flexor tendon sheaths of the hand, which remains one of the most challenging problems facing hand surgeons. PFT goes by several names including septic or suppurative flexor tenosynovitis. Adequate treatment requires timely diagnosis and often prompt surgical treatment. However, despite prompt treatment, and regardless of the protocol used, complication rates as high as 38% have been reported in the literature. Moreover, even with successful eradication of the infection, a significant proportion of patients will suffer from continuing pain, swelling, stiffness, loss of composite flexion, weakness, and recurrence potentially requiring amputation. This review will focus on current evidence-based antimicrobial and surgical treatment strategies to maximize treatment outcomes.
