Pyogenic Flexor Tenosynovitis: Evaluation and Management

Pyogenic flexor tenosynovitis is a closed-space infection that can lead to a devastating loss of finger and hand function. It can spread rapidly into the palm, distal forearm, other digits, and nearby joints. Healthy individuals may present with no signs of systemic illness and often deny any penetrating trauma or inoculation. Early diagnosis and prompt treatment are required to preserve the digit and prevent morbidity and loss of hand function. Many treatment options have been described, although all share 2 common principles: evacuation of the infection and tailored postoperative antibiotic treatment with close monitoring to ensure clinical improvement.
