Background The standard of care for treatment of pyogenic flexor tenosynovitis (PFT) involves antibiotic therapy and prompt irrigation of the flexor tendon sheath, traditionally performed in the operating room. With the acceptance of wide-awake local anesthesia no tourniquet (WALANT) hand surgery and its potential ability to minimize time to flexor tendon sheath irrigation, we sought to determine whether closed irrigation of the flexor tendon sheath could be safely and effectively performed in the emergency department setting with WALANT technique. Methods A retrospective review was conducted of the senior author’s hand surgery consultations over a 12-month period. Six patients were identified who were diagnosed with PFT and subsequently underwent irrigation of the flexor tendon sheath using WALANT technique. Patient outcomes such as length of hospital stay, need for reoperation, infectious etiology, perioperative complications, and postprocedure range of motion (ROM) were identified. Results Six patients with diagnosis of PFT underwent irrigation of the flexor tendon sheath in the emergency department with local anesthesia only. The irrigation procedures were all well-tolerated. One patient required reoperation due to lack of appropriate clinical improvement following initial irrigation. Four of 6 patients regained their preinjury ROM while the remaining 2 patients had mild proximal interphalangeal joint extension lag. There were no complications associated with the procedures. Conclusions Surgical treatment of PFT with closed irrigation of the flexor tendon sheath in the emergency department utilizing WALANT technique was safe, effective, and well-tolerated. Local anesthesia alone can be used effectively for irrigation procedures of the flexor tendon sheath.
