The outpatient treatment of pyogenic flexor tenosynovitis.

Historically, pyogenic flexor tenosynovitis has been treated with surgical debridement followed by hospitalization and administration of intravenous antibiotics. Recently, hand surgeons have treated this disorder on an outpatient basis. We retrospectively reviewed 37 patients with pyogenic flexor tenosynovitis who were managed as outpatients. Each patient underwent operative irrigation and debridement with intraoperative catheter irrigation. Postoperatively, patients were treated with outpatient intravenous antibiotics. Conversion to oral antibiotics was based on intraoperative culture results. Using this protocol, the average length of intravenous antibiotic usage was 3.5 days. Of the 28 patients with documented follow-up, 27 resolved the infection and one had a recurrence of the infection. No amputations were noted. Total active motion measurement was obtained from 15 patients showing good or excellent results in 14 of 15 patients. This preliminary retrospective case cohort suggests favorable results with outpatient treatment of pyogenic flexor tenosynovitis.
