Summary

Background:

Pyogenic flexor tenosynovitis (PFT) is a common and severe hand infection. Patients who present early can be treated with intravenous antibiotics.

Objectives:

To determine whether PFT caused by animal bites and treated with antibiotics leads to a different outcome than other disease etiologies due to the extensive soft tissue insult and different bacterial flora.

Methods:

We conducted a retrospective cohort study of 43 consecutive patients who presented with PFT between 2013 and 2020. The 10 patients who presented with PFT following an animal bite were compared to those who presented with PFT caused by any other etiology.

Results:

Patients who were bitten pursued medical attention sooner: 1.9 ± 1.4 days compared with 5.3 ± 4.7 days (P = 0.001). Despite the quicker presentation, patients from the study group received similar antibiotic types and duration as controls. All patients were initially treated with intravenous antibiotics under surveillance of a hand surgeon. One patient (10%) from the study group and four controls (12%) were treated surgically (P = 1). Average follow-up was 17 ± 16 days. At the end of follow-up, one (10%) patient from the study group and three (9%) controls sustained mild range of motion limitation and one (3%) patient from the control group had moderate limitations (P = 0.855).

Conclusions:

Intravenous antibiotic treatment, combined with an intensive hand surgeon follow-up, is a viable option for the treatment of PFT caused by animal bites.
