Treatment of Pyogenic Flexor Tenosynovitis Using Closed Catheter Irrigation

Pyogenic (or suppurative) flexor tenosynovitis (Fig. 1) is an

infection of the flexor tendon sheath that is usually caused by a

penetrating injury and less commonly by hematogenous

spread. Lacerations, punctures, and bites account for most

cases. Four classic findings have been described by Kanavel

(1): (i) Flexed posture of the finger, (ii) Fusiform swelling of the

digit (“sausage digit”), (iii) Exquisite tenderness along (and

limited to) the course of the sheath, and (iv) Excruciating pain

with passive extension of the finger (late finding).
