Eikenella corrodens in Human Bite Infections of the Hand

Abstract
Over 5.5 yr, 30 patients were found with E. corrodens infections of the hand following closed fist injury. Of the patients, 24 had mixed infections; 6 grew pure cultures of Eikenella. Patients (21) had positive cultures from an injured metacarpophalangeal joint. A delay in presentation or an inaccurate initial diagnosis appeared to be the most significant factors leading to the complications of osteomyelitis (in 5 patients) and significant loss of joint function (in 8 other patients). Clinicians must be suspicious when evaluating any hand injury. Clenched fist injuries of the hand should be treated by early adequate surgical debridement followed by i.v. penicillin, given until operative cultures confirm or deny contamination with E. corrodens.
