title: Eikenella corrodens in human bite infections of the hand.
abstract: Over a 51/2-year period 30 patients were found with Eikenella corrodens infections of the hand following closed fist injury. Twenty-four had mixed infections; six grew pure cultures of Eikenella. Twenty-one of the 30 patients 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 five patients) and significant loss of joint function (in eight other patients). Clinicians must have a high index of suspicion when evaluating any hand injury and clenched fist injuries of the hand should be treated by early adequate surgical debridement followed by IV penicillin given until operative cultures confirm or deny contamination with Eikenella corrodens.
