Workup
Laboratory Studies
- Routine laboratory studies: These are generally not indicated because the injured population is usually young and healthy. Diagnosis of infection is clinical.
- Wound culture: Microbiology of human bite wounds is fairly consistent, yet an untreated infected bite generally is cultured if purulence is present.
Imaging Studies
- Radiography
- In closed-fist injuries, an underlying metacarpal head fracture is possible. This may dictate inpatient treatment.
- Infected bites of the hand of some duration may have evidence of osteomyelitis on plain radiographs.
- If history indicates that a tooth was broken during the incident, a radiograph may be indicated to examine for a foreign body.
Procedures
- Wound care
