Document Summary
The bone becomes infected by one of three modes: extension of soft tissue infection (e. g. , infected pressure or vascular ulcer, incisional infection, direct bone contamination from bone surgery, open fracture, or traumatic injury (e. g. , gunshot wound) . Hematogenous (bloodborne) spread from other sites of infection (e. g. , infected tonsils, boils, infected teeth, upper respiratory infections). Osteomyelitis resulting from hematogenous spread typically occurs in a bone area of trauma or lowered resistance, possibly from subclinical (non apparent) trauma. Patients who are at high risk for osteomyelitis include those who are poorly nourished, elderly, or obese. Also at risk are immunocompromised patients, those with chronic illness (e. g. , diabetes, rheumatoid arthritis), and those receiving long-term corticosteroid therapy. Postoperative surgical wound infections occur within 30 days after surgery. They are classi ed as incisional (su-per cial, located above the deep fascia layer) or deep (involving tissue beneath the deep fascia). If an implant has been used, deep postoperative infections may occur within a year.
