Hip arthroplasty infection: Current concepts

Abstract

Due to systemic or local antibiotic treatment and other preventive procedures, the incidence of deep hip-prosthetic infections in Scandinavia is less than 1 percent, with the majority hematogenous. Coagulase-negative staphylococci and anaerobes are involved in more than half of the cases. The diagnosis is sometimes difficult; preoperative aspiration often gives misleading results; and granulocyte scanning usually adds valuable information. In deep infection the current strategy is to revise with a two-stage procedure. Revisions should be carried out at specialized centers with bacteriologic competence and sufficient experience with implants.
