Low-virulent skin organisms are primarily responsible for delayed infections. Intraoperative seeding followed by subclinical quiescent periods appears to be the method by which infection occurs. The increased bulk and modularity of modern instrumentation systems can lead to inflammation and bursa formation, thus contributing significantly to the activation of these infections. Primary wound closure results in successful wound healing. Delayed closure after 48 hours is unnecessary. Short-term postoperative parenteral antibiotics (2-5 days) followed by short-term oral antibiotics (7-14 days) is recommended.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
