Delayed Infections After Posterior TSRH Spinal Instrumentation for Idiopathic Scoliosis

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.
