[Algorithm for treatment of deep spinal infections and spondylodiscitis with in situ instrumentation]

Due to a significant increase in spinal interventions and in particular spinal fusion procedures, also in elderly and immunocompromised patients, spinal surgeons are increasingly confronted with deep wound infections and/or spondylodiscitis with in situ instrumentation. This occasionally life-threatening complication can be a challenge for even the most experienced physician, not only in the initial diagnosis but also when determining the operative treatment strategy. It is not uncommon that patients must undergo several operations before a deep infection is finally under control. The aim of this article is to suggest an algorithm for the diagnostics and management of this very troubling complication.
