Zusammenfassung
Hintergrund
Die hohen Anforderungen, die implantatassoziierte Infektionen an Patienten, Ärzte und Gesundheitssystem stellen, haben zur Gründung der internationalen Expertengruppe FRI („fracture-related infection“) Consensus Group geführt. Ihr Ziel ist die Formulierung evidenzbasierter Behandlungsempfehlungen.
Diagnostik
Implantatassoziierte Infektionen werden nach dem zeitlichen Auftreten, der Ausdehnung und der Therapiemöglichkeit klassifiziert. Der diagnostische Algorithmus unterscheidet dabei zwischen beweisenden und hinweisenden Diagnosekriterien. Bei Hinweisen auf eine Infektion wird die frühzeitige Gewebebiopsie mit mikrobiologischer und histologischer Aufarbeitung zur Diagnosesicherung empfohlen.
Therapie
Primäres Ziel der Behandlung einer implantatassoziierten Infektion ist die Konsolidierung der Fraktur unter Vermeidung einer Osteomyelitis. Therapieoptionen sind die Implantatentfernung, die Infekteradikation bei einliegendem Implantat oder die Infektsuppression bis zur knöchernen Konsolidierung. Ein multidisziplinäres Team ist notwendig, um die patientenadaptierte chirurgische und antimikrobielle Therapie optimal aufeinander abzustimmen.
Abstract
Background
The high demands that fracture-related infections put on patients, physicians and the healthcare system have led to the establishment of a international group of experts called the Fracture-Related Infection (FRI) Consensus Group, whose aim is to develop evidence-based treatment recommendations.
Diagnosis
Fracture-related infections are classified according to the time of occurrence, extent and treatment options. The diagnostic algorithm distinguishes between confirmatory and suggestive diagnostic criteria. If there are indications of an infection, tissue biopsy with microbiological and histological workup is recommended to confirm the diagnosis.
Therapy
The primary objective of FRI treatment is to achieve fracture consolidation, while avoiding osteomyelitis. Therapeutic options are removal of the implant, eradication of the infection with implant retention or suppression of FRI. A multidisciplinary team is recommended to develop a patient-specific, optimized surgical and antimicrobial therapy.
