Periprosthetic joint infections (PJIs) are rare, but represent a great burden for the patient. In addition, the incidence of methicillin-resistant For this purpose, sterilized steel implants were implanted into the femur of 77 rats. The metal devices were inoculated with suspensions of two different MRSA strains. The animals were divided into groups and treated with vancomycin, linezolid, cotrimoxazole, or rifampin as monotherapy, or with combination of antibiotics over a period of 14 days. After a two-day antibiotic-free interval, the implant was explanted, and bone, muscle, and periarticular tissue were microbiologically analyzed.Aims
Methods
Vertebral osteomyelitis (VO) is an infection of the spine mostly caused by bacterial pathogens. The pathogenesis leading to destruction of intervertebral discs (IVD) and adjacent vertebral bodies (VB) is poorly described. We aimed to investigate the connection between infection, bone- and disc-metabolism in VO patients. Fourteen patients with VO (infection group) and 14 patients with incomplete burst fractures of the spine (fracture group as controls) were included prospectively. Demographic data, treatment details, laboratory infection markers, and patient-reported outcome were assessed. Tissue biopsies from affected IVDs and adjacent VBs were analyzed for mRNA-expression levels of 18 target genes including chemokines, adipokines and genes involved in bone-metabolism by RT-qPCR.Aim
