[Spondylitis and medullary transverse syndrome caused by Staphylococcus aureus].

Three cases of haematogenous osteomyelitis in the vertebral column caused by Staphylococcus aureus are reported. The cases, which were associated with severe neurological symptoms and/or death, were initially characterized by a long period with no or discrete local signs of infection and by values of temperature and leucocyte counts within or close to normal values. In this period measurements of the sedimentation reaction and C-reactive protein were elevated, and were markers of persistent infection. At the Department of Clinical Microbiology in the county of Copenhagen blood cultures from a total of 49 patients were found to be positive for S. aureus during the period January to March 1996. Six patients were found to have osteomyelitis (12%, including four cases of spondylitis) and nine patients were suspected of having osteomyelitis. This frequency of patients with S. aureus bacteraemia having osteomyelitis was significantly higher than reported in another Danish study (10), which together with the severe outcome of the infection emphasizes the need for attentiveness to these serious complications of S. aureus bacteraemia.
