title: Vertebral osteomyelitis at a Norwegian university hospital 1987-97: clinical features, laboratory findings and outcome.
abstract: Altogether 40 patients aged 13-91 y (average 58 y) with vertebral osteomyelitis were treated at the Bergen University Hospital between July 1987 and June 1997. All patients presented with back pain, 33 (83%) had vertebral tenderness, and 26 (65%) patients were febrile. The duration of symptoms before diagnosis was < 3 weeks in 13 patients, and from 3 to 16 weeks in the remaining 27 patients. C-reactive protein (CRP) level and erythrocyte sedimentation rate (ESR) were elevated in 39 and 38 patients, respectively. Staphylococcus aureus was the most frequent cause of osteomyelitis followed by Streptococcus spp., Escherichia coli and Mycobacterium tuberculosis. Magnetic resonance imaging was superior to other radiological methods and demonstrated changes consistent with osteomyelitis in all 23 patients examined with this method. 35 patients survived. 18/35 surviving patients had pareses and 17 underwent surgery with drainage of abscesses or laminectomy. All 35 patients made a good recovery and only 3 patients experienced permanent pareses. The diagnosis of vertebral osteomyelitis is easily missed, and treatment is often delayed, particularly in the elderly in whom signs of sepsis may not manifest. However, persisting localized pain and tenderness over the spine together with elevated CRP and ESR should prompt the physician to consider vertebral osteomyelitis. Fever and leukocytosis may support the diagnosis, but may not always be present.
