Objective The records of 62 patients with clinical and radiographic evidence of vertebral osteomyelitis and positive bacteriological diagnosis, seen between 1979 and 1996, were reviewed in order to gather data on the epidemiology and the clinical pattern displayed by patients with this condition in northern Spain.
Results Staphylococcus aureus (15 cases), Mycobacterium tuberculosis (15 cases) and Brucella melitensis (13 cases) were the microorganisms most frequently found in our patient series.
After improvement of the sanitary and hygienic control of food products, the role of Brucella melitensis is decreasing as a causative agent (only 3 cases in the last 6 years).
Stapylococcus epidermidis, present in 4 cases (6.6%), should be suspected in elderly patients with previous intravenous cannulations (3 of 4 cases).
The most frequent risk factors were alcoholism (7 cases), chronic hepatic disease (7 cases), diabetes (6 cases) and previous surgery (6 cases).
Delay in diagnosis was high (the mean number of days between the onset of symptoms and diagnosis was 125).
The lumbar region was the most commonly affected site.
Neurologic involvement was present in 10 patients on admission (16%). ESR was>50 mm/hr in a high number of cases.
Blood cultures were found to be the most valuable routine test.
Plain x-rays were normal in 10 patients (16%) ; in 6 of them Staphylococcus aureus was the responsible organism.
Other imaging modalities showed a high sensitivity. (...)
