Review Case Reports
Pyogenic infection of the sacroiliac joint. Case reports and review of the literature.
Three cases of pyogenic sacroiliitis are described, and the English literature from 1878 to 1990 reviewed, for a total of 166 cases. In 1 patient the source of infection was identified at the site of an intravenous line; 1 patient had 2 risk factors for developing the disease (pregnancy and intravenous drug use); and a third patient had no source of infection and no associated risk factors. The diagnosis of pyogenic sacroiliitis was made in each patient by history, physical examination, and positive skeletal scintigraphy or computed tomography of the sacroiliac joint. ⋯ In patients whose blood cultures fail to reveal a causative organism, fluoroscopic guided fine-needle aspiration of the sacroiliac joint under general anesthesia may help to identify the organism. If all cultures are negative, open biopsy of the sacroiliac joint may be required. Open biopsy should also be done if sequestration or an abscess is formed, or if the patient fails to respond to antibiotic therapy.(ABSTRACT TRUNCATED AT 400 WORDS)
