Sacroiliac joint pyarthrosis.
Sacroiliac (SI) joint infection is rare, and symptoms are idiosyncratic and often confusing. This paper reviews six cases of SI joint infection with regard to their clinical manifestations, diagnostic imaging, and treatment. The six patients were seen over a 15-year period and had a mean age of 16.2 years and a mean follow-up of 44.2 months. The most common presenting symptom was fever (71.4%). The most common physical findings were elevated temperature and limited ipsilateral hip motion. In most cases the white blood cell count and erythrocyte sedimentation rate were elevated, and 71% of the cases had positive blood cultures. The most specific imaging study was the technetium bone scan. All patients were treated with 3 to 6 weeks of appropriate antibiotics and were asymptomatic and had a normal physical examination on follow-up. Routine anteroposterior roentgenograms of the pelvis demonstrated sclerosis of the affected SI joint in one third of the cases. There appeared to be no long-term sequelae in this group of patients.
