title: Pyogenic arthritis of the sacro-iliac joint. Long-term follow-up.
abstract: Nine cases of sacro-iliac pyarthrosis are presented. The difficulty in localizing the infection is attributable mostly to failure to appreciate the posteriorly situated physical findings. This, and the difficulty with early roentgenographic demonstration of the lesion, may lead to unnecessary abdominal exploration (as in two of our patients) or to prolonged delay in diagnosis and hence spread of the infection. Awareness of the usual physical findings and prompt use of radioisotope scanning to localize the infection led to earlier diagnosis and avoidance of surgery in three patients seen recently. Antibiotic therapy, with or without surgery, led to cure in all patients, with minimum sequelae.
