Septic sacroiliitis. An analysis of 14 patients.

In most joints arthritis is easily diagnosed. This, however, is not the case with infectious sacroiliitis because of the inaccessibility of the sacroiliac joint, due to the anatomic and topographic relations. Fourteen patients with septic sacroiliitis in whom the diagnosis was established between 10 and 90 days after the onset of the disease are reported for a 5-year period. All patients had scintigraphic high uptake and three patients did not show any radiographic changes.
