Septic sacroiliitis (SSI) is a rare form of pyogenic arthritis, which unrecognized or inadequately treated may cause longterm morbidity and eventually lasting disability. SSI is most frequently diagnosed among young adults, especially in drug abusers. Based on a literature survey three cases of SSI are presented, each representing characteristic aspects of SSI. The condition should be considered in cases of acute or subacute onset of pain in the gluteal region, hip or low back accompanied by fever. Laboratory findings are variable and non-specific. Definite bacteriologic diagnosis is only achieved in about 75% of the cases. In almost all of the cases, Tc-99m-MDP bone scintigraphy will in almost all the cases show increased uptake in the affected joint within one week after onset of symptoms. Generally antibiotic treatment leads to complete recovery.
