Abstract

Osteomyelitis of the pelvis is rare in children as well as in adults. This explains why the diagnosis is often missed, so that the infection becomes chronic. The authors report five chronic paediatric cases, seen between 1993 and 2003. The diagnosis was initially missed in two patients. In two others, the osteomyelitis was recognised but insufficiently treated, so that it also became chronic. The fifth patient developed exogenous osteomyelitis 6 months after an open pelvic fracture. The bone scan was useful for the differential diagnosis, but laboratory and radiographic findings were not. Treatment was the same for all patients, including wide surgical debridement, antibiotic therapy and prolonged immobilisation. Four patients were free of symptoms at the last clinical evaluation, after an average follow-up period of 7 years. Only one patient had a recurrence 3 months postoperatively and was re-operated. This study demonstrates that surgical treatment of chronic pelvic osteomyelitis in children and adolescents yields encouraging results.
