[Postoperative osteitis of the pubis: diagnosis, treatment and results]

Osteomyelitis of the pubis is a possible complication of urological and gynaecological surgery. This article reviews this disease which is still a source of controversy.

Between 1984 and 1997, five patients with osteomyelitis of the pubis, following complementary investigations, underwent resection of the symphysis pubis with histological and bacteriological examination, combined with antibiotic therapy. The follow-up was 1.5 months to 4 years.

The time to onset of first symptoms was 2 weeks to 5 years. Pain initially presented inflammatory features during the early postoperative period and subsequently became mechanical as the disease became chronic, with intermittent acute episodes in 3 cases. Radiation of the pain and the abnormalities observed on imaging were predominantly unilateral in all patients. Fever and laboratory signs of inflammation were inconstant. Bacteria were identified in 4 cases in the absence of antibiotics and lesions of chronic osteomyelitis were observed in every case. Antibiotics were administered by intravenous injection for 3 to 7 weeks, then orally for 1.5 to 3 months. Good functional and infectious results were obtained in 4 patients, while the remaining patient presented posterior instability.

Postoperative pubic osteomyelitis is an infectious disease. Acute osteomyelitis, which can be treated by antibiotics in the absence of a collection and bone sequestrum, is distinguished from chronic osteomyelitis, in which every effort must be made to identify the bacteria responsible. Infected tissues must be widely excised in combination with prolonged antibiotic therapy. Posterior instability is the main complication.
