Septic separation of the symphysis pubis

Symphysial osteomyelitis has been distinguished from osteitis pubis because of the more serious nature of the disease. We report a case in which there was a pelvic separation similar to that seen after trauma or pregnancy. The previously undescribed complications of bladder perforation and pelvic instability are also noted. There was no predisposing cause in this case, in contrast to the 40 previously reported. The causative organism was staphylococcus aureus, but pseudomonas aeruginosa and escherichia coli have also been found in other cases.
