Bilateral septic arthritis of the hip with osteitis and psoas abcess in a 17-year-old adolescent.

Septic arthritis remains an important and serious disease of the young because of its high potential to cause permanent sequelae. The hip is the most commonly involved joint in infants and in the young (35%). Most often, patients have a single joint involved. We report here a rare case of septic arthritis reaching both hips, shown by a severe septicemic shock and complicated unusually by a psoas abcess and osteitis in an immunocompetent adolescent.
