Septic hip dislocation in a child.

A 4-year-old girl presented with pain and disability of right side hip of about 1-week duration. High-grade fever and upper respiratory tract infection were also noted. A pelvic computed tomography scan showed a dislocated hip accompanied by a huge intrapelvic abscess. Culture of pus from the hip showed Streptococcus pneumonia. Emergency arthrotomy, drainage of abscess and reduction of hip, and immobilization with a hip spica cast were undertaken. Thereafter, intravenous antibiotics were given for 6 weeks. The infection was resolved. At a 2-year follow-up, the clinical result was fair and the radiography showed persisting hip damage.
