Bilateral asymmetric hip dislocation is a rare injury with a complex mechanism, and treatment of delayed cases is difficult with unpredictable outcomes. We report a case of a 25-year-old man with bilateral asymmetric hip joint dislocation (right anterior, left posterior) and a Pipkin type II left femoral head fracture. His dislocations were reduced under sedation within 4 hours of the accident, but the surgical fixation of his fracture was delayed for 4 days. Hip dislocation should be reduced within 6 hours of injury. Postreduction CT in high-energy trauma is especially crucial for detecting associated fractures. If closed reduction fails, then open reduction should be conducted to prevent complications such as osteonecrosis, heterotopic ossification, and osteoarthritis.
