Traumatic hip dislocation in childhood is rare. Factors predisposing to abnormal results are delayed reduction and severe trauma. We experienced 8 year-old girl with traumatic posterior hip dislocation and treated with immediate closed reduction. At 30 months follow-up, our patient had good functional and good roentgenographic result with no posttraumatic arthritis or posttraumatic avascular necrosis. So we report this case with review of literature.
