From August 1998 to June 2005, we treated 5 children (7 cases) who suffered with traumatic dislocation of hip. The mean follow-up period was 4.1 years (range: 1~8 years). Acceptable reduction was achieved in all cases by first closed reduction. The complications were 2 redislocations in 2 patients, respectively. Closed reduction is an effective method for treating traumatic dislocation of the hip in children and long term follow-up should be performed for detecting late-onset complications such as avascular necrosis, growth disturbance and traumatic osteoarthritis.
