We present 12 children with late unreduced traumatic posterior dislocation of the hip. All had posterior dislocation and no associated fracture. ⋯ All the hips showed varying degrees of avascular necrosis, with preservation of joint space on roentgenograms. 11 children had an excellent outcome, according to the criteria of Garrett et al. (1979), after a follow-up of mean 26 (24-36) months. We suggest that open reduction is a satisfactory treatment for hip dislocation of any duration in children.
