Pelvic girdle injuries leading to anterior and posterior disruption are rarely 
seen in children. External fixation is useful to reduce and stabilize the pelvis 
in order to control massive blood loss due to severe venous bleeding. The 
anterior tension band element of the external fixator can successfully maintain 
reduction of the pelvic girdle. Dislocation or fracture dislocation of the 
sacroiliacal joint cannot be reduced with simple traction techniques. Leg length 
discrepancy is to be expected when the hemipelvis is displaced. Seven cases of 
this rare injury in children are presented together with the late outcome. 
Treatment modalities are discussed.
