[Pediatric pelvic trauma].

The main injury mechanism of rare pelvic girdle injuries in children is high-energy trauma with a high rate of accompanying injuries and a mortality up to 6%. Anatomical features often result in complex pelvic trauma. Emergency treatment is based on established standards in adults. Definitive treatment is mostly conservative and implants adapted for children are increasingly used. Long-term consequences have to be considered, especially after unstable pelvic ring injuries. A correlation exists between clinical and radiological results. Due to the difficult radiological assessment, acetabular injuries are easily overlooked. The Salter-Harris classification appears to be prognostically useful. Most acetabular injuries can be treated conservatively. Considerable displacement or additional intra-articular injuries necessitate open reduction and internal fixation. Frequent follow-up examinations up to the end of the growth phase avoid posttraumatic acetabular dysplasia being overlooked.
