Pediatric Hip Dislocations
Pediatric hip dislocations are a rare event that carry significant risks for long term disability if managed inappropriately. Often a low energy mechanism is seen in children younger than 10, while a higher energy mechanism is typically seen in adolescents as bone and soft tissue structures become more rigid. Ideally, Closed reduction should take place within six hours to limit the risk of osteonecrosis1. Post reduction x-rays should be carefully scrutinized to evaluate joint space asymmetry. Any asymmetry should be evaluated with CT and MRI to evaluate for labral, capsule, or ligamentum teres interposition in addition to osteochondral fragments. About 25% of pediatric hip dislocations will have interposed labrum or osteochondral fragments
