The Not-So-Merry-Go-Round: Traumatic Inferior-Anterior Hip Dislocation in a 9-Year-Old.

ABSTRACT

Merry-go-rounds are not as innocuous as they may seem. Pediatric hip anterior-inferior dislocations are very rare and can be associated with low-energy trauma. Prompt recognition of pediatric hip dislocations is vital, and this should be treated as a time-sensitive orthopedic emergency. Closed reduction within 6 hours minimizes the risk of avascular necrosis (AVN). We present a case of a 9-year-old boy with an inferior-anterior hip dislocation following low energy trauma while playing on a merry-go-round. The patient was emergently brought to the theatre for closed reduction under general anesthesia within 6 hours. At his 12-month follow-up, he has a full range of motion without any pain.
