Traumatic Posterior Hip Dislocation in a 5-Year-Old: A Case Report and Review of the Literature

Traumatic hip dislocations in children are uncommon, yet constitute an orthopaedic emergency. Furthermore, the insignificant mechanism of injury oftentimes leads to a potential miss or delay in diagnosis. The nature of the injury may seem minor so as to not pursue further workup. For this reason it is imperative to have a high index of suspicion, as clinical assessment and judicious imaging are key to obtaining the patient's correct diagnosis. Although there are various complications that may result from such an injury, the most commonly encountered and most catastrophic is Avascular Necrosis (AVN), of the femoral head; early concentric reduction is crucial in minimizing this risk and optimizing patient outcomes.
