Introduction: The elbow is the most frequently dislocated joint in children, while radius neck fractures account for 1% of all
pediatric fractures. In the literature, two types of fractures have been described in this location associated with elbow
dislocation in which the head is completely displaced with respect to the neck, both types being infrequent. One of them
was described by Jeffrey, who postulated that the displacement and fracture were generated from the spontaneous
reduction of the transiently dislocated elbow. Case description: Following his description, we are going to present the case
of a 9-year-old girl who suffered an isolated radial head fracture-dislocation. After closed reduction, a 180º inversion of the
radial head was observed with respect to its metaphysis, requiring a subsequent open reduction and fixation with
Kirschner wires. Discussion: Since Jeffrey described this fracture mechanism, multiple authors have published cases that
reaffirm his hypothesis. In the same way, new maneuvers have been described that allow the correct reduction of this
fracture while being the least bloody possible. Conclusion: Our purpose is to carry out a review of the literature regarding
this case in order to highlight the importance of a correct initial assessment that Will lead us to the most appropriate
treatment at all times
