TRAUMATIC ATLANTOAXIAL ROTATORY DISLOCATION IN THE PEDIATRIC POPULATION

LUXAÇÃO ROTACIONAL TRAUMÁTICA DE C1-C2 NA POPULAÇÃO PEDIÁTRICA

LUXACIÓN ROTATORIA TRAUMÁTICA DE C1-C2 EN POBLACIÓN PEDIÁTRICA

ABSTRACT

Objective:

The treatment of C1-C2 rotatory dislocation remains controversial and surgery is rare. Surgical treatment is indicated when the injury satisfies the instability criteria or when it cannot be reduced. The objective of this study is to analyze the principles and the adaptations necessary for treating these injuries in the pediatric population.

Methods:

A retrospective case series study. Three cases of patients diagnosed with traumatic C1-C2 rotatory dislocation and treated surgically in our hospital were studied. Through critical analysis of the available literature, a practical guide was proposed to establish the principles and competencies for the treatment of these injuries.

Results:

The operated cases were female patients between 8 and 16 years of age, with a diagnosis of traumatic atlantoaxial dislocation. Two patients required preoperative skeletal traction with halo. All patients underwent posterior instrumented arthrodesis, two with a transarticular screw technique and one with mass and C2 isthmic (Göel-Harms) screws. Conclusion:. It is essential to determine if the injury is stable and reducible. We recommend treating this type of injury keeping the criteria and competencies related to the stability, alignment, biology and function of the spine in mind. Level of evidence IV; Case series.
