Sacroiliac joint dislocations frequently occur in a context of high-energy polytrauma. When there is disruption of the pelvic ring, sacroiliac joint displacements are more often posterior and combine two lesions: either lesions of the pubic arch as well as the posterior arch or bilateral lesions. The case we report here lacks these two characteristics. This is an isolated unilateral sacroiliac dislocation with no opening lesion of the pubic symphysis or fracture of ilio- or ischiopubic rami and with anterosuperior displacement. After emergency reduction of the dislocation, the secondary fixation was not performed, due to initial hemodynamic instability compounded by deteriorating central nervous system condition.Le texte complet de cet article est disponible en PDF.
