@entity9807 (AARF) is a relatively uncommon @entity130 , especially in association with @entity174 of the @entity2270 . The @entity3029 and fixation is normally caused by intercalated facet joints of @entity2270 and atlas. A traumatic AARF in a 21 year old female is presented with special emphasis on the diagnostic and therapeutic approaches. This high velocity @entity130 was caused by a traffic accident. The @entity130 service which was initially involved made the correct diagnosis and tried to reduce the dislocation by skull traction during analgesia and sedation, but without success. For further treatment, the @entity1 was referred to a level one @entity130 center. After completing the diagnostic imaging with MRI and CT for exact delineation of the @entity174 site and determination of ligament damage, a halo fixation for skull traction was installed. This second attempt was also unsuccessful. Only a closed reduction under general anesthesia with @entity121 led to a neutral alignment and congruent joint contact between C1 and C2. Due to the stable @entity174 site and the intact ligaments, a conservative treatment with a stable collar splint was performed.
