Surgical Management of Adult Traumatic Atlantoaxial Rotatory Fixation with Hangman Fracture: Case Report and Literature Review.

Atlantoaxial rotatory fixation (AARF) is a rare type of adult cervical spine injury. The classic symptoms are painful torticollis and limited neck range of motion. To avoid catastrophic consequences, early diagnosis is necessary. The present study presents the successful treatment of a scarce case of adult AARF with a Hangman fracture and a comprehensive literature review. A 25-year-old man presented to the trauma bay with left-sided torticollis after a motor vehicle accident. Cervical computed tomography scans revealed type I AARF. Torticollis resolved after cervical traction with partial reduction, and posterior C1-C2 fusion was performed as part of the therapy. Recognition of AARF after trauma requires a high index of suspicion, and early diagnosis is critical for the achievement of the best possible patient outcomes. Since the combination of a Hangman fracture and C1-C2 rotatory fixation is complex and unique, it must be tailored to the associated injuries.
