Traumatic Atlantoaxial Rotatory Subluxation in Adult: Case Report

Traumatic atlantoaxial rotatory subluxation (AARS) is generally found in pediatric patients, rarely found in adults, being a life-threatening condition especially when early diagnosis is not possible, which can lead to severe late neurological deficits. We describe a 38-year-old patient, victim of physical aggression caused by strangulation attempt who developed AARS, an uncommontraumatic cause. During the hospital care, the early diagnosis allowed us to institute a conservative treatment, which made the case uncommon, since most of the time surgical treatment is imperative. With the patient awake and under analgesia, a closed reduction was performed that promoted immediate pain relief, followed by a prescription of wearing a Philadelphia-type collar for 8 weeks. During the follow-up, cervical spine radiographies demonstrated no subluxation after removing the cervical collar. The patient was asymptomatic after 6months of treatment. This case supports the importance of nonoperative management of AARS in selected cases.
