Resumen

Atlantoaxial subluxation is defined as an instability of the atlas (C1) over the axis (C2), due to failure or rupture of the ligament complex in the C1-C2 joint. It occurs most frequently in childhood, due to atlantoaxial ligament laxity, a common condition at this age group and may have traumatic or nontraumatic causes. The clinical features of this entity are the presence of upper cervical pain, limitation of neck mobility, torticollis and muscle spasm. The treatment of rotatory subluxation should be individualized because there is no evidence in the literature showing the superiority of a particular therapeutic proposal. In this study we describe two cases of atlantoaxial subluxation of traumatic origin in adults and review the literature regarding the main aspects of this entity.
