Atlantoaxial Subluxation
Diagnosis of Atlantoaxial Subluxation
Plain x-rays MRI to assess the integrity of the ligaments Atlantoaxial subluxation is usually diagnosed with plain cervical x-rays; however, flexion views may be required to show intermittent subluxation. Views during flexion, as tolerated by the patient, show dynamic instability of the entire cervical spine. If x-rays are abnormal or if they are normal but subluxation is still suspected, MRI, which is more sensitive, should be done. MRI also provides the most sensitive Diagnosis and is done immediately if cord compression is suspected.
