Vertebral artery damage complicating cervical manipulation

Abstract

Cervical manipulation may result in serious neurologic injury arising specifically from trauma to the vertebrobasilar system. The vertebral arteries are susceptible to trauma at three locations: in the transverse foraminae, at the atlantoaxial joint, and at the occipitoatlantal joint. Because of frequent inequality in the size of the two vertebral arteries, damage to the larger artery may lead to ischemia of the brain stem. Vertebral artery obstruction may be produced by extension with rotation, even within normal ranges of motion. Neurologic injury following manipulation requires accurate diagnosis and prompt manipulation requires accurate diagnosis and prompt anticoagulant therapy.
