Transient ischemic attacks (TIAs) and cerebellar signs may reflect vertebral artery impingement from cervical subluxation or basilar artery impingement from upward migration of the dens. Tenosynovitis of the transverse ligament of C1 may lead to C1-C2 instability. Myelopathy secondary to rupture of the transverse ligament may lead to neurologic deficits. Radiculopathy is most common at the C2 root, though symptomatic subluxations may occur at any level.
