In the deep groove on the upper surface of the posterior arch of the atlas are the vertebral artery and the first cervical or suboccipital nerve. In the past, the vertebral artery was accessed here in order to conduct angiography of the circle of Willis. Presently, formal angiography of the circle of Willis is performed via catheter angiography ...
The Vertebral Artery Test or Wallenberg Test is a physical exam for vertebral artery insufficiency. Commonly, the VA test involves cervical spine motion to an end-range position of rotation, extension or a combination of both. At this point, the physician assesses for vertebrobasilar insufficiency (VBI) symptoms. If the patient has VBI symptoms ...
Rotational vertebral artery syndrome (sometimes referred to as Bow Hunter's Syndrome) results from vertebral artery compression on rotating the neck. [7] The commonest cause is a bone spur from a cervical vertebra , in combination with disease in the opposite vertebral artery.
Both flexion and extension exercises have been shown to help mitigate back pain [8] and has been demonstrated to accomplish the following: a) significantly increase the canal area, b) increase the midsagittal diameter, c) increase the subarticular sagittal diameter, and d) increase all the foraminal dimensions significantly [9]
Orthospinology Procedure is a method of analyzing and correcting the chiropractic upper cervical subluxation complex based on vertebral alignment measurements on neck X-rays taken from three different directions. The adjustment can be delivered by hand, hand-held, or table-mounted instruments along a pre-calculated vector using approximately 1 ...
Craniocervical instability (CCI) is a medical condition characterized by excessive movement of the vertebra at the atlanto-occipital joint and the atlanto-axial joint located between the skull and the top two vertebra, known as C1 and C2.
Thoracic spinal stenosis, at the level of the mid-back, is much less common. [13] In lumbar stenosis, the spinal nerve roots in the lower back are compressed which can lead to symptoms of sciatica (tingling, weakness, or numbness that radiates from the low back and into the buttocks and legs).
