of Scanning Palpation at the
C-1 and C-2 spinal nerves are unique in their peripheral
distribution. They do not travel through an intervertebral foramen. They
are associated with diarthrodial (freely movable) joints. The occipital
condyles and the superior atlas facets are synovial joints and have no
intervertebral discs. The inferior atlas facets and the superior axis
facets are synovial joints and have no intervertebral discs. This area
has the greatest range of spinal motion. The remaining vertebral bodies
from the axis down to the first sacral articulation are united by intervertebral
discs and are classified as symphyses.
"The course of the first two spinal nerves runs dorsally to the intervertebral joints while all others leave the foramina intervertebralia in front of the articular processes." (Detlef von Torklus and Walter Gehle.)
"The absence of posterior articulations between the head and atlas and between the atlas and axis leaves the first two nerves without actual intervertebral foramina." (Ruth Jackson.)
In the atlas orthogonal program the scanning palpation correlates with the supine leg check to determine when to adjust and when not to adjust the patient. When the scanning palpation is positive in the C-1 and C-2 area it relates to direct neurological insult or neurological insult with resultant trigger point. When the scanning palpation is positive from C-3 to C-7 it relates to muscle spasms, contractions, trigger points, and posterior zygapophyseal joint compression. The doctor of chiropractic is extensively trained and is a specialist in this important science of scanning palpation examination.
