Document Summary
Most of weight bearing on spinal body. Bony tripod: stability, facet (za) joints *** (two point on back) and body. Spinal canal: buffer space between canal and spinal cord changes between top and bottom. Cervical region canal has funnel effect towards the thoracic canal. Some areas are easier to pinch and less room for flexibility. Neutral spine: lordosis (extension, most stable state. Muscle, ligament and disc: muscles close to spine are used for stabilizing, as vertebrae separate, become less stable, most ligaments limit flexion, discs act as shock absorbers. Unstable fractures (fx: bone has deformed in someway, some level of neurological impairment (cord or nerves from cord, buckling. Bottom anterior end snaps off and floats forward. Can happen at any vertebrae but common on c1. Facet dislocations and subluxations: + or fx, not grossly out of place, still contact between joint surfaces.
