Document Summary
Most of weight bearing on spinal body. Bony tripod: stability, facet (za) joints *** (two point on back) and body. Spinal canal: bufer space between canal and spinal cord changes between top and botom. Cervical region canal has funnel efect towards the thoracic canal. Some areas are easier to pinch and less room for lexibility. 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 lexion, discs act as shock absorbers. Unstable fractures (fx: bone has deformed in someway, some level of neurological impairment (cord or nerves from cord, buckling. Botom anterior end snaps of and loats forward. Can happen at any vertebrae but common on c1. Facet dislocaions and subluxaions: + or fx, not grossly out of place, sill contact between joint surfaces.
