|Proper spinal curves permit normal turning and bending. Openings between joints allow nerve roots to exit the spine without interference. The edges of the bones are smooth and well defined. Equal disc spacing is a sign of healthy spinal function.
||Loss or normal curves and misalignment restrict or exaggerate normal ranges of motion. ligament and muscle strength is reduced. Even with nerve irritation and soft tissue inflammation, pain or other obvious symptoms may not be present.
||Years of accumulated calcium deposition are now visible. Bone spurs attempt to fuse malfunctioning joints. Adjacent surfaces are rough and uneven. Joint instability is accompanied by continued nerve irritation and disc degeneration.
||After years of neglect, complete fusion has immobilized the joint. Obstructed nerve openings cause permanent nerve irritation as soft tissue degeneration continues. This irreversible condition is usually associated with other chronic health problems.
