Calcification is mostly due to the deposition of calcium salt components in the blood to the area after the inflammatory reaction or even necrosis of the tissue, causing calcification and hardening of the location, which in turn limits the further expansion of the pathological reaction in the area and facilitates the remission of the inflammation, which can be interpreted as a defensive action against the pathological changes in the structure. Calcification is not a disease of any kind and generally does not require treatment and is reviewed regularly. However, when the calcified structure produces an irritating pressure on the surrounding area, if the calcification of the posterior longitudinal ligament of the vertebral body compresses the spinal cord and produces a condition such as spinal stenosis, which affects the normal lower limb function of the person, the calcified ligament needs to be removed. Calcification is mostly used as a pathological cue to draw the patient’s attention to the structural lesion there and to treat or condition it in a timely manner to prevent changes or aggravation of the disease.
