Spinal calcification is a disease caused by calcification of the muscles around the spine, the supraspinous ligaments, and the interspinous ligaments. Calcification refers to protein degeneration due to prolonged ischemia and hypoxia in the patient’s ligaments and muscles. Patients can have clinical manifestations of muscle stiffness, pain, and soreness, which can be caused by bending too much or lowering the head too much. If the patient is often hunched over, calcification of the supraspinous and interspinous ligaments may also occur in the thoracic spine, which is very common in clinical practice and is seen in patients who work with prolonged bending and head down as well as hunching. If patients have no symptoms, they can avoid treatment for the time being, as long as they avoid bending and weight-bearing in daily life, and avoid prolonged desk work and head bowing. If patients have symptoms, they can choose symptomatic treatment, and acupuncture and electrocautery are recommended.
