When sacralization of the lumbar spine occurs in a patient, the cause is that the fifth vertebra of the lumbar spine evolves into a sacrum due to long-term chronic strain, strain, trauma and other factors in the patient’s lumbar area. The normal human lumbar vertebrae have five segments, and after lumbar sacralization, they become four segments. Patients will have persistent and chronic lumbar pain, and in severe lumbar sacralization, it will also affect the patient’s bending activities. After the patient develops lumbar sacralization, first of all, the patient should reduce the amount of activities and avoid such unfavorable factors as lumbar strain, strain injury and cold. Secondly, heat treatment can be given to the lumbar region, such as physiotherapy instrument baking electricity, bioelectricity treatment, or low and medium frequency electrotherapy. Once again, a poultice can be applied to the lumbar region to activate blood circulation and eliminate blood stasis, reduce swelling and relieve pain. In addition, the patient can be instructed to take oral anti-osteophytic drugs or blood-boosting drugs, and the lumbar area can be fixed with braces.
