After a lumbar injury, it is necessary to first determine the specific disease that arises after a lumbar injury, and then to make further treatment according to the specific disease. As the most common disease after lumbar injury is lumbar disc herniation. In the acute phase of lumbar disc herniation, it should be treated by lying flat on a hard bed, not getting up, not getting off the floor, not sitting, with three-dimensional computerized traction of the lumbar spine, microwave physiotherapy, blood circulation and blood stasis medication, and dehydration treatment with drugs such as mannitol. Another type of lumbar injury often leads to lumbar muscle strain. The treatment of lumbar strain requires a ban on floor activities during the acute phase, lying flat on a hard bed, microwave physical therapy, blood circulation and blood stasis medication, and symptomatic medications such as oral lumbar pain medication. Another relatively rare type of lumbar spondylolisthesis requires conservative treatment or surgery depending on the degree of lumbar spondylolisthesis.
