When a patient with a thoracic spine fracture develops low back pain, firstly, it is necessary to exclude the possibility of simultaneous lumbar spine fracture or soft tissue injury around the lumbar spine, and further CT examination of the lumbar spine is required to clarify the diagnosis. Secondly, after excluding the lumbar fracture, it is also possible that the thoracic fracture is accompanied by soft tissue injury around the thoracic spine, resulting in the formation of a local hematoma, which further compresses the dural sac and causes spasm of the ligaments around the vertebral body resulting in lumbar pain symptoms. After a thoracic spine fracture, the patient needs to be bedridden for a long time, and long-term bed rest will lead to disuse atrophy of the patient’s lumbar muscles. During later functional activities of the lumbar region, significant lumbar pain can occur. Finally, thoracic spine fracture can also lead to the destruction of the stability of the spine, resulting in excessive force on the lumbar region and the symptoms of lumbar pain. After a thoracic spine fracture patient has lumbar pain, he can properly perform lumbar massage to stimulate the muscles of the lumbar region to relieve lumbar pain.
