In the case of fracture of the lumbar 4 vertebrae, it is necessary to go to the hospital and perform X-ray and CT examination of the lumbar spine. The X-ray mainly looks at the degree of fracture compression, and the CT mainly looks at whether there is an occupancy of the fracture fragment in the spinal canal. If the degree of fracture compression is not very obvious and there is no fracture fragment occupying the vertebral canal, conservative treatment can be considered. First of all, bed rest for 1.5-2 months, in addition to bed rest period should also pay attention to skin care, to prevent the formation of pulmonary infection and bedsores. In addition, if the CT shows a fracture in the lumbar 4 spinal canal, it depends on whether the patient has neurological symptoms, but it is recommended that the patient should undergo surgical treatment to decompress the spinal canal to prevent irritation of the cauda equina nerve and the formation of numbness in the saddle area or abnormal defecation.
