A comminuted fracture has occurred in the lumbar vertebrae, and the treatment method should be chosen based on the degree of displacement of the fracture, that is, the occupancy within the spinal canal and the extent of compression of the lumbar fracture. Generally speaking, if there is significant compression inside the spinal canal, and the height of the vertebral body of the lumbar spine is also greatly compromised, surgical intervention is necessary to restore the height of the vertebral body. If necessary, decompression inside the spinal canal should be performed to relieve pressure on the spinal cord, alleviate symptoms, and facilitate early functional recovery of the patient.
