A lumbar 3 vertebral body burst fracture is a comminuted cone fracture with the fracture fragments displaced in all directions. In a lumbar 3 vertebral burst fracture, the fracture fragments may shift backward and compress the spinal cord, resulting in nerve damage, which is a more serious fracture condition. In severe cases, there may be an inability to stand and paraplegia. Surgery is usually required, mainly incisional reduction and internal fixation surgery, which can avoid compression of the fractured vertebrae, stabilize the structure of the lumbar spine, and restore stability as early as possible. In addition, attention should be paid to postoperative wound care, avoiding wound exposure to water, which may lead to wound infection and symptoms such as wound suppuration and oozing. At the same time, it is also necessary to pay attention to rest, avoid strenuous activities, do not bend over and so on. Lumbar 3 vertebral burst fracture needs to receive regular treatment under the guidance of a doctor.
