The choice of the most appropriate treatment for thoracolumbar or lumbar spine burst fracture remains controversial from conservative treatment to fusion through a posterior or anterior approach. There are many cases where ligamentotaxis is used to reduce the burst fracture. However, indirect reduction using ligamentotaxis is often limited in the magnitude of the reduction that it can achieve. In our patient with severe burst fracture, we were able to restore an almost normal level of vertebral height and secure spinal canal widening by using only ligamentotaxis by posterior instrumentation. Before the operation, the patient had more than 95% encroachment of the spinal canal. This was reduced to less than 10% after treatment.
