The Therapeutic Evaluation of Spinal Canal Decompression by Using the TBEIS Technique in the Treatment of Lumbar Spinal Stenosis

Figure 3

Schematic diagram of the decompression range of the spinal canal. In the axial view, the decompression range includes the front space of the entire spinal canal and the rear space of the ipsilateral spinal canal (a–c). In the sagittal view, the decompression range of the canal height starts from the exiting root of the same segment to the upper third of the lower vertebra (d).
