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

Figure 5

An illustrative case of central spinal canal and lateral recess stenosis causing dorsoventral neural compression. (a) Axial images of preoperative computed tomography (CT) showing central spinal canal and lateral recess stenosis due to ventral compression caused by an osteophytic spur and hyperplasia of the facet joint and extruded disc and dorsal compression caused by hypertrophy of the ligamentum flavum. (b) Sagittal images of preoperative CT examination showing significant stenosis of the spinal canal. (c) Axial images of postoperative CT images showing that the compressive factors were completely removed. (d) Sagittal images of postoperative CT examination showing sufficient decompression of the spinal canal.
