Photos of the decompression operation. a After the T13 lamina was ground off with a high-speed microdrill, the cotton strip (black arrow and area surrounded by black dotted lines in the magnified picture) was completely exposed. b The cotton strip was carefully removed with microscopic tweezers. Because the dura mater is very weak, care was taken to prevent rupture of the dura mater during the removal.

The black arrow refers to blood vessels on the surface of spinal cord. All procedures were performed under a ×16 surgical microscope
