this is very helpful. However, I cannot see fig 1D and 1E. Could you tell me where to find them ? They are improtant figures particularly if I want to avoid injuring spinal cord.

Sorry about that figure legend, I don't know how that old version made it through.
Here's how that figure legend should read:
Figure 1- Laminectomy. (A) Once vertebra T9 is solidly held with the Graefe forceps, score the spine with scalpel between T10 and T11 to facilitate entry of the micro scissors. (B) Carefully slide the micro scissors through the space between T10 and T11(arrow and inset) and cut the pedicles on each side (dashes) to free the dorsal lamina. (C) Flip the lamina up rostrally and cut it off.

Thank you for clarification. when you insert microscissor to cut pedicles, it seems that the scissor tip is turning medially towards spinal cord (figure 1C) rather than laterally as described in the text. Could you explain when and how you turn scissor laterally ?

Figure 1C illustrates the step when you flip the lamina up to cut it off. 1B illustrates the only times when the scissors come in contact with the cord.
