Bending of the spine backward, with depression of the spinous processes, is extremely rare.
Do not be afraid of leaving a little flesh attached, as this can be easily cut away from the inter-spinous bones afterwards, it being better to have too much flesh attached to them than to find you have cut the skin through on the other side.
Those fin-bones (inter-spinous bones) which protrude inside may be cut fairly short with the scissors, and the flesh nicely scraped off from each side.
