In the Dubai Camel Hospital at least, veterinarians perform operations on a camel on a slab with a hole in the center.
The operating slab is tilted and turned so that it fits down over an upright camel.
The hump goes through the hole in the center of the table.
While the camel is knocked out, the table mechanically moves back around into a flat position, allowing the camel to do what it can’t normally do in nature.
Lie on its back with all four legs in the air.
