From: Historical overview of spinal deformities in ancient Greece
An illustration of Hippocratic board by Apollonius of Kitium showing correction of a spinal deformity by applying stronger force to restore the anatomy of the spine, by using a plank. One end of this plank is adjusted to an incision made in the wall or in the post embedded in the ground. With the hump lying below the plank, one or two assistants press down its opposite end.
