Origin: Anc Greek
>κύφος/kyphos(=bent forward, humped) > κύπτω/kypto(=bent)
+ σκολίωσις/sκoliosis (=scoliosis)
>(noun) scolios/skolios(=bent, twisted or curved)
+>-ωσις/osis(=osis, suffix meaning a medical condition)
The ancient Greek phycisian Galen of Pergamon (130–200 AD) described four types of spinal deformities, namely kyphosis when they spinal column moves backward, lordosis when it moves forward, scoliosis when it moves to the side and succussion, where there is no spinal deformity but the intervertebral articulations still have moved. He comments that Hippocrates used the term scoliosis to describe all spinal deformities.
Kyphoscoliosis is a compination of kyphosis and scoliosis in which the spine is twisted and curved both backwardly and sideways(lateraly).
