Kyphosis (plural: kyphoses), much less commonly kyphus, is a term used to describe the sagittal curvature of the thoracic spine.

An increased kyphotic angle is seen in the following conditions:

A decreased kyphotic angle is seen in the following condition:

  • traditionally measured using the Cobb angle
    • may over-estimate kyphosis if there is concomitant vertebral end-plate irregularities 1
    • the alternative Cobb 1 or vertebral centroid angles 3 have been proposed to negate the aforementioned over-estimation

Derived from the Greek word kyphōsis, from kyphos meaning humpbacked 4.
