kyphosis

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

Pathology

An increased kyphotic angle is seen in the following conditions:

• Scheuermann disease
• spondyloarthropathies
• osteoporosis
• vertebral body fracture
  • compression fracture
  • pathological fracture

A decreased kyphotic angle is seen in the following condition:

• straight back syndrome

Radiographic features

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

History and etymology

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