It would suggest that the spine running through the chest area(Thoracic region) has increased is curve giving possibly due to Arthritic condition or other problem I think this was common in elderly women and was called a dowagers hump.
Posterior thoracic.
The thoracic spine is from the base of the neck to the bottom of the rib cage. All the thoracic vertebrae - all 12 have ribs attached. The curve the thoracic spine has is called the thoracic curve, or kyphosis. It is normal to have a curve but if the curve is excessive or twists to the side it is abnormal. It can cause problems or if mild most people do not know it is there.
the thoracic and sacral curves
Well, scoliosis is a curvature of the spine. The cervicothoracic part deals with the location of the curve. The cervical region is the neck, and the thoracic is the upper back. So the cervicothoracic scoliosis would be a curvature of the spine in the neck/upper back
Lordosis typically affects the lumbar spine, causing an excessive inward curve. It is less common for lordosis to affect the thoracic vertebrae, as the thoracic spine naturally has a slight outward curve called kyphosis. Any abnormal curve in the thoracic spine can lead to pain and other symptoms.
The term kyphosis, refers to an abnormal and exaggerated rounding of the spine. To use an example, the Hunchback of Notre Dame had kyphosis. Kyphosis refers to the normal convex curvature of the spine as it occurs in the thoracic and sacral regions.
l
The scientific name for the upper back region is the "dorsal region" or "thoracic region." This area includes the thoracic vertebrae and the muscles that run along the upper back.
Scoliosis is curvature of the spine, either cervical, thoracic and lumbar
thoracic curvature and lumbar curvature
You have the convex anteriorly curve of cervical vertebrae. You have the concave anteriorly curve of thoracic vertebrae. Again you have the convex anteriorly curve of lumber vertebrae. The sacrum goes steep backward from the last lumber vertebra. Here no curve is described probably. So you have lardosis of cervical and lumber vertebrae. You have kyphosis of the thoracic vertebrae.
: Vertebrae are posterior (or dorsal) to the sternum and medial to the kidneys.
