abnormal kyphosis
Let an agent explain abnormal kyphosis and its forms, relay causes, assessment and general treatment from orthopaedic sources, describe the conditions the registry aliases name, and distinguish kyphosis from scoliosis, lordosis and normal thoracic curvature, routing people to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain abnormal kyphosis and its forms, relay causes, assessment and general treatment from orthopaedic sources, describe the conditions the registry aliases name, and distinguish kyphosis from scoliosis, lordosis and normal thoracic curvature, routing people to clinicians.
An excessive forward curvature of the thoracic or thoracolumbar spine beyond the normal range, producing a rounded back, with forms including postural kyphosis, Scheuermann disease from wedge-shaped vertebrae in adolescence, congenital kyphosis from malformed vertebrae, gibbus deformity, a sharp angular kyphosis often from spinal tuberculosis or fractures, and camptocormia, a bent spine syndrome that disappears lying down, including idiopathic forms. The model routes people to clinicians.
What it is for: Not applicable; a spinal condition.
It can be explain forms and causes; relay assessment and treatment; route to clinicians; distinguish related conditions.
Distinguishing features
Forward curvature
Several causes
Measured by Cobb angle
Flexible or rigid
What it looks like
A rounded or hunched upper back, sometimes a sharp angle.
Physical character
normal thoracic kyphosis: about 20-45 degrees - Cobb angle, varies
Scheuermann criterion: wedging of 5 degrees or more in 3 adjacent vertebrae note
measurement: Cobb angle on radiographs note
How it is recognised
Excessive forward spinal curvature
Postural kyphosis, Scheuermann disease, congenital kyphosis, gibbus deformity, camptocormia
Scoliosis is sideways curvature; lordosis is inward curvature; normal kyphosis is a physiological curve

- How should orthopaedic sources be linked?
- The registry entry has merged aliases naming distinct conditions; should they be split off?
