8. Dorsal vertebrae in the backbone
The topographic projection area for disorders in the dorsal vertebrae is situated between 68º and 118º, in coronas nº 1, nº2, nº3 and nº 4. The topographic projection area includes all twelve vertebrae and the vertebral discs between them.



Weak dorsal vertebrae
The most representative signs for weak dorsal vertebrae are:
- Alteration in the collar by radial collar, lacuna collar or collar with various alterations. As well as all of the signs which indicate weakness.
In most cases, the space taken up by the collar is greater than normal.
The complete topographic area for the backbone and its disorders is set out in “Study nº 1”.
