Principally the mechanisms for the sort of scoliotic forms of the thoracal spine are quite easy to explain.
The form of the scoliosis is produced by a pathologic pull from the sterno-clavicular-joint (breast-bone/collar-bone joints) and the sterno-costal-joints (breastbone/rib-joints)at the subluxated ribs, which, within the scope of their subluxation, are displaced ventrally (towards the breast), which again causes a pull from the concerned ribs at the vertebrae.
The cause for, i.e. the primarily pathologic mechanism of a scoliosis of the in the back located thoracal spine comes from a pathologic pull on the sterno-clavicular joints and its in the consequence subluxated collar bones and ribs, i.e. from findings in the front thoracal area.
The bones of the thorax are in steady motion due to movements of the arms, to turnings and bendings of the upper body. The movability is warranted by the jointed connection of the ribs from the front breastbone to the rear positioned vertebrae.
At accidents, for example a fall onto the arm or chest, or due to one-sided carrying of heavy things, the front thoracal joints subluxate. These are the sterno-clavicular and the sterno-costal joints.
Because, how it happens at each accident, at the same time the pelvic damages in the sense of the SMT® get worse, so that a higher tension develops in the back- and thoracal muscles, which again is the reason, why the thoracal joints cant in their subluxation position and do not glide back into the resting position.
The most important finding of a subluxation in the front thoracal area is the one of the sterno-clavicular joints, because their abnormal position determines first, on which side subluxations of the sterno-costal joints happen. Also if subluxations of the front thoracal joints are the first and most important findings, the possible finding-constellations in the front thoracal area and the thoracal spine including the 7th cerebral vertebra are very complexe, so that in these synoptic tables they cannot be described in detail.
