Spondylolysis and spondylolisthesis (gliding vertebrae)

Each vertebra has several physically-anatomical weak points, where it is less able to withstand strain and which can break when much force is used. This occurrence is called spondylolysis. If there happens a spondylolysis at the right and the left side of a vertebra, a spondylolisthesis arises, i.e. a gliding of the vertebra.

Now, which forces are responsible for a spondylolysis? In most of the cases of a spondylolisthesis the area around the lumbar spine is affected. Why? In this area we find the strongest back muscles and at the opposite side of the back muscles in the belly the musculus psoas, which is fixed at the ventral side to the vertebral bodies, running downwards into the lesser pelvis and to the trochanter minor, a bony edge at the inner side of the upper leg.

In the scope of pelvic damages in the sense of the SMT® not only the back muscles tense up, but also the m. psoas. Now two opposite forces work onto the lumbar spine, which break the vertebral structure and the vertebra is torn apart at its weak points.

The classical medicine now asserts, due to this step form of the gliding vertebrae, incarcerations of spinal nerves arise, which cause the often extreme sciatic pain of the patients.

This assertion of the classical medicine might in rare cases happen once, in most of the diseases however is absolutely wrong. The true causes for the sciatic pain of the patients are explained in the chapter sciatic ailments.

For the healing of sciatic problems of patients with gliding vertebrae you only have to remove the causal damages, which extremely intensify the tension in the back muscles - it concerns a pelvic damage in the sense of the SMT® - through which the incarcerations and irritations and with it the pain of the sciatic nerve are eliminated, although the extent of the gliding of the vertebrae must not necessarily change.
