THE IMPORTANCE OF THE ANATOMIC RELATION OF THE SPINAL PEDICLE WITH THE NERVOUS ROOTS AT THE THORACIC LEVEL FOR VERTEBROPLASTY
Abstract:
The study asses the relations between the roots of the spinal nerves and the spinal pedicles at a
thoracic level, as well as the importance of these relations in the transpedicular approach for
vertebroplasty. Material and Method: the study was conducted on four adult human cadaver spines. We
measured the distances between the superior and inferior pedicle with the nervous roots and the
diameters of the spinal pedicles. Knowing these values allow a safe transpedicular approach, with
reduced complications. Conclusions: The distance between the superior pedicle and the root of the
spinal nerve presents no clear evolution of values in connection to the level of the vertebra. The distance
between inferior pedicle and the nervous root shows a progressive reduction of the values in the
craniocaudal direction. When referring to the transverse and sagittal diameter of the pedicles we
observe a progressive growth in size of the thoracic pedicles from the level T4 to T12. The complications
can be prevented when surgery techniques are respected and the surgeon is familiar with the Spinal
Anatomy.
