Spinal tumours can occur in the spinal cord and these can be either inside (intradural) or outside (extradural) the dura mater. Most of them will cross to the contralateral side of the cord (via the anterior white commissure) right before synapsing. Access Systems Discectomy Thoracolumbar Interbody Spinal stenosis occurs most often in the lower back and the neck. Below L2, the proprioceptive information travels up the spinal cord in the ventral spinocerebellar tract. These are the rubrospinal tract, the vestibulospinal tract, the tectospinal tract and the reticulospinal tract.

A comprehensive product suite for spinal surgery success We designed our complete portfolio of advanced spinal implant technologies to help surgeons increase efficiency and reduce the stress of spine surgery on patients. Earlier findings by Viktor Hamburger and Rita Levi-Montalcini in the chick embryo have been confirmed by more recent studies which have demonstrated that the elimination of neuronal cells by programmed cell death (PCD) is necessary for the correct assembly of the nervous system.[14].
