The pressure of cervical spine using artificial spiral cord in experimental trauma was
studied to investigate the relationship between cervical canal size and the severity of
spondylosis of spins.
Twelve human cadavsric cervical spine preparations were svaluated based upon their
severity of degenervation and canal size was msasursd in all. and large diameter and
small canals were defined. A drop mass assembly was constructsd with different
combinations of masses to producs 24 possible drop combonations for each preparation.
Pressure was recorded with senosor transduser arrays beneath the artificial spinal cord
in the cadaveric cervical spine. Although the cervical canalsize of specimen does not
correlate with the degree of degeneration. significant differences were observed between
spondylotic cervical canal size and the pressures at experimental trauma in 12.5§® and
developmental canal size in 14.3§® in C5 level(p<0.05). Also, there was statistical
difference in the pressure at C5 level between the specimens in which Pavolv ratio were
more and less than one.
These tresult may indicated that small cervical canals may be correlated with more
severe cord injury than large cervical canals in acute spinal injury.
