Short summary
The intervertebral disc is submitted to complex loading, which are responsible for variations of the hydrostatic pressure in its structure. The objective of the present work is to determine the internal pressure that promotes the porcine disc disruption. The tests were performed using a hydraulic cylinder that inflates the discs. It was concluded that potential for porcine disc injury may exist at low pressures for and the rupture could occur within intradiscal physiological pressures.
