Mechanical properties of porcine spinal segments after intervertebral disc fenestration: an in vitro preliminary study

Fenestration (DF) of intervertebral disc (IVD) is a prophylactic technique described to prevent, in dogs, the extrusion of degenerate disc material against the spinal cord (Forterre et al. 2008). Our hypothesis is that DF has an important role on IVD’s mechanical properties and will result to change rigidity of a spinal segment. The aim of this in vitro study is evaluate the consequences of DF on disc mechanical properties. In this work, we use porcine spine, an interesting model to perform biomechanical tests that can be applied in humans and animals (Dath et al. 2007).
