The In Vivo Dynamic Material Properties of the Canine Spinal Cord: A Feasibility Study,
Abstract
A study was completed which showed the feasibility of determining the in vivo dynamic material properties of the spinal cord in mongrel dogs. In the initial phase, sinusoidal pressure waves were induced on a fluid-filled thin-walled penrose surgical drainage tube and the wave front was monitored by two micropressure transducers. The wave speed obtained from these measurements was inserted into the Moens-Korteweg relation to determine the Young's modulus for the penrose tubing. The value obtained for the modulus was in excellent agreement with values cited in the literature. In the second phase, a portion of the spinal cord of three dogs was exposed by a laminectomy and then the cord subjected to an identical wave propagation method of procedure as determined in the initial phase.
