Study design Inflammatory cells were studied by indirect immunocytochemistry in experimental full-thickness anulus fibrosus lesions in pigs. Objectives First, to determine the occurrence, by immunocytochemistry, of T lymphocytes and macrophages in ex

Study design Experimental models of intervertebral disc and facet joint degeneration were created in vivo in the porcine lumbar spine for studying spinal kinematics, using a dynamic technique. Objectives To quantify the changes in spinal kinematics a

The viscoelastic response of a lumbar motion segment loaded in cyclic compression was studied in an in vivo porcine model (N = 7). Using surgical techniques, a miniaturized servohydraulic exciter was attached to the L2-L3 motion segment via pedicle f

Study design In this study, a porcine model was used to study whether a nerve reaction in the anulus fibrosus of a lumbar disc or in a facet joint capsule could cause a muscular response in the multifidus musculature. Objectives To determine if there

Study design An in vivo animal model of lumbar segmental instability, involving both passive and active stabilizing components of the spine, was developed. Objective The aim of this investigation was to dynamically study the alterations in segmental

A novel non-radiographic technique for objectively quantifying quasi-static or dynamic intervertebral motion of a spinal motion segment in vivo in human subjects is presented here. The intervertebral motion device (IMD) is an instrumented linkage tra

A fiberoptic system with a microstructure sensor element was used for measuring lumbar intervertebral disc pressure in a porcine model. The fiberoptic pressure sensor was inserted in the disc using a guiding needle. A reference sensor was also introd

STUDY DESIGN A porcine model was used to study whether muscular activation in the paraspinal muscles caused by nerve stimulation in the anulus fibrosus of a lumbar intervertebral disc could be altered by saline injection into the zygapophysial (facet
