BACKGROUND: Many decompression procedures involve complete or partial facetectomy.
Spinal fusion usually stabilizes the motion segment after complete facetectomies. However …

BACKGROUND CONTEXT: Lumbar fusion is traditionally used to restore stability after wide
surgical decompression for spinal stenosis. The Total Facet Arthroplasty System (TFAS) is a …

Study Design. In vitro biomechanical study investigating L4–L5 kinematics and intradiscal
pressure (IDP) with a facet replacement system. Objective. To assess the influence of the …

Purpose To gain insight into a new technology, a novel facet arthroplasty device (TFAS) was
compared to a rigid posterior fixation system (UCR). The axial and bending loads through …

Study Design. An in vitro biomechanical study to quantify 3-dimensional kinematics of the
lumbar spine following facet arthroplasty. Objectives. To compare the multidirectional …

✓ The clinical success of lumbar spinal fusion varies considerably, depending on
techniques and indications. Although spinal fusion generally helps to eliminate certain types …

Study Design. A study using an anatomically accurate finite-element model of a L2–L3
motion segment to investigate the biomechanical effects of graded bilateral and unilateral …

Study Design. Biomechanical study using human cadaveric lumbar spines. Objective. To
