Pedicle Screw Configuration for Thoracolumbar Burst Fracture Treatment: Short versus Long Posterior Fixation Constructs with and without Anterior Column Augmentation.

Study Design: An in-vitro study.

Purpose: The current study is aimed at investigating the differences in stability between short posterior fixation (SPF), hybrid posterior fixation (HPF), and long posterior fixation (LPF) with and without anterior column augmentation using calcium phosphate bone cement (CaP) for treating burst fractures (BFs).

Overview Of Literature: The ideal treatment for thoracolumbar BF is controversial regarding the use of short or LPF constructs.

In vitro biomechanical study to quantify range of motion, intradiscal pressure, and facet force of 3-level dynamic stabilization constructs with decreased stiffness.

Study Design: An in vitro biomechanical study.

Objective: To perform in vitro biomechanical testing on a lumbar spine using a 6-degree-of-freedom machine. To compare the range of motion (ROM), intradiscal pressure, and facet force of different 3-level dynamic stabilization constructs with traditional rigid constructs.

Biomechanical evaluation of a novel posterior integrated clamp that attaches to an existing posterior instrumentation for use in thoracolumbar revision.

Study Design: An in vitro biomechanical study.

Purpose: To evaluate the biomechanics of a novel posterior integrated clamp (IC) that extends on an already implanted construct in comparison to single long continuous bilateral pedicle screw (BPS) and rod stabilization system.

Overview Of Literature: Revision surgery in the thoracolumbar spine often necessitates further instrumentation following a failed previous back surgery.

Cyclic loads do not compromise functionality of the interspinous spacer or cause damage to the spinal segment: an in vitro analysis.

Study Design: A biomechanical study to evaluate the effects of interspinous spacer under cyclic complex loading.

Objectives: To determine the risk of device migration and to assess damage on the device and specimen under extreme coupled motion. Another objective was to evaluate the effect on vertebral foramen and canal dimensions after spacer implantation.
