OBJECT The effects of obesity on lumbar biomechanics are not fully understood. The aims
of this study were to analyze the biomechanical differences between cadaveric L4–5 lumbar …

Background: This study sought to compare index and adjacent-level biomechanics of
cadaveric specimens with mature fusion versus normal spines in intact and acutely fused …

Study Design. Nondestructive flexibility tests were performed in vitro, comparing multiple
conditions of fixation in a single group of specimens. Objective. To compare the biomechanical …

OBJECT The primary disadvantage of the posterior cervical approach for atlantoaxial stabilization
after odontoidectomy is that it is conducted as a second-stage procedure. The goal of …

OBJECTIVE Transvertebral screws provide stability in thoracic spinal fixation surgeries, with
their use mainly limited to patients who require a pedicle screw salvage technique. However…

Object Endoscopic endonasal approaches to the craniovertebral junction (CVJ) and clivus
are increasingly performed for ventral skull-base pathology, but the biomechanical …

OBJECT The Universal Clamp Spinal Fixation System (UC) is a novel sublaminar connection
for the spine that is currently used in conjunction with pedicle screws at the thoracic levels …

Background: Information on the performance of posterior fixation with cortical screw (CS)
versus pedicle screw (PS) trajectories for stabilizing thoracolumbar burst fractures is limited. …

Introduction. Two specific scenarios that may benefit from dynamic lumbar stabilization are
single-level moderate instability, where the stabilizing tissues are relatively incompetent, and …
