A total of 2,905 pedicle measurements were made from T1–L5. Measurements were made
from spinal computerized tomography (CT) scan examinations and individual vertebral …

Study Design. Change in lumbar lordosis was measured in patients that had undergone
posterolateral lumbar fusions using transpedicular instrumentation. The biomechanical effects …

Study Design. An experimental approach was used to test human cadaveric spine specimens.
Objective. To assess the response of the whole lumbar spine to a compressive follower …

Study Design. A study of the transforaminal lumbar interbody fusion and the posterior lumbar
interbody fusion techniques was performed. Objectives. To describe the transforaminal …

Prior to implantation, medical devices are subjected to rigorous testing to ensure safety and
efficacy. A full battery of testing protocols for implantable spinal devices may include many …

A 3-D finite element model (FEM) of the lumbar spine (L1–S1) was used to determine the
effect of a large compressive follower pre-load on range of motions (ROM) in all three planes. …

Traditional experimental methods are unable to study the kinematics of whole lumbar spine
specimens under physiologic compressive preloads because the spine without active …

Study Design. An experimental approach was used to test human cadaveric cervical spine
specimens. Objective. To assess the response of the cervical spine to a compressive follower …

Background Previous clinical studies have shown the safety and effectiveness of balloon
kyphoplasty in the treatment of pathological vertebral compression fractures (VCFs). However, …

Study Design. Human cadaveric biomechanical study. Objective. To determine the fixation
strength of laterally directed, cortical pedicle screws under physiological loads. Summary of …
