The term “spondylolisthesis” refers to slipping, or olisthesis, of a vertebra (“spondylos” in
Greek) relative to an adjacent vertebra. The term “spondylolysis” refers to dissolution of, or a …

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 …

Study Design. Human cadaveric biomechanical study. Objective. To determine the fixation

Anterior instrumentation in the treatment of thoracolumbar fractures has progressed significantly
during the past 2 decades. These fixation systems have evolved to meet the anatomic, …

Many clinical trials on chiropractic management of low back pain have neglected to include
specific forms of care. This study compared two well-defined treatment protocols. The …

Study Design. The Alpine goat model for multilevel anterior cervical discectomy and fusion
was used to analyze the use of an intervertebral fusion device to promote an arthrodesis after …

Purpose In this article, we summarize our work on understanding the influence of cervical
sagittal malalignment on the mechanics of the cervical spine. Methods Biomechanical studies …

… AJ Ghanayem (closing): I'd like to start with the last question first. Until you actually open
the abdomen, you don't know if you have a ruptured spleen. And our goal is to help the …

Study Design. Cadaveric human and bovine lumbar spine models simulating the acute
postoperative period were used to compare the biomechanical properties of two designs of …
