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

This systematic review provides supporting evidence for a clinical practice guideline for the
management of rapid eye movement (REM) sleep behavior disorder in adults and children. …

Risks associated with fatigue that accumulates during work shifts have historically been
managed through working time arrangements that specify fixed maximum durations of work …

BACKGROUND CONTEXT: Lumbar fusion has been associated with inconsistent clinical
outcomes and significant complications. Posterior dynamic devices have been developed to …

Study Design. A cadaveric biomechanical study. Objective. To investigate the biomechanical
behavior of the cervical spine after cervical total disc replacement (TDR) adjacent to a …

Study Design. A biomechanical study using human spine specimens. Objective. To study
postural compensations in lordosis angles that are necessary to maintain horizontal gaze in …

MRI allows non‐invasive assessment of intervertebral disc degeneration with the added
clinical benefit of using non‐ionizing radiation. What has remained unclear is the relationship …

Study Design. In vitro biomechanical study. Objective. To quantify the effects of uncinatectomy
on cervical motion after total disc replacement (TDR). Summary of Background Data. The …

BACKGROUND CONTEXT: Total disc replacement (TDR) has been recommended to reduce
pain of presumed discogenic origin while preserving spinal motion. The floating core of …
