Study Design. Seven different combinations of posterior screw fixation, with or without interbody
support, were compared in vitro using nondestructive flexibility tests. Objective. To study …

Study Design. A new anchored spacer—a low-profile cervical interbody fusion cage with
integrated anterior fixation—was compared biomechanically to established anterior cervical …

Object Unstable fractures at the thoracolumbar junction often require extended, posterior,
segmental pedicular fixation. Some surgeons have reported good clinical outcomes with short-…

Study Design. In vitro assessment of rib cage biomechanics in the region of true ribs with the
ribs intact then sequentially resected in 5 steps. Objective. To determine the contribution of …

Background context Novel dual-threaded screws are configured with overlapping (doubled)
threads only in the proximal shaft to improve proximal cortical fixation. Purpose Tests were …

Object An interspinous anchor (ISA) provides fixation to the lumbar spine to facilitate fusion.
The biomechanical stability provided by the Aspen ISA was studied in applications utilizing …

Introduction Sacroiliac (SI) joint pain has become a recognized factor in low back pain. The
purpose of this study was to investigate the effect of a minimally invasive surgical SI joint …

Study Design. A human cadaveric biomechanical study of 2 sacroiliac (SI) joint fusion implant
placement techniques. Objective. To evaluate and compare the biomechanical properties …

OBJECTIVE Lateral lumbar interbody fusion (LLIF) has emerged as a popular method for
lumbar fusion. In this study the authors aimed to quantify the biomechanical stability of an …

Object Posterior screw-rod fixation for thoracic spine trauma usually involves fusion across
long segments. Biomechanical data on screw-based short-segment fixation for thoracic fusion …
