Study Design. Pedicle screw pullout testing in osteoporotic and control human cadaveric
vertebrae, comparing augmented and control vertebrae. Objective. To compare the pullout …

Object Minimally invasive pedicle screws inserted vertically (that is, dorsoventrally) through
the pedicle, as opposed to the more common coaxial technique, offer potential advantages …

BACKGROUND CONTEXT: Researchers studying early pedicle screw designs have suggested
that pullout strength and insertional torque are correlated. For surgeons using pedicle …

Study Design. Cadaveric biomechanical study. Objective. To determine fatigue behavior of
cortical bone trajectory (CBT) pedicle screws. Summary of Background Data. Cortical bone …

Study Design. A biomechanical study was conducted to assess the stabilization performance
of transfacet pedicle screw fixation. Objective. To compare the biomechanical effects of …

This article reports the degradation and biological properties of as-drawn Mg–4Zn–1Sr (designated
as ZSr41) and pure Mg (P–Mg) wires as bioresorbable intramedullary pins for bone …

Background: Common suture configuration techniques used for ligament and tendon grafts
and repair are the Krackow locking stitch and a nonlocking loop stitch, such as a whipstitch. …

Study Design Biomechanical analysis. Objectives To show the role of additional rods and
long-term fatigue strength to prevent the instrumentation failure on three-column osteotomies. …

Study Design. In vitro biomechanical comparison of transarticular facet screws to lateral
mass plates in two level instrumentations of the cervical spine. Objective. Lateral mass plates …

Object The center (axis) of rotation (COR) in the lumbar spine has been studied well. However,
there is limited information on the kinetic and kinematic consequences of imposed shift in …
