The impact of transportation infrastructure on bicycling injuries and crashes: a review of the literature
TLDR
Evidence is beginning to accumulate that purpose-built bicycle-specific facilities reduce crashes and injuries among cyclists, providing the basis for initial transportation engineering guidelines for cyclist safety. Expand
Route infrastructure and the risk of injuries to bicyclists: a case-crossover study.
TLDR
The lower risks on quiet streets and with bike-specific infrastructure along busy streets support the route-design approach used in many northern European countries. Expand
Hip protectors: recommendations for biomechanical testing—an international consensus statement (part I)
TLDR
An evidence-based consensus statement from the International Hip Protector Research Group on recommended methods for evaluating the biomechanical performance of hip protectors is presented. Expand
During sideways falls proximal femur fractures initiate in the superolateral cortex: evidence from high-speed video of simulated fractures.
TLDR
This cadaveric model of hip fracture empirically confirms hypotheses that suggested that hip fractures initiate with a failure in the superior femoral neck where stresses are primarily compressive during a sideways fall impact, followed by a failure on the inferior neck where pressures are primarily tensile.

Biomechanical Evaluation of the Total Facet Arthroplasty System™: 3-Dimensional Kinematics
TLDR
The TFAS allowed considerable motion in all directions tested, with ROM being less than the intact in flexion and lateral bending, and greater than the damaged spine in axial rotation, and the helical axis of motion was shifted anteriorly inAxial rotation. Expand
In vitro axial preload application during spine flexibility testing: towards reduced apparatus-related artefacts.
TLDR
Four distinct types of preload which have roots in contemporary experimental practice are quantitatively compared, whereby unwanted moment can only be prevented at the cost of shear force production. Expand
Compressive strength of interbody cages in the lumbar spine: the effect of cage shape, posterior instrumentation and bone density
TLDR
In vitro biomechanical investigation of the compressive behaviour of three different interbody cage designs in a human cadaveric model suggests that failure of the bone-implant interface may occur clinically. Expand
Proximal femur bone strength estimated by a computationally fast finite element analysis in a sideways fall configuration.
TLDR
A method to quickly and accurately estimate proximal femur structural stiffness and failure load using QCT-driven FE methods that took less than 11 min to solve using a standard desktop workstation is developed and validated. Expand
Kinematic response of lumbar functional spinal units to axial torsion with and without superimposed compression and flexion/extension
TLDR
Information on the kinematic response to axial torsion with superimposed axial compression, compression-flexion and compression-extension was investigated in 10 cadaveric lumbar functional spinal units and may find application to identifying indications for spinal fusion or in evaluating the effect of future semi-flexible instrumentation. Expand
A Method to Simulate In Vivo Cervical Spine Kinematics Using In Vitro Compressive Preload
TLDR
Three-dimensional flexibility test moments needed to obtain spinal kinematics representative of the in vivo spine studies are determined and the 2:4:2 protocol resulted in significantly better agreement with in vivo data than did the 1:1:1 protocol. Expand
