Background Pedicle screws are widely used in fusion surgery, while screw loosening often
occurrs. An auxetic structures based pedicle screw was proposed to improve the bone …

Background Sacroiliac joint (SIJ) is a known chronic pain-generator. The last resort of
treatment is the arthrodesis. Different implants allow fixation of the joint, but to date there is …

One of the skeletal muscle's exceptional properties is its high damage tolerance in terms of
its high toughness, which allows the muscle to withstand cracks of millimeter length while …

Objective: To develop a methodology to improve the representation of the mechanical
properties of a vertebral finite element model (FEM) based on a new dual-energy (DE) …

Study design Computer biomechanical simulations to analyze risk factors of proximal
junctional failure (PJF) following adult scoliosis instrumentation. Objective To evaluate the …

The advances in health care and technological developments that facilitate human life have
increased longevity. As human life span has increased, the incidence of degenerative …

Aim of this study is to assess the pullout performance of various pedicle screws in different
test materials. Polyurethane foams (Grade 10 and Grade 40) produced in laboratory and …

Background Proximal junctional failure is a severe proximal junctional complication
following adult spinal instrumentation and involving acute proximal junctional kyphotic …

Background High rates of iliac screw fixation failures have been reported in spinopelvic
instrumentations. The objective was to assess the iliac screw loads as functions of …

In many spine surgeries, pedicle screws are commonly used to stabilize vertebrae, however,
loosening can be a complication. Different designs have shown improvements in fixation …
