Tissue engineering has recently gained popularity as an alternative to autografts to stimulate
bone tissue regeneration through structures called scaffolds. Most of the in vivo experiments …

The present paper addresses femur failure mechanics, by numerically investigating the
influence of brittle/quasi-brittle bone constitutive description when combined with several …

Pedicle screw fixation is extensively performed to treat spine injuries or diseases and it is
common for thoracolumbar fractures. Post-operative complications may arise from this …

Three key factors are responsible for the biomechanical performance of pedicle screw
fixation: screw mechanical characteristics, bone quality and insertion techniques. To the best …

Background: To explore the biomechanical characteristics of 2 posterior bilateral pedicle
screw fixation methods using finite element analysis. Methods: A normal L3-5 finite element …

The management strategies of thoracolumbar (TL) burst fractures include posterior, anterior,
and combined approaches. However, the rigid constructs pose a risk of proximal junctional …

The present endeavour numerically exploits the use of a phase-field model to simulate and
investigate fracture patterns, deformation mechanisms, damage, and mechanical responses …

Background For the spinal internal fixation procedures, connecting rods to the pedicle
screws are commonly used in all spinal segments from the cervical to sacral spine. So far …

Screw loosening remains a prominent problem for osteoporotic patients undergoing pedicle
screw fixation surgeries and is affected by screw parameters (eg, diameter, pitch, and thread …

Metastatic lesions compromise the mechanical integrity of vertebrae, increasing the fracture
risk. Screw fixation is usually performed to guarantee spinal stability and prevent dramatic …
