Major spinal surgery procedure on a high cardiovascular risk patient with symptomatic neural compression due to 1: Osteoporotic T12 compression fracture along with 2—L5/S1 spondylolisthesis

Journal of Spinal Surgery, 2014
Introduction: Osteoporotic vertebral fracture most common located at thoracolumbar junction, whereas most spondylolisthesis at L4-5 is six to 10 times more frequent involved than adjacent level.

Prognostic Factors of Percutaneous Vertebroplasty for Vertebral Compression Fracture and Risk Factors of New Symptomatic Compression Fracture

Formosan Journal of Musculoskeletal Disorders, 2023
Background: Vertebral compression fractures (VCFs) are a common complication of osteoporosis and can lead to severe pain, decreased mobility, and reduced quality of life. Percutaneous vertebroplasty (PVP) is an effective minimally invasive procedure used

Buckling And Fracture Analysis Of Thick And Long Composite Cylinders With Cutouts Under Axial Compression: An Experimental And Numerical Campaign

, 2023
This article reports on the manufacturing, experimental testing, and finite element analysis of very thick and long carbon-fiber-reinforced polymers (CFRP) tubes under uniaxial compression (radius-to-thickness ratio ∼ 10 and length-to-radius ratio ∼ 21).

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Flexural Behavior of 3D‐Printed Porous Bouligand‐Structured Polymers: Influence of Pitch Angle and Porosity

Advanced Engineering Materials, EarlyView.
This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.
