Comparative analysis of endplate volumetric bone mineral density and endplate vertebral bone quality for predicting cage subsidence in lateral lumbar interbody fusion.

Objective: The aim of this study was to compare the predictive efficacy of quantitative CT (QCT)-based endplate volumetric bone mineral density (EP-vBMD) and MRI-based endplate vertebral bone quality (EBQ) score for cage subsidence (CS) after lateral lumbar interbody fusion (LLIF).

Methods: A retrospective study was conducted on patients who underwent single-level LLIF in conjunction with pedicle screw fixation at the authors' institution between January 2019 and April 2023. The volumetric bone mineral density (vBMD) was measured based on preoperative CT using phantom-less QCT software.

Anatomical Positional Variations of Retroperitoneal Organs and Lumbar Lordosis Angle Changes During Single-Position Prone Lateral Lumbar Interbody Fusion in Diverse Intraoperative Decubitus.

Study DesignRetrospective case series.ObjectiveThe single-position prone lateral lumbar interbody fusion (P-LLIF), which eliminates the need to change patient decubitus during the procedure, represents a modification of the traditional lateral lumbar interbody fusion (LLIF). This pioneering study aims to investigate the positional shifts of retroperitoneal organs and changes in lumbar lordosis angle across different decubitus, providing novel insights into the biomechanics of LLIF.

Multicolor and fast electrochromic P(DTB-EDOT)/ZnO nanocomposite film.

In this work, uniform and controllable size of ZnO nanoparticles were fabricated via solution-phase approach, and the copolymer based on the monomers of 1,4-di(thiophen-3-yl)benzene (DTB) and 3,4-ethylenedioxythiophene (EDOT) was successfully synthesized with electrochemical polymerization. A new P(DTB-EDOT)/ZnO nanocomposite film was obtained via situ preparation. Cyclic voltammogram and spectroelectrochemical characterization showed that the composite film had a stable and well-defined reversible redox process as well as electrochromic behavior.
