Adjacent Vertebral Refracture Prediction Model Based on Imaging Data After Vertebroplasty for Osteoporotic Vertebral Compression Fracture.

Objectives: To establish a predictive model to evaluate the risk of adjacent vertebral refracture (VRF) after percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture (OVCF) based on perioperative imaging data.

Methods: This study was a retrospective cohort study which established a predictive model of VRF after PKP for OVCF. Patients who underwent PKP for OVCF in our hospital between January 2018 and December 2020 were enrolled and divided into a refracture group and normal group.

Biomechanical study of anterior transpedicular root screw intervertebral fusion system of lower cervical spine: a finite element analysis.

The cervical anterior transpedicular screw (ATPS) fixation technology can provide adequate stability for cervical three-column injuries. However, its high risk of screw insertion and technical complexity have restricted its widespread clinical application. As an improvement over the ATPS technology, the cervical anterior transpedicular root screw (ATPRS) technology has been introduced to reduce the risk associated with screw insertion.

[Feasibility of a novel type of complex anterior cervical fixation by using Mimics software].

Objective: To investigate the feasibility of mimics software in analyzing a new type of complex anterior cervical fixation -- anterior transpedicular screw fixation+zero notch internal fixation.

Methods: From January 2021 to September 2022, 50 normal pedestrians who underwent cervical spine CT scanning were selected for C-C segment scanning, including 27 males and 23 females, aged from 25 to 65 years old with an average of (46.0 ± 9.

Risk Factors of Cage Subsidence Following Oblique Lumbar Interbody Fusion: A Meta-analysis and Systematic Review.

Objectives: The aim of this systematic review was to evaluate the risk factors for cage subsidence (CS) after oblique lumbar interbody fusion (OLIF).

Methods: The cohort and case-control studies which reporting potential risk factors for CS following OLIF were searched in PubMed, Embase, and Web of Science from database inception to June 17, 2023. Two researchers independently screened the literature, extracted data, and evaluated the quality of the literature according to the Newcastle Ottawa Scale.

Measurement of anatomical parameters of anterior transpedicular root screw intervertebral fusion system of cervical spine.

Objective: This study aims to investigate the feasibility of the anterior transpedicular root screw (ATPRS) intervertebral fusion system for the cervical spine and provide a basis for the design of the ATPRS intervertebral fusion system.

Methods: A total of 60 healthy adult cervical spine CT images examined from our hospital were selected, including 30 males and 30 females, with an average age of 39.6 ± 4.
