Comparison of Adjacent Segment Degeneration After Nonrigid Fixation System and Posterior Lumbar Interbody Fusion for Single-Level Lumbar Disc Herniation: A New Method of MRI Analysis of Lumbar Nucleus Pulposus Volume

Journal of Investigative Surgery, 2018
Purpose: To evaluate the influence of a nonrigid fixation system and posterior lumbar interbody fusion on adjacent intervertebral disc degeneration by using MRI analysis of lumbar nucleus pulposus volume for single-level lumbar disc herniation. Materials

Establishing a Staging System for Adjacent Segment Disease and Exploring Its Significance in Guiding Surgical Decisions: A Retrospective Study

Orthopaedic Surgery, Volume 17, Issue 5, Page 1418-1432, May 2025.
Developed a staging system for adjacent segment disease based on degeneration characteristics. Verified the feasibility and reliability of stage‐guided surgical decision‐making through surgical data, radiological data, and follow‐up data. This staging system was closely correlated with intervertebral disc degeneration and disc height while also ...

Two‐Dimensional Electromagnetic Navigation‐Assisted Percutaneous Transforaminal Endoscopic Discectomy for Lumbar Disc Herniation: A Retrospective Comparative Study

Orthopaedic Surgery, EarlyView.
This study compares 2D versus 3D electromagnetic navigation‐assisted PTED for lumbar disc herniation. The 2D system significantly reduced surgical time, radiation exposure, and learning curve while maintaining similar clinical outcomes. It offers an efficient, safe, and practical alternative for less experienced surgeons.

Comparison Between Interlaminar and Transforaminal Endoscopic Lumbar Discectomy for Sciatic Scoliosis Secondary to Lumbar Disc Herniation: A Retrospective Study With a Minimum 1 Year Follow‐Up

Orthopaedic Surgery, EarlyView.
In this study, we aimed to evaluate and compare the clinical and radiographic outcomes of interlaminar endoscopic lumbar discectomy (IELD) and transforaminal endoscopic lumbar discectomy (TELD) in patients with lumbar disc herniation (LDH) with sciatic scoliosis, an area where evidence is limited and clinical decision‐making remains challenging ...

From senescence and inflammaging to systemic comorbidities: Drivers of aging‐associated periodontitis

Periodontology 2000, EarlyView.
Abstract Background Aging is accompanied by a chronic low‐grade inflammatory process, known as inflammaging, as well as immunosenescence, an age‐related decline and dysregulation of immune function, and cellular senescence, a process in which cells enter a state of irreversible growth arrest while actively releasing pro‐inflammatory factors.

Creation of an injectable in situ gelling native extracellular matrix for nucleus pulposus tissue engineering [PDF]

, 2017
Background Context: Disc degeneration is the leading cause of low back pain and is often characterized by a loss of disc height, resulting from cleavage of chondroitin sulfate proteoglycans (CSPGs) present in the nucleus pulposus.
