Posterior Epidural Migration of a Lumbar Intervertebral Disc Fragment Resembling a Spinal Tumor: A Case Report [PDF]

Annals of Rehabilitation Medicine, 2018
Posterior epidural migration of a lumbar intervertebral disc fragment (PEMLIF) is uncommon because of anatomical barriers. It is difficult to diagnose PEMLIF definitively because of its relatively rare incidence and the ambiguity of radiological findings

Wireless, Adaptable and Fully Implantable Battery‐powered Devices for Optical Stimulation of the Spinal Cord in Small Rodents

Advanced Science, EarlyView.
Current technologies for spinal cord optogenetic stimulation rely on external power sources and face reliability constraints in freely behaving animals. Here, a fully implantable, battery‐powered optoelectronic device is introduced, enabling operation in any selected environment with wireless recharging for months‐long stimulation.

Detrimental Effect of Low-Magnitude High-Frequency Vibration in an Ex Vivo Model of Intervertebral Disc Degeneration Despite Estrogen Treatment. [PDF]

JOR Spine
Low‐magnitude high‐frequency vibration (LMHFV), with or without 17β‐oestradiol (E2), exacerbated papain‐induced bovine intervertebral disc degeneration, reducing cell viability, impairing matrix production, and increasing inflammation. E2 showed no protective effect against papain‐induced degeneration or LMHFV.

Drug‐Induced Cuproptosis Defines the Therapeutic Window of Celecoxib in Intervertebral Disc Degeneration via the HSP90‐RBX1 Axis

Advanced Science, EarlyView.
This study reveals the dual role of celecoxib in intervertebral disc degeneration. While low concentrations are protective, high concentrations induce toxicity by upregulating HSP90, which synergizes with USP15 to deubiquitinate and stabilize RBX1. This leads to degradation of COMMD1/ATP7B, copper dyshomeostasis, and ultimately, cuproptosis.

Not all lumbar herniated discs cause low back pain

Horizonte Médico, 2017
After a long series of terms used to define the displacement of disc material (either the nucleus pulposus or the fibrous ring), herniated discs were classified as bulging, focal protrusion, extrusion and sequestration. Herniated discs represent from 1%

A Piezo‐Mimetic Ionic Hydrogel Harnessing Joint Motion for Cartilage Repair

Advanced Science, EarlyView.
A piezo‐mimetic ionic hydrogel converts mechanical deformation into bioactive ionic currents via stress‐induced asymmetric ion migration. Coupled with sustained Mg2+ release, this mechano‐electrochemical platform bridges mechanical loading and cellular signaling, enabling load‐adaptive stimulation and enhanced cartilage regeneration. ABSTRACT Articular
