Equine cervical intervertebral disc degeneration is associated with location and MRI features [PDF]

, 2019
Morphology of the equine cervical intervertebral disc is different from that in humans and small companion animals and published imaging data are scarcely available.

Newly identified intervertebral fat pad degenerates after intervertebral disc injury in a rat model of degeneration

Journal of Anatomy, EarlyView.
This study characterizes a newly‐described intervertebral fat pad (IVFP) anterior to rat IVDs, with evidence for its existence in mice and human IVDs as well. In rats, the IVFP gradually degenerated following IVD injury with changes in adipocyte size and fibrous tissue infiltration, suggesting it could play a functional role in IVD health and ...

Hydrogels for nucleus replacement: facing a biomechanical challenge [PDF]

, 2012
Hydrogels are considered promising for disc regeneration strategies. However, it is currently unknown whether the destruction of the natural interface between nucleus and surrounding structures caused by nucleotomy and an inadequate annulus closure ...

Postcranial anatomy of the Miocene hippopotamoids of Toros‐Menalla, Chad

Journal of Anatomy, EarlyView.
We establish a framework for the identification of postcranial remains in hippopotamoids by describing and comparing for the first time two late Miocene hippopotamoids from Toros‐Menalla, Chad (Hexaprotodon garyam, an early hippopotamid, and Libycosaurus bahri, the last African anthracothere) with the common hippopotamus.

Effect of pathology type and severity on the distribution of MRI signal intensities within the degenerated nucleus pulposus: application to idiopathic scoliosis and spondylolisthesis [PDF]

, 2010
Background Disc degeneration is characterized by a loss of cellularity, degradation of the extracellular matrix, and, as a result, morphological changes and biomechanical alterations.

Phenotypic characteristics of paroxysmal dyskinesia in 25 cats

Journal of Small Animal Practice, EarlyView.
Objectives Paroxysmal dyskinesia has, to date, been reported only systematically in Sphynx cats. This study aims to describe paroxysmal dyskinesia in additional breeds. Materials and Methods The medical records of cats from multiple hospitals presenting with episodes consistent with paroxysmal dyskinesia between 2020 and 2025 were retrospectively ...

MIS-TLIF for a gas-containing discal cyst with adjacent -lumbar spondylolisthesis: a case report and literature review

Frontiers in Surgery
IntroductionGas-containing lumbar disc cysts are a rare cause of neurogenic pain. These cysts typically occur in middle-aged and elderly patients and are predominantly associated with lumbar disc degeneration, presenting with sensory and motor deficits ...

Effect of Axial Load on the Flexural Properties of an Elastomeric Total Disc Replacement [PDF]

, 2012
Study Design. Twelve Cadisc-L devices were subjected to flexion (0°–6°) and extension (0° to -3°) motions at compressive loads between 500 N and 2000 N at a flexural rate between 0.25°/s and 3.0°/s.\ud \ud Objective. To quantify the change in flexural

Comparative Analysis of Three Vertebral Screw Placement Directions in Anterior Thoracolumbar Fracture Surgery: A Finite Element Study

Orthopaedic Surgery, Volume 17, Issue 5, Page 1464-1477, May 2025.
This study compares the biomechanical effects of three anterior fixation systems in thoracolumbar surgery—HXTL, NHXTL, and Medtronic's CD Horizon ANTERIOR. Finite element analysis evaluates stress and displacement across vertebral bodies and support structures under varying load conditions. Results indicate the HXTL system minimizes nail–rod stress yet
