Contribution of injured posterior ligamentous complex and intervertebral disc on post-traumatic instability at the cervical spine

Computer Methods in Biomechanics and Biomedical Engineering, 2020
Posterior ligamentous complex (PLC) and intervertebral disc (IVD) injuries are common cervical spine flexion-distraction injuries, but the residual stability following their disruption is misknown.

Therapeutic Implants: Mechanobiologic Enhancement of Osteogenic, Angiogenic, and Myogenic Responses in Human Mesenchymal Stem Cells on 3D‐Printed Titanium Truss

Advanced Healthcare Materials, EarlyView.
This study investigates a synergistic effect between 3D‐printed surface features and mechanical micro‐strain in enhancing the osteogenic, angiogenic, and myogenic responses of human mesenchymal stem cells (hMSCs). Load‐induced mechanotransduction, facilitated by the implant's architectural design, significantly amplifies hMSC differentiation.

Dynamic Lumbosacral Magnetic Resonance Imaging in a Dog with Tethered Cord Syndrome with a Tight Filum Terminale [PDF]

, 2017
A 1-year and 11-month- old English Cocker Spaniel was evaluated for clinical signs of progressive right pelvic limb lameness and urinary incontinence. Neurological examination was suggestive of a lesion localized to the L4–S3 spinal cord segments.

Structure, Mechanics, and Mechanobiology of Fibrocartilage Pericellular Matrix Mediated by Type V Collagen

Advanced Science, EarlyView.
This study defines the structure, mechanics, and mechanobiology of the fibrocartilage pericellular matrix (PCM) using the murine meniscus, showing how collagen V deficiency alters PCM properties and disrupts cell mechanosensitive signaling. Findings emphasize the critical role of PCM in fibrocartilage mechanobiology and suggest targeting it can enhance

LUMBAR ENDOSCOPIC PERCUTANEOUS DISCECTOMY - CLINICAL OUTCOME. PROSPECTIVE STUDY

Coluna/Columna
Objective: Lumbar disc herniation is a common indication for surgical treatment of the spine. Open microdiscectomy is the gold standard. New surgical techniques have emerged, such as spinal endoscopy.

The effect of intervertebral cartilage on neutral posture and range of motion in the necks of sauropod dinosaurs [PDF]

, 2013
The necks of sauropod dinosaurs were a key factor in their evolution. The habitual posture and range of motion of these necks has been controversial, and computer-aided studies have argued for an obligatory sub-horizontal pose.

Identifying Myeloid‐Derived Suppressor Cells and Lipocalin‐2 as Therapeutic Targets for Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Inflammatory dysregulation drives intervertebral disc degeneration via stage‐dependent immune cellular dynamics. Single‐cell transcriptomics and genetic risk mapping revealed a shift from LCN2high myeloid‐derived suppressor cells maintaining disc repair in early stages to IL1B+ macrophage‐dominated pathology in advanced disease.
