Analysis of the Justification for Spinal Computed Tomography (CT) Scans Performed in Togo

Journal of Medical Radiation Sciences, Volume 72, Issue 4, Page 490-496, December 2025.
The undeniable benefits of irradiating examinations such as CT scans should not overshadow their potential harmful effects, particularly late risks. Hence it is important to justify CT scans requested for patients. This study revealed that a significant number of spinal CT scans performed in developing countries such as Togo were not a priori justified,

Glenosphere Tilt and Size Predict Shoulder Kinematics During the Hand‐to‐Back Motion After Reverse Shoulder Arthroplasty

Journal of Orthopaedic Research, Volume 43, Issue 12, Page 2080-2092, December 2025.
ABSTRACT Internal rotation (IR) is not reliably improved after reverse shoulder arthroplasty (RSA). This study aimed to identify surgical parameters that predict kinematics of the hand‐to‐back motion (H2B) after RSA and to identify associations between kinematics and clinical outcomes after RSA.

Simulating Federated Learning to Enable Multi‐Hospital Collaboration for Lumbopelvic Alignment Estimation

JOR SPINE, Volume 8, Issue 4, December 2025.
Federated learning (FL) effectively estimates lumbopelvic parameters from multi‐center spinal imaging, matching centralized methods' accuracy while preserving patient privacy, highlighting FL's potential to enhance diagnostic precision and broaden AI‐driven clinical applications in spine care without compromising data confidentiality.

Age and Spinal Level as Predictors of Lumbar Disc Degeneration in Humans and Mice: A Comparative Analysis

JOR SPINE, Volume 8, Issue 4, December 2025.
Mouse models are commonly used to study IVD degeneration and related neurological conditions that especially impact elder population. However, how well mice replicate human pathology remains unclear. This study compared lumbar IVD degeneration patterns across age and spinal levels in humans and mice.

Reduced Shear Modulus and Altered Lamellar Morphology of the Outer Annulus Fibrosus in Painful Intervertebral Disc Degeneration Compared With Tissue From Non‐Surgical Controls

JOR SPINE, Volume 8, Issue 4, December 2025.
Disc degeneration (DD) results in a mechanically dysfunctional disc through progressive loss of the intervertebral disc's (IVD) highly organized structure. This study measured shear and structure properties of the outer annulus fibrosus in surgical DD and minimally degenerative (non‐DD) donor individuals.

Single‐Side Iatrogenic Pedicle Injury May Trigger an Increased Risk of Contralateral Screw Loosening: An In Silico Study

JOR SPINE, Volume 8, Issue 4, December 2025.
ABSTRACT Background Screw loosening is a frequently reported complication following pedicle screw fixation, resulting in various adverse outcomes. The primary trigger for screw loosening is biomechanical deterioration. Iatrogenic injury to the pedicle is a commonly observed scenario.

High‐Resolution 3‐Dimensional Micro‐CT Imaging of Intervertebral Discs Using a Novel Contrast Agent

JOR SPINE, Volume 8, Issue 4, December 2025.
This study introduces the first use of a contrast agent (potassium iodide) to enhance 3D imaging of the nucleus pulposus within an intact intervertebral disc (IVD). This method was used to demonstrate consistent 3D imaging of the nucleus pulposus across multiple animal models, including spine and tail IVDs.

Injury Induces More Severe Biomechanical Changes in Middle‐Aged and Geriatric Lumbar Spines in a Mouse Ex Vivo Model

JOR SPINE, Volume 8, Issue 4, December 2025.
Injury and age exhibited an interactive effect, resulting in greater biomechanical dysfunction in middle‐aged (12 months) and geriatric (24 months) mouse intervertebral discs (IVDs), associated with age‐related proteoglycan loss and collagen denaturation as shown by FTIR and histological analyses.

The Impact of the Ovine Annular Lesion Model on IVD Pathobiology and Utility of the Ovine Spinal Model in Patho‐Anatomical Studies: A Historical Perspective

JOR SPINE, Volume 8, Issue 4, December 2025.
The ovine annular rim‐lesion model of intervertebral disc degeneration of Osti and colleagues (1990) has evolved into a sophisticated mechanical destabilization large animal model of intervertebral disc degeneration over its 35 year history offering diverse musculoskeletal multi‐disciplinary investigations into the multifunctional complexity of this ...
