Summary: The aberrant cervical count in tree sloths seems to have some impact on the rotational ability of their necks, but it plays a secondary role in overall neck mobility. The rotational capacity of the neck is primarily determined by the anatomy of the vertebrae.

Summary: This study evaluated the subchondral bone mineral density (sBMD) of cervical endplates using CT-OAM and its correlation with mechanical implant subsidence in a cadaveric model. The results showed that denser endplates experienced less deformation under the same load. The study validated the use of CT-OAM as a method to analyze sBMD, providing new tools for clinicians treating spinal conditions.

Summary: This study proposes the use of deep learning models for estimating cervical vertebral maturation from lateral cephalograms, and introduces a stepwise segmentation-based model. The results show that the three-step segmentation-based model achieved the best accuracy compared to non-segmentation-based models.

Summary: The study aimed to evaluate the biological function of cervical subtotal discectomy prosthesis (CSDP) implantation in a non-human primate model. The results demonstrated that CSDP had excellent cytocompatibility, osseointegration capacity, and biomechanical stability in non-human primate models, suggesting its potential application in the treatment of cervical disc diseases.

Summary: Retrospective radiological analysis revealed that HU values vary among different levels of the cervical spine and the distribution within the vertebrae is not homogeneous. Decreased vertebral bone mineral density and osteoporosis may trigger or exacerbate adjacent intervertebral disc degeneration.

Summary: Individuals with type 2 diabetes mellitus have an increased risk of fragility fracture despite normal to high bone mineral density. This study investigates the effect of type 2 diabetes mellitus on microdamage quantity and morphology in cancellous bone and relates it to cancellous microarchitecture. The results suggest that cancellous microarchitecture does not explain fracture risk in type 2 diabetes mellitus, indicating alterations in material matrix properties as a potential mechanism.

Summary: This study compares the use of murine cervical vertebrae and lumbar vertebrae for assessing osteoporosis. The results show that the cervical spine is more suitable for early-stage evaluation of osteoporosis, with earlier bone loss and worse mechanical properties.

Summary: Segmentation of the cervical spine and cranial bones using X-ray images is crucial for diagnosing TAOD. Previous studies have limited segmentation to only parts of the cervical spine and have not included cranial bone segmentations. This study trained a U-Net model to automatically segment important features for diagnosing TAOD, achieving high accuracy as measured by accuracy and dice coefficient values.

Summary: This study investigated the biomechanical properties of human neurocranial bones across a wide age range, revealing correlations with age, location, and thickness. The study found that sex-related differences in biomechanical properties require further investigation.

Summary: This study investigated the tissue mineral density (TMD)-dependent elastic modulus of individual trabeculae and found significantly higher TMD and tissue modulus in trabecular plates than in rods. Axial tissue modulus was consistently higher than lateral tissue modulus regardless of trabecular type and orientation, with axial correlation predicting higher tissue modulus than lateral correlation at the same TMD level.

Summary: A novel motion-preserving artificial cervical disc and vertebra complex has been designed to reduce adjacent segment disease (ASD) by minimizing the range of motion and stress of adjacent discs. Biomechanical tests showed that the designed complex provided physiological mobility and stability, reduced compensatory motion of adjacent intervertebral discs, and alleviated stress changes of adjacent discs.

Summary: The neck is a critical part of the avian spine, enabling birds to manipulate their surroundings. It displays a high level of diversity across different anatomical scales. Despite this, little is known about the factors driving this variation and the role of neck evolution in avian macroevolution. This review explores the development, function, and evolution of the avian cervical spine, highlighting the need for further research to broaden our understanding of this important structure.

Summary: The tails of non-avian dinosaurs vary greatly in length and form, with no consistent relationship between tail length and snout-sacrum length. Different groups of dinosaurs exhibit varied patterns of centra lengths along the tail, but many show a pattern of short centra followed by longer ones. This pattern is believed to be functionally important and may have evolved independently in different dinosaur groups.

Summary: This study measured and analyzed the microstructures and morphometric parameters of the cervical facet using high-resolution 3D micro-computed tomography. It revealed that the cervical facet has complicated 3D microstructures and inhomogeneities, and correct identification and evaluation of its microstructure can help in the diagnosis of orthopedic disease and predict early phases of fracture risk.
