Bone Mineral Density Analysis for Evaluation of Cervical Vertebral Maturation
Objective: The cervical vertebral maturation (CVM) method is a useful tool for detecting the status of mandibular growth. However, the current CVM method based on two dimensional cephalometric radiographs may not fully include all factors that may be involved in bone maturation. For instance, the …

The effect of vasodilatation as obtained by lumbar sympathectomy on the growth of bones in normal young animals
… of this process has been observed in the upper cervical vertebrae in association with acute inflammatory lesions of the pharnyx and of the glands in the neck which may lead to osteoporosis of such a degree as to produce spontaneous fracture of a vertebra.

Development of a Fully Automated Al System for Skeletal Maturity Assessment Using Cone Beam CT
… look to biological markers, such as the cervical vertebrae and the spheno-occipital synchondrosis to perform such assessment, and automation of this process would greatly assist clinicians with both accuracy and efficiency in their daily practice. Our study seeks to develop, test, and …

Ultrasound imaging of cervical spine motion for extreme acceleration environments
… skeleton, but is not currently used to image the cervical spine, the injury of which may change the biomechanics of the cervical vertebrae, which CT and MRI (the current gold standard in cervical spine imaging) are poor at capturing. To validate ultrasound as a modality for imaging dynamic motion …

Segmentation of cervical and lumbar vertebrae in x-ray images using active appearance models and extensions
… algorithm tailored to the segmentation of cervical and lumbar vertebrae in digitized X-ray images. The algorithm employs the Generalized Hough Transform (GHT) to obtain a suitable initialization for two segmentation stages that utilize Active Appearance Models (AAMs) that were proposed by …

Assessment of fetoscopic tracheal occlusion using ultrasound images in phantom study
… is possible. There are many concerns about the cervical vertebrae stress and fetal distress that the hyperextension could cause to the fetus. The fetal neck positions throughtout the surgery were assessed and measured by means of ultrasound images. The results show that the babies undergo a neck …

A cadaveric and magnetic resonance imaging study of the anatomical variations of levator scapulae
… from the transverse processes of the first four cervical vertebrae (C1-C4) and inserts onto the superomedial border of the scapula. The main function of the levator scapulae muscle is to elevate the scapula. This study aimed to determine the morphometric variation in levator scapulae muscle and …

The Effect of Magnification Loupes on Posture During Instrumentation by Dental Hygienists
… of the head and trunk (occipital pole of head, cervical vertebrae: C5, thoracic vertebrae: T5, lumbar vertebrae: L1) to measure changes in posture. Accelerations in three axes were recorded (anterior/posterior (AP), medial/lateral (ML), vertical (VT)). Mean accelerations of the three axes were …

Potentiating effects of caffeine on the teratogenicity of acetazolamide in two strains of mice
… Skeletal examination of the number of ossified cervical and caudal vertebral centra revealed a reduction in ossification among C57BL/6J litters exposed to high dose acetazolamide or acetazolamide plus caffeine. These same centers of ossification were mildly affected by treatment in the SWV …

Mobility and hydrodynamic implications of the long neck in plesiosaurs
… digital manipulation of an ostrich neck. Neck vertebrae from the posterior-most half of an ostrich neck were manipulated to determine dorsoventral and lateral RoM at successive stages of dissection. Neck vertebrae from four plesiosaur specimens were digitised to study RoM, and showed …

3D mathematical model of the hyoid bone and attached muscles during swallowing
… (UES) and the antero-inferior corner of cervical vertebrae 7 (C7) were also measured. The soft tissue between the hyoid bone and the anterior UES boundary was denoted as TH; the soft tissue between the posterior boundary of UES and C7 was denoted as RF. Then, using a lambda model treating …

Exploring the visualisation of the cervicothoracic junction in lateral spine radiography using high dynamic range techniques
… removal of the shoulder girdle in order for the cervical vertebrae to be imaged separately. HDR was explored for single and dual-energy X-ray images of the phantom. In the case of single-image HDR, the HDR image of the phantom without water was constructed by combining images created with varying …

Effectiveness of Thermal Oxidation in Relation to Anterior Cervical Plates
Ti-6Al-4V anterior cervical plates (ACP) are used in spinal fusion surgeries to fixate cervical vertebrae during graft adhesion. However, documented cases of implant failure and the potential for ACP corrosion raise concerns regarding any degradation of material resulting from extended …

Comparison of passive cervical spine flexion in children and adults
… biomechanics, this study compared the passive cervical spine flexion of children to adults in specific age groups (6-8, 9-12, 20-29, 30-40 years). Subjects with restrained torsos and lower extremities were exposed to a 1 g inertial load in the posterior-to-anterior direction, such that the …
