Aim. In this research, we aimed to study echographic characteristics and normal sizes of the vertebrae and intervertebral discs of the cervical region in healthy individuals.Materials and methods. On the material of 45 healthy volunteers, normal echographic characteristics of the cervical spine were studied using Toshiba Aplio 500 and Toshiba Aplio XG (Japan) scanners equipped with 3.5–5.0 MHz convex sensors and 7.5–12.0 MHz linear sensors.Results. It is found that ultrasound examination from the anterior-lateral access to the right and left allows the C3–C7 vertebral body surfaces facing the sensor to be visualized and their interposition and condition to be evaluated. A new echoanatomical reference point for ultrasonic identifi cation of the level of the cervical vertebra is proposed based on the visualization during the transverse scanning of the carotid artery bifurcation, which corresponds to the C3–C4 intervertebral disc level. The information capacity of the proposed echoanatomical criterion exceeds that for the traditional anatomical criterion used for the C7 vertebra along the sternoclavicular joint by 15.6 ± 5.4%. It is revealed that ultrasound examination provides for a satisfactory visualization of intervertebral discs at a level from C3–C4 to C7–Th1 in the longitudinal and transverse projections, as well as the evaluation of their echostructure and height measurement. The minimum, maximum and average values of the height of intervertebral discs at different levels are given; their dependence on gender, height and body weight of the examined persons is analyzed.Conclusion. It is established that ultrasound examination from the anterior-lateral access is an informative method for investigating vertebral structures at the C3–C7 level. The proposed echoanatomical reference point for C3 and C4 vertebrae allows the ultrasonic identifi cation of the cervical vertebra level to be improved by 15.6 ± 5.4%. The height of the intervertebral disc in healthy persons averages 4.38 ± 0.51 mm and signifi cantly nonlinearly increases from the C3–C4 to C7–Th1 level.

A 12-year-old, grey, crossbred pony mare was presented with a swelling in the neck over the area of the 2nd cervical vertebra (C2), which was found to be painful on palpation. The neck was held stiffly. Radiography of the cervical region showed a focal area of increased radio-opacity over the dorsal, caudal and lateral aspect of the dorsal spinous process of C2. Ultrasound confirmed the presence of a hypoechoic area approximately 15 cm in diameter superimposed over the dorsal spinous process of C2. An aspirate was taken of the mass, which revealed purulent exudate confirming the diagnosis of an abscess. The abscess was lanced with a scalpel blade and samples of the purulent material revealed a pure culture of Streptococcus equi subsp. equi. The guttural pouches (Eustachian tube diverticulae (ETD)) were then evaluated endoscopically and multiple chondroids were seen filling most of the right ETD. Surgery was subsequently performed and 189 chondroids were removed via a right-sided hyovertebrotomy. The ETDs were flushed and penicillin installed into both ETDs on 3 different occasions via a catheter introduced using a fibre optic scope. This procedure was repeated until a negative culture status was achieved in order to eliminate the carrier status.

Cervicogenic headache (CH) is a syndrome which is postulated to originate from nociceptive structures in the neck or head. The anatomical neck or head structures that are responsible for the pain in CH have not been clearly identified, but the pain in these patients probably originates from the structures of the cervical spine. In this study, cervical MRI were studied in 22 patients with cervicogenic headache and 20 control patients who did not have any disease which may effect the bone and muscle structures of cervical region. MRI imaging of cervical vertebra showed a disc bulging in 10 (45.4%) out of 22 patients with CH and in 9 (45.0%) of 20 controls ( P > 0.05). The distribution of pathological lesions in patients and controls were not significantly different ( P > 0.05). As a result, MRI may not be an adequate method to detect pathological findings underlying the aetiology of CH such as nerve roots, intervertebral joints and periosteum.

Background. Currently, there is no uniform tactics for the differentiated use of dorsal decompressive-stabilizing techniques for multilevel degenerative diseases of the cervical spine, and the results of these technologies application are largely controversial.Aim. Analysis of the unsatisfactory outcomes of dorsal decompressive-stabilizing interventions in the treatment of patients with multilevel degenerative diseases of the cervical spine and development of a clinicalinstrumental algorithm for differentiated surgical tactics.Material and methods. A retrospective study included 112 patients with degenerative diseases of the cervical spine at two levels or more due to hernias of intervertebral discs, yellow ligament hypertrophy and arthrosis of facet joints, which in 2007-2014 underwent dorsal decompressive-stabilizing interventions in the volume of laminotomy with laminoplasty (LP) and laminectomy with fixation for lateral masses (LF). A correlation analysis of clinical parameters with anamnestic data, instrumental parameters, a feature of accepted surgical tactics and postoperative adverse effects.Results. In the analysis, it was established that «satisfactory» postoperative outcomes of LP are associated with a neutral or lordotic configuration of the cervical spine, the preservation of segmental movements without clinical and instrumental signs of instability; In addition, the use of LF is possible with mobile kyphotization of the cervical spine and the presence of translational instability of the cervical segments. The «unsatisfactory» postoperative results of the LP and LF are in direct correlation with the duration of the disease, the presence of myelopathic focus and rigid kyphosis of the cervical region.Conclusion. Differential use of dorsal decompressive-stabilizing techniques based on a comprehensive assessment of disease duration, configuration of the cervical spine, spinal cord condition and volume of segmental movements allows to reduce neurological symptoms, improve the level of pain and improve the functional status of patients, as well as significantly reduce the number of adverse outcomes associated with the progression of kyphotic deformity, deterioration of neurological symptoms and revision on-line decompressive-stabilizing interventions.

Abstract Although qualitative descriptions of degenerative changes in the intervertebral disc components have been reported, methods to quantify these changes are lacking. A methodology was developed in this study to quantify the three-dimensional geometrical variations of the annulus fibrosus and nucleus pulposus. Fresh isolated intervertebral discs with adjacent vertebral bodies of skeletally mature young and old adult primates were sectioned sequentially, and different staining methods were used to distinguish the annulus and nucleus. Histological images were examined using light microscopy and exported to a computer to trace the boundaries of the annulus fibrosus and nucleus pulposus. Dorsal to ventral depth, medial to lateral width, and caudal to cranial height measurements of the nucleus pulposus and its relative location to the annulus pulposus were obtained. In the young adult, the nucleus was translucent with scattered notochordal cells. In the older adult, the nucleus appeared as a dense region of amorphous, irregular collagen material. A higher geometrical variation of nucleus due to degeneration was noted in the sagittal plane compared to coronal plane. Determination of the three-dimensional geometrical variations and histology analyses will assist mathematical modelers to better define the disc to study the biomechanics of the cervical spine.

A significant portion of the military population develops severe neck pain in the course of their duties. It has been hypothesized that neck pain is a consequence of accelerated degeneration of the intervertebral discs in the cervical spine, but more occupational and mechanistic-based tools and research are needed to positively confirm the link between neck pain and accelerated disc degeneration. Heavy head-supported mass including helmets and accessories worn by military personnel may subject the intervertebral discs of the cervical spine to complex cyclic loading profiles. In addition, some military operational travel which includes riding on high speed planing boats has also been reported to result in high magnitude cyclic loading on cervical spine discs. In this article, we present a methodology to computationally predict fatigue damage to cervical intervertebral discs over extended periods of time, by integrating kinematics-based biomechanical models with a continuum damage mechanics-based theory of disc degeneration. Through this computational approach, we can gain insights into the relationship between these military activities and possible accelerated fatigue degeneration of cervical intervertebral discs and provide a quantitative prediction tool for decade-long time ranges. The four significant improvements this computational framework adds to the area of modeling intervertebral disc degeneration are the following: (a) it addresses the non-linear nature of fatigue damage evolution, (b) it includes the effect of aging and damage recovery to accurately simulate biological phenomena, (c) it computes fatigue damage taking into account the multiaxial stress state in the disc, and (d) it correlates the computational damage parameter with established clinical grading systems for disc degeneration.

Musculoskeletal Anatomy

This study characterized the normal musculoskeletal anatomy of the cervical segment of the spine of dogs by means of B-mode ultrasonography. The objective was to establish the role of B-mode ultrasonography for the anatomical evaluation of the cervical spine segment in dogs, by comparing the ultrasonographic findings with images by computed tomography and magnetic resonance imaging. The ultrasound examination, in transverse and median sagittal sections, allowed to identify a part of the epaxial cervical musculature, the bone surface of the cervical vertebrae and parts of the spinal cord through restricted areas with natural acoustic windows, such as between the atlanto-occipital joint, axis and atlas, and axis and the third cervical vertebra. The images, on transverse and sagittal planes, by low-field magnetic resonance imaging, were superior for the anatomical identification of the structures, due to higher contrast between the different tissues in this modality. Computed tomography showed superiority for bone detailing when compared with ultrasonography. As for magnetic resonance imaging, in addition to the muscles and cervical vertebrae, it is possible to identify the cerebrospinal fluid and differentiate between the nucleus pulposus and annulus fibrosus of the intervertebral discs. Although not the scope of this study, with knowledge of the ultrasonographic anatomy of this region, it is believed that some lesions can be identified, yet in a limited manner, when compared with the information obtained mainly with magnetic resonance imaging. The ultrasound examination presented lower morphology diagnostic value compared with the other modalities.

Skeletal abnormalities in the upper cervical region may result in severe neck ache, altered mobility, muscular weakness and sensory deficits. Fused cervical vertebrae (FCV) have been reported in literature, however cases with fused articular facets have scarcely been documented. During routine osteology demonstration, we came across fused axis and the 3rd cervical vertebra. There was complete fusion of the vertebral arch on the left side along with complete fusion between the inferior articular facet of C2 and superior articular facet of C3. There was partial fusion between the bodies of the vertebrae and the right half of the vertebral arch. Owing to the vital role of this region in various neck movements and spinal alignment, knowledge of such asymmetric variations in the upper cervical region, is of immense importance to orthopedicians, radiologists, neurosurgeons, anaesthetists, physiotherapists.Keywords: intubation, synostosis, axis, block vertebrae

Objective. To analyze the effect of denervation of intervertebral discs in the cervical spine on the results of surgical treatment of patients with injuries to rotator cuff tendons of the shoulder joint.Material and Methods. Study design: descriptive hypothesis-generating study. The study included patients requiring surgical treatment of rotator cuff tear.  Two groups were identified: Group A included 28 patients who underwent plastic repair of rotator cuff tear with additional denervation of intervertebral discs, and Group B – 30 patients who underwent only plastic surgery for rotator cuff tear. The intensity of pain according to the VAS, functional activity due to neck pain (NDI), functionality of the shoulder joint (UCLA), and the degree of intervertebral disc degeneration according to MRI were assessed, and the effectiveness of treatment was determined. Statistical calculations were performed using the RStudio program.Results. In the group of patients with denervation of intervertebral discs, a more pronounced decrease in the intensity of pain syndrome at 3, 6, and 12 months (p < 0.001; p < 0.001; and p = 0.002), a more proportion of effectively treated patients at 3 months (p = 0.003), and significant increase in functional activity according to NDI at 3, 6 and 12 months of follow-up period (p < 0.001; p = 0.010; and p = 0.045) were observed.Conclusions. There is an underestimation of the role of degenerative cervical spine pathology in the occurrence of shoulder joint pain. In the case of rotation cuff plasty the additional denervation reduces the intensity of pain syndrome in the shoulder joint in the postoperative period.

Uncovertebral Joint

The uncovertebral joints appear in the adult human cervical spinal column. While the descriptions of this structure have been reported, methods to quantify the dimensions of these joints are lacking. Therefore, in this study a preliminary attempt was made to develop a methodology to quantify the three-dimensional anatomical details of these joints in the adult human cervical spine using sequential cryomicrotome anatomic sections. Bilateral dorsal to ventral length, medial to lateral depth, and caudal to cranial height measurements were obtained from C2-T1 levels. The well developed larger joints were observed in the mid to lower cervical (C3-C7) regions and the smaller joints were noted in the most cranial and caudal (C2-C3, C7-T1) levels. Uncovertebral joints in the mid to lower cervical region extended further ventrally compared to the most cranial and caudal levels. The height of the uncovertebral joints was equal to the lateral height of the intervertebral discs throughout the extent of the joint. The mean overall medial to lateral depth of the joint was 3.8 mm (± 1.8). These quantitative three-dimensional descriptions assist in describing uncovertebral joints in stress analysis based finite element models to understand its effects on the cervical spine biomechanical behavior.
