Abstract

Jingling is a major risk factor contributing to the development of cervical spondylitis. Several acute and chronic conditions can occur, starting with neck pain and progressing to cervical radiculopathy. Ultimately, the degenerative cascade causes disc desiccation and loss of height along the ventral border of the cervical spine. This causes ventral angulation and eventual loss of lordosis with compression of neural and vascular structures. The altered posture of the cervical spine progresses to kyphosis and persists until load balance and lordosis are restored. The content of this paper addresses the physiological and biomechanical pathways leading to cervical spondylosis and the biomechanical principles associated with surgical correction and management of kyphosis progression.

Introduction

Cervicitis is a common progressive degenerative disease of the human spine, often caused by the natural aging process. Because of the osteophyte formation that accompanies the progressive degeneration of the vertebral segments, it is defined as vertebral osteophyte secondary to degenerative disc disease. Early spondylitis is associated with degenerative changes within the intervertebral disc that result in desiccation of the disc, resulting in a global loss of disc height and the disc sustaining or supporting additional axial load along the cervical spine  [1].

At birth, the intervertebral disc is healthy, and the proteoglycan matrix within the nucleus pulpous maintains water content of 70% to 90%, which decreases with age. As the water content within the nucleus decreases, the once healthy, shiny, gelatinous appearance changes to a dark, discoloured, fibrous "crab meat" consistency with loss of water content and loss of structural integrity. As the disc begins to degenerate and the disc loses height, the soft tissues ligaments and disc loosen, causing the disc to bulge at the ventral and/or dorsal margins of the disc and kinking the ligaments around the spinal segment  [2].

This is affected by the capillary diameter and the properties of the chemicals used. By introducing counter flow, hydrodynamic long-term measurements are possible. The flow rate is set equal to the final velocity of the bubble rise and held in place. Increasing the capillary diameter increases the rising velocity and changes the wake structure behind the bubble. These wake structures can be visualized by particle imaging velocimetry, in which fluorescent particles are dispersed in a liquid phase. In steady flow, particles follow the streamlines of the flow and can be tracked by evaluating the tracer particle ensemble from a series of time-accurate images. Additional laser-induced concentration fields around bubbles Fluorescence measurement this can be done by adding a dye whose fluorescence is quenched on contact with gas moving into the liquid phase. Furthermore, a coordinated chemical reaction system can be applied to visualize local mass transfer via colour change reactions. All of these techniques have strengths and weaknesses, but they are all limited to optically accessible systems and rely on tracers or chemicals that contaminate the system under study [3].

Reduced disc height Structural and mechanical integrity that supports the soft tissues throughout the neck. A compromised ventral strut results in greater axial load transmission along the spinal facet joints and dorsal struts, resulting in greater loads carried by the facet joints. Increased axial load redistribution along the dorsal cervical spine leads to overloading of the facet joints, leading to hypertrophic facet joints with possible prolonged ossification of the posterior longitudinal ligament. Cervical myelopathy includes motor and reflex changes indicative of a more chronic condition, ultimately resulting in spastic weakness and numbness in the extremities, loss of dexterity, spastic gait, loss of spinal function, and pain .These chronic conditions have a poor prognosis and may eventually become permanent  [4].

Pathogenesis and Aetiology of Cervical Spondylosis:

The main cause of cervical spondylosis is age-related degeneration. However, there are some exceptions where disc injury may amplify the degenerative process in young patients. Secondary manifestations of spondylosis are decreased disc height and vasculature and vasculature caused by osteophyte impingement. Associated with compression of nerve structures. It is this physiological degenerative cascade that contributes to biomechanical changes that can lead to nerve and blood vessel compression, pain, and loss of function. The sequence of events in cervical spondylosis, beginning with biomechanical changes that can lead to compression of nerves and blood vessels. Ventral angulation along the cervical spine is a sequential cascade of mechanical events. As the lordosis angle decreases, the moment arm about the centre of rotation or instantaneous axis of rotation increases, changing the global sagittal angle and decreasing the diameter of the spinal canal [5].

Conclusion

This simulation model indicates that the stress distribution is wider in the diffusion type than in the central and lateral types, thus the symptoms of the diffusion type CSM may be more severe than those of the central or lateral type CSM. I have a more careful follow-up of anterior spinal cord compression is recommended if the resulting form is of the diffuse type.
