A: The so-called degradation is an aging phenomenon. After 30 years old, especially in old age, the body, internal organs, shape and function will gradually become aging and degenerate, and the motor system will also degenerate with aging. Cervical degeneration can be manifested as cervical marginal degeneration, hyperosteogeny, increased brittleness, decreased elasticity of joint capsule, cervical intervertebral disc degeneration and so on. These conditions will compress and stimulate nerves, blood vessels or spinal cord, and eventually lead to cervical spondylosis. Four questions: Why does acute cervical spine injury cause cervical spondylosis?
A: For the whole spine, the cervical spine has the largest range of motion, and it also bears the gravity and activity of the head. Cervical trauma can lead to different types of cervical spondylosis if it is caused by head collision, sprain and extrusion. About 12% ~ 20% of patients with cervical spondylosis have a history of acute trauma, especially cervical fracture, bleeding after dislocation, edema spreading to intervertebral foramen, and displacement of fracture fragments directly compressing nerve roots or spinal cord. Cervical disc injury caused by various reasons is also an important cause of cervical spondylosis. Five questions: Why does inflammation cause cervical spondylosis?
A: Being caught cold by wind, especially being invaded by wind, cold and humidity for a long time, can lower the pain threshold of nape back, cause long-term chronic pain of nape back, or cause chronic myofibrositis of nape back. Long-term anti-pain muscle tension will increase the internal pressure of cervical joint and promote joint aging.
