WHAT HAPPENS WITH A “HERNIATED DISC”？
椎间盘突出病症
As the spinal disc becomes less elastic, it can rupture.
随着椎间盘出现僵化，椎间盘会发生破裂。
When the disc ruptures, a portion of the spinal disc pushes outside its normal boundary this is called a herniated disc.
当出现破裂，部分椎间盘发生侧突，这被人们称之为椎间盘突出。
When a herniated disc bulges out from between the vertebrae, the spinal nerves and spinal cord can become pinched.
当椎间盘在椎骨间发生膨胀，脊神经和脊髓就会受到挤压。
There is normally a little extra space around the spinal cord and spinal nerves, but if enough of the herniated disc is pushed out of place, then these structures may be compressed.
通常来讲，脊髓和脊神经周边仍有少许空间，但如果椎间盘突出严重，这一结构将会受到压迫。
WHAT CAUSES SYMPTOMS OF A HERNIATED DISC?
椎间盘突出病因
When the herniated disc ruptures and pushes out, the nerves may become pinched.
当椎间盘发生破裂突出，脊神经将受到挤压。
A herniated disc may occur suddenly in an event such as a fall or an accident, or may occur gradually with repetitive straining of the spine.
如遇坠落或事故，椎间盘会突然出现突出，但也会因长期扭伤脊柱而发生突出。
Often people who experience a herniated disc already have spinal stenosis a problem that causes narrowing of the space around the spinal cord and spinal nerves.
通常，椎间盘突出患者有椎管狭窄症，该疾病指脊髓和髓神经周边空间狭窄。
When a herniated disc occurs, the space for the nerves is further diminished, and irritation of the nerve results.
当出现椎间盘突出，髓神经空间将进一步缩小，神经疼痛感随即产生。
WHAT IS A HERNIATED DISC? WHAT CAUSES IT?
什么是椎间盘突出？如何造成？
As described above, each disc of the spine is designed much like a jelly donut.
如上所述，每个椎间盘的设计原理就像果冻甜甜圈。
As the disc degenerates from age or injury, the softer central portion can rupture (herniate) through the surrounding outer ring (annulus fibrosus).
椎间盘会因外伤或年龄增长而出现退行性变，中间富于弹性的髓核会发生破裂，并在外环之处突出（纤维环）。
This abnormal rupture of the central portion of the disc is referred to as a disc herniation.
椎间盘中间部位的不正常破裂指的就是椎间盘突出。
The most common location for a herniated disc to occur is in the disc at the level between the fourth and fifth lumber vertebrae in the low back.
腰椎间盘突出症以下背部4-5节椎骨发病率最高。
This area is constantly absorbing the impact of bearing the weight of the upper body.
这片区域会持续承受上身负重。
This is especially important when we are standing or sitting.
当人们坐立时，下背部椎骨尤为关键。
The lower back is also critically involved in our body's movements throughout the day, as we twist the torso in rotating side to side and as we hinge the back in flexion and extension while bending or lifting.
下背部对人类日常活动尤为重要，扭动身体，弯腰或提举等伸展运动，这些都需要下背部。
WHAT ARE SYMPTOMS OF A HERNIATED DISC?
椎间盘突出症状
When the spinal cord or spinal nerves become compressed, they don't work properly.
当脊髓或脊神经受到挤压，它们无法正常工作。
This means that abnormal signals may get passed from the compressed nerves, or signals may not get passed at all.
受挤压神经或发出信号，或不发出任何信号。
Common symptoms of a hemiated disc include Electric Shock Pain.
椎间盘突出的普遍症状为电击痛。
