Disc degeneration or trauma can cause the nucleus to herniate through the weakened layers of the outer disc and leak out of the annulus fibrosus into the spinal canal. 椎间盘退变或创伤会引起髓核从薄弱的椎间盘外层疝出,漏到纤维环之外...
橙色的为椎骨,白色的为椎间盘。 脊柱被分为了几个不同的区域(下图),其中腰椎的颜色为绿色,由L1-L5椎骨组成,位于下背部位置。腰椎由最强大的椎骨组成,因为它需要抵抗巨大的压力。腰椎的灵活性也更强(需要经常弯腰呀)。由于以上因素,腰椎也是最容易发生椎间盘突出的部位之一。 脊柱的中心部位(空心处)叫做椎管(spi...
In the case of a lumbar herniated disc, the weak spot in the annulus fibrosus is directly underneath the spinal nerve root, so a herniation in this area can put direct pressure on the nerve. 在腰椎间盘突出病例,纤维环的薄弱处正好在脊神经根深面,所以这个部位的椎间盘突出会直接压迫神经。 The ...
Causes(病因) Lumbar disc herniations are most frequently caused by degeneration due to the normal aging process. As small tears in the disc’s outer layer (annulus) develop and enlarge over time, the jellylike inner layer (nucleus)...

A lumbar disc herniation occurs in the lower back and commonly develops at the L4-L5 and L5-S1 spinal motion segments, located toward the base of the lower back.
The clinical herniated lumbar disc exsector comprises an operating handle and an exsector body, wherein the top end of the exsector body is fixedly connected with the operating handle, the bottom end of the exsector body is provided with a toothed cutting edge, the surface of the exsector...
Sciatica is a symptom frequently associated with a lumbar herniated disc. Pressure on one or several nerves that contribute to the sciatic nerve can cause pain, burning, tingling, and numbness that extends from the buttock into the leg and sometimes into the foot. Usually one side (left or ...
Magnetic resonance imaging (MRI) MRIis the gold standard imaging test to confirm a herniated lumbar disc as it provides the most accurate assessment of the location of the herniation and affected neural tissue. MRI is also the preferred test for surgical planning.1Al Qaraghli MI, De Jesus O...
