numbness, tingling, or weakness to radiate along the path of the nerve down the leg. However, many people have shown a herniated disc on MRI scans yet have no associated pain, so not all herniated discs will cause symptoms.
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 ...

腰椎间盘突出 Introduction(概述) A lumbar disc herniation, or lumbar radiculopathy, occurs when a small portion of a disc ruptures and causes pressure on spinal nerves. Small herniations are sometimes called bulges or protrusions, and...
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(spinal canal,下图左的空心部分)。脊...
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...

this study appears in: firstly, the use of the CycleGAN model based on convolutional layers to detect and classify the herniation type (median or foraminal) in lumbar intervertebral discs, secondly, the use of axial view MRI in order to classify the type of the herniated intervertebral disc. ...
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.
