The hemisection damages neural tracts in the spinal cord that carry information to and from the brain.

这种半切损伤了髓中为大脑传递信息的束。

So, suppose a person was stabbed in the neck, and had a complete right hemisection of the spinal cord.

现假设一名患者被刺伤了颈部，彻底损伤了右侧髓。

Now, in clinical scenarios, a complete right side or complete left side hemisection is pretty rare.

床上，完全的右侧或完全的侧半切损伤是非常罕见的。

Brown-Sequard Syndrome is a condition associated with hemisection of spinal cord, which usually damages descending corticospinal tracts, ascending dorsal column tracts and spinothalamic tracts.

髓半切综合征，是一种与髓半切损伤相关的疾病，通常会损伤下行的皮质髓束、上行的髓背侧束与髓丘脑束。

That's why, most of the time, individuals with Brown-Sequard Syndrome will only present with an incomplete hemisection, and some sensory or motor problems, depending on which tracts are damaged.

这就是为什么大多数情况下，髓半切综合征患者仅表现出不完全的半切损伤，即根据受损束而不同的部分感觉和运动症状。

In Brown-Sequard syndrome, a vertebral bone fracture or any kind of penetrating trauma, like a gunshot injury or stab wound in the back can lead to the hemisection of the spinal cord.

髓半切综合征，即椎骨折或有任何穿透性创伤，比如火器伤、背部刺伤，造成髓半侧损伤的情况。

Besides those three tracts, very rarely, a hemisection of the spinal cord above the T1 spinal level can also damage the sympathetic chain that runs alongside the spinal cord and supplies the facial region.

很罕见的情况下，除了上述三条束，髓胸1水平以上的半切损伤还会损伤沿髓走行、支配对应面部区域的交感。
