正常情况下,脊髓终于腰1 、腰2水平,此处,脊髓呈倒置的锥形,称脊髓圆锥。其下方的腰骶椎管内,丛多细小的神经如马的尾巴一样,故称为马尾。马尾神经受压可产生双下肢及大小便功能障碍,称为马尾神经综合征。

正常情况下,脊髓终于腰1 、腰2水平,此处,脊髓呈倒置的锥形,称脊髓圆锥。其下方的腰骶椎管内,丛多细小的神经如马的尾巴一样,故称为马尾。马尾神经受压可产生双下肢及大小便功能障碍,称为马尾神经综合征。

  Cauda equina syndrome occurs when the cauda equina, a bundle of nerve fibers at the bottom of the spinal cord, becomes irritated by pressure or inflammation.

  当马尾神经,脊髓以下的一束神经纤维因受压或炎症刺激,会发生马尾神经综合征。

  The spinal cord runs from the base of the skull to the top of the lumbar spine, where it splits into a bundle of nerve root branches called the cauda equina.

  脊髓走行于颅底直到腰椎顶部,并在此处发出一束神经根丛,称为马尾神经。

  The individual nerves in this part of the spinal cord exit through small holes in the lumbar spine called foramina, and run downward through the sacrum, to the legs and feet.

  从这段脊髓发出的各条神经在腰椎称为椎间孔的小孔处穿出,或下行从骶骨穿出,到达腿和足部。

  The nerve fibers of the cauda equina communicate sensory and motor nerve messages between the central nervous system and the pelvis and lower limbs. They are responsible for control and sensory function of the bowel and bladder, genitals and saddle area, and the nerves that run down the legs.

  马尾神经的神经纤维在中枢神经系统与盆腔和下肢之间传递感觉和运动信号,负责直肠和膀胱、生殖器和鞍区的控制和感觉,并有神经向下支配到腿。

  Any lumbar spine condition that compresses the nerves of the cauda equina can cause cauda equina syndrome.

  一些压迫马尾神经的腰椎疾患会引起马尾神经综合征。

  Often, it is a massive disc herniation that causes the syndrome. Other causes include spinal stenosis, inflammation or infection within the spinal canal, tumors, or injury to the spine.

  引起马尾神经综合征最常见的是巨大的椎间盘突出。其它原因包括椎管狭窄,椎管内炎症或感染、肿瘤,以及脊柱外伤。

  The symptoms of cauda equina syndrome will vary depending on which nerves are affected and the degree of nerve compression and subsequent irritation.

  马尾神经综合征的症状根据哪些神经受累及神经压迫及继发激惹的程度不同而异。

  These symptoms include severe low back pain, and neurological problems in the saddle region and lower limbs that may include urinary or bowel incontinence, loss of feeling, motor weakness, or loss of motor function in the legs such as difficulty walking.

  这些疼痛包括严重的腰痛,鞍区和下肢的神经症状包括大小便失禁、感觉缺失、运动无力或下肢运动功能障碍,例如行走困难。

  Though rare, acute cauda equina syndrome is a serious medical emergency. It usually requires decompression surgery on the spine within 24 hours, in order to remove pressure from the nerves.

  尽管罕见,急性马尾神经综合征是严重的医学急症。通常需要在24小时内进行外科手术减压,以解除对神经的压迫。

  Acute cauda equina syndrome that results in nerve damage is rare. However, if left untreated, cauda equina syndrome can result in paralysis, loss of sensation below the lumbar spine, and permanent loss of bladder and bowel control.

  急性马尾神经综合征导致神经毁损较少,但如果不及时治疗,马尾神经综合征会导致瘫痪、腰椎以下感觉缺失以及永久性大小便失控。
