什么是ulnar神经麻痹？

Your ulnar nerve runs all the way from your shoulder to your little finger. The ulnar nerve manages the muscles that allow you to make fine movements with your fingers. It also controls some of the muscles of your forearm that allow you to grip things tightly. Unlike most of your other nerves, the ulnar nerve isn’t protected by muscle or bone throughout its course. In some areas, it’s near the surface of your skin. This means that injuries to the ulnar nerve aren’t uncommon.

当你在肘部击中有趣的骨头时，尺骨神经是创造了震荡的感觉。

你可能会失去感觉肌肉无力in your hand if you damage your ulnar nerve. This is known as ulnar nerve palsy or ulnar neuropathy. This condition can affect your ability to make fine movements and perform many routine tasks. In severe cases, ulnar nerve palsy can cause肌肉浪费或萎缩，使手看起来像爪子。手术有时需要纠正这一点。

Ulnar nerve palsy is typically a progressive condition, meaning it gets worse over time.

与尺神经麻痹有关的症状包括：

手中的缺乏力量会影响您的日常活动，例如抓住玻璃并握笔。

随着时间的推移，缺乏控制和感觉会导致手中的肌肉拧紧，导致爪状畸形。这通常只发生在严重的尺神经麻痹的情况下。

尺神经麻痹可以让它难以用手使用，因此可以更加努力地完成曾经容易的任务。将压力放在手上和下臂等高尔夫或网球的活动可能使疼痛变得更糟。

尺神经麻痹的原因并不是众所周知的。然而，由于以下：

  • 损害你的神经的疾病
  • an injury to the nerve
  • 对神经的过度压力
  • 由于肿胀导致的神经压力
  • 肘部骨折或错位

损坏尺神经是切割电话线。来自大脑的消息无法正确地传送到手臂和手臂上的目标，并且不能从手中接收。

Your doctor will first examine you and ask you about your symptoms. Make sure to tell your doctor if your symptoms began after an injury to your hand. This can help your doctor determine potential causes of your condition more easily. They’ll want to know how the injury occurred, how long symptoms have been present, and what makes your symptoms worse or better.

During the exam, your doctor will assess the condition of your hand and evaluate how well you can move your fingers.

In addition to a physical examination, testing can include:

These tests help detect swelling and measure nerve function in the ulnar nerve. They can also help to localize the area of the nerve that isn’t functioning properly. A nerve conduction study can help determine the severity of the dysfunction.

神经组织通常比其他类型的组织愈合得多。然而，一些ulnar神经麻痹症状可能会在没有治疗的情况下变得更好。

There are a number of possible treatments for ulnar nerve palsy, including:

  • 过度反击止痛药
  • 药物减少神经痉挛, such as gabapentin (Neurontin), carbamazepine (Tegretol), or phenytoin (Dilantin)
  • corticosteroids to reduce inflammation
  • a splint to support the handand reduce painful symptoms
  • physical therapy to increase muscle strength and function
  • occupational therapy to minimize further injury

Your doctor may also recommend surgery if the nerve damage is extensive, extremely painful, or not improving. Surgery is also often necessary if you find it difficult to go about your daily life due to the nerve palsy. If the cause of your ulnar nerve palsy is compressed nerve at the elbow, moving the nerve from the back of the elbow to the front of the elbow may be necessary.

如果您的医生确定神经不会恢复其正常功能，可能会推荐涉及肌腱转移的外科手术。在肌腱转移手术期间，一种功能肌腱从其原始骨附件移动到新的肌腱。这有助于恢复肌肉功能，允许您再次执行日常活动。

手术的结果通常很好，但神经慢慢愈合。完全恢复手腕和手动功能可能需要数月。即使在手术后，你仍然可能在手中失去感觉和运动。

Getting medical treatment as soon as you notice symptoms of ulnar nerve palsy is vital to preventing more serious complications, such as a permanent hand deformity. The most common cause is pressure on the nerve at the elbow. If the condition is progressive, then moving the nerve from the back of the elbow to the front takes pressure off the nerve and allows it to function normally.

如果您在第四和第五个手指中遇到刺痛，麻木或疼痛，请立即致电您的医生。您可能还想与职业治疗师见面，以确定您的日常工作习惯是否在ulnar神经上放置过多的压力。

To prevent further injury, you may need to wear a cast, splint, or brace for support.
