Is a Funny Bone a Bone

What'southward so funny about the funny os? Really, null. This is what you rapidly conclude if yous accidentally hitting just the right spot on your elbow. All of a sudden, a shocking, tingling pain shoots right down your elbow, into your mitt.

It isn't even a os you've hit. It's actually a nerve. Specifically, the ulnar nerve. This nerve, one of the three main nerves in the arm, runs from the neck surface area and extends to the mitt. The ulnar nervus innervates muscles of the forearm, hand and two fingers (the ring and pinky fingers). Information technology is believed to take been named the "funny bone," because the nerve corresponds to the humerus os (which sounds like humorous, as in funny). It is also speculated that the term comes from the "funny" feeling of hitting it.

How can a gentle tap cause such a severe reaction? At its most vulnerable spot, the ulnar nerve passes through a channel called the cubital tunnel. It is there that protection is express to only a thin coating of skin and minimal fat.

Typically, when you hit the ulnar nervus, y'all give it 30 seconds, milkshake your arm around and that fleetingly pain goes away. Just, what happens when it'due south more than a temporary feeling? Prolonged pain, numbness or tingling can exist caused by an injury or overuse. In rare incidents, mayhap a tumor. It is the upshot of nervus irritation, inflammation or ulnar nervus entrapment.

What is ulnar nervus entrapment?

Ulnar nervus entrapment ensues when the nerve is compressed or pinched. Although information technology can occur in the forearm or manus, the most common site of ulnar nerve entrapment is at or near the elbow, especially in the region of the cubital tunnel. When pinch of the ulnar nervus at the elbow occurs, information technology is called cubital tunnel syndrome. The cubital tunnel is the second most common location of nervus entrapment in the body (the first most common is in the carpal tunnel, located in the wrist).

Some factors put people at greater gamble for developing ulnar nerve entrapment. These include:

• Arthritis or bone spurs of the elbow
• A prior elbow fracture or dislocation
• Repetitive or prolonged stress caused by activities requiring a bent or flexed elbow

Symptoms of ulnar nerve entrapment include:

• • Pain (or burning sensation) in the elbow, palm or ring/little finger finger
  • Weakness (especially in the pinky finger and in gripping with the mitt) or tenderness in the hand
  • Tingling, numbness, decreased awareness in the palm or band/little finger finger
  • Sensitivity to common cold
  • Tenderness in the elbow joint
  • Hook-like appearance of the hand and wrist

How do you care for ulnar nerve entrapment?

At that place are a variety of nonsurgical treatments that tin can convalesce the pain and potential damage caused by ulnar nervus entrapment. These include:

• Nonsteroidal anti-inflammatories, such as ibuprofen, aspirin and other over-the-counter pain relievers
• Occupational or physical therapy
• A splint or elbow caryatid for cubital tunnel syndrome

For cases in which these methods have not improved the condition, surgery may exist recommended. Boosted factors indicating surgery include:

• Astringent compression of the ulnar nervus
• Muscle weakness
• Damage that has resulted from nerve pinch

Ulnar nervus decompression surgery has been shown to be constructive in a majority of patients. In add-on to providing pain relief, this surgery can prevent farther damage or deterioration, which is necessary to avoid further hand weakness and dumb part. Amidst its benefits are also simplicity and prophylactic.
