Ulnar Nerve Entrapment (Cubital Tunnel Syndrome)
Ulnar nerve entrapment occurs when the ulnar nerve in the arm becomes compressed.
The ulnar nerve is one of the main nerves in your arm. It travels from your neck down into your hand and can be constricted in several places along the way, such as beneath the collarbone, the elbow or at the wrist. The most common place for compression of the nerve is behind the inside part of the elbow (behind the “funny bone”). Ulnar nerve compression at the elbow is called cubital tunnel syndrome.
Numbness and tingling in the hand and fingers are common symptoms of cubital tunnel syndrome. In most cases, symptoms can be managed with nonsurgical treatments like changes in activities and bracing. If nonsurgical methods do not improve your symptoms, or if the nerve compression is causing muscle weakness or damage in your hand, surgical management may be required.
