Ulnar nerve impingement along an anatomical space in the wrist called the ulnar canal is known as ulnar tunnel syndrome (or Guyon canal's syndrome). Recognized causes of ulnar nerve impingement at this location include local trauma, fractures, ganglion cysts, [8] and classically avid cyclists who experience repetitive trauma against bicycle ...
Ulnar neuropathy is a disorder involving the ulnar nerve. Ulnar neuropathy may be caused by entrapment of the ulnar nerve with resultant numbness and tingling. [3] It may also cause weakness or paralysis of the muscles supplied by the nerve. Ulnar neuropathy may affect the elbow as cubital tunnel syndrome. At the wrist a similar neuropathy is ...
Orthopedic surgery. Ulnar tunnel syndrome, also known as Guyon's canal syndrome or Handlebar palsy, is ulnar neuropathy at the wrist where it passes through the ulnar tunnel (Guyon's canal). [1] The most common presentation is a palsy of the deep motor branch of the ulnar nerve causing weakness of the interosseous muscles.
Cubital tunnel syndrome is an entrapment neuropathy, or nerve compression syndrome, a condition caused by compression, traction or friction, of the ulnar nerve at the elbow. [1] Nerve compression is also known as a trapped nerve. The ulnar nerve travels from the shoulder (brachial plexus) down the length of the arm to the hand.
Pronator teres syndrome. Pronator teres syndrome is a compression neuropathy of the median nerve at the elbow. It is rare compared to compression at the wrist ( carpal tunnel syndrome) or isolated injury of the anterior interosseous branch of the median nerve ( anterior interosseous syndrome ).
Differential diagnosis. Ulnar nerve neuropathy, Cervical myelopathy. Wartenberg's sign is a neurological sign consisting of involuntary abduction of the fifth (little) finger, caused by unopposed action of the extensor digiti minimi. [1] [2]
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve, though this may also refer to nerve root compression (by a herniated disc, for example). Its symptoms include pain, tingling ...
The "radial tunnel" is the region from the humeroradial joint past the proximal origin of the supinator muscle. Some scientists believe the radial tunnel extends as far as the distal border of the supinator. The radial nerve is commonly compressed within a 5 cm region near the elbow, but it can be compressed anywhere along the forearm if the ...
