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 .
Symptoms are pain and tenderness at the radial side of the wrist, fullness or thickening over the thumb side of the wrist, painful radial abduction of the thumb, and difficulty gripping with the affected side of the hand. [2] Pain is made worse by movement of the thumb and wrist, and may radiate to the thumb or the forearm. [2]
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.
Ulnar neuropathy at the cubital tunnel is diagnosed based on characteristic symptoms and signs. Intermittent or static numbness in the small finger and ulnar half of the ring finger, weakness or atrophy of the first dorsal interosseous, positive Tinel sign over the ulnar nerve proximal to the cubital tunnel, and positive elbow flexion test (elicitation of paresthesia in the small and ring ...
Wrist structures prone to injury are the triangular fibrocartilage complex and the scapholunate ligament. [1] Wrist sprains may occur when a ligament is ruptured or lacerated in severe trauma, stretched or twisted. [1] Commonly, wrist pain is caused by sudden load-bearing or twisting effects, such as falling from a height with an outstretched ...
Cheiralgia paraesthetica (Wartenberg's syndrome) is a neuropathy of the hand generally caused by compression or trauma to the superficial branch of the radial nerve. [1] [2] The area affected is typically on the back or side of the hand at the base of the thumb, near the anatomical snuffbox, but may extend up the back of the thumb and index finger and across the back of the hand.
Symptoms: Elbow pain, pain with elbow movement, or pain at the elbow with wrist movement. Burning sensation in the forearm. Diminished grip strength. Treatment: Rest, ice, physical therapy, steroids, and NSAIDs. Prognosis: Usually well managed with conservative treatment within 6-12 months depending on duration and severity of symptoms.
Some symptoms of an extensor carpi ulnaris injury include pain when shaking hands or when squeezing/gripping an object. The pain worsens when a person moves their wrist with force. This pain intensifies because the extensor carpi ulnaris has an injury near the elbow area and as a person moves their arm, the muscle contracts, thus causing it to ...
