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 ...
The ulnar nerve can suffer injury anywhere between its proximal origin of the brachial plexus all the way to its distal branches in the hand. It is the most commonly injured nerve around the elbow. [ 9 ] [ 10 ] Although it can be damaged under various circumstances, it is commonly injured by local trauma or physical impingement ("pinched nerve").
A nerve decompression is a neurosurgical procedure to relieve chronic, direct pressure on a nerve to treat nerve entrapment, a pain syndrome characterized by severe chronic pain and muscle weakness. In this way a nerve decompression targets the underlying pathophysiology of the syndrome and is considered a first-line surgical treatment option ...
The ulnar nerve is usually moved to prevent pain, as scar tissue can apply pressure to the nerve. [11] The procedure is performed on an outpatient basis allowing discharge the same day, with the arm in a splint to protect the repair for the first week. [10]
Examples of trauma deformities may include but are not limited to: ulnar claw deformity due to ulnar nerve damage from elbow injuries, [12] boutonnière deformity, [1] mallet finger, [13] jersey finger [14] and gamekeeper's thumb, [4] which can result from sport injuries. [4] [15] [16]
