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 ...
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 ulnar tunnel syndrome. [4]
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. Along its course it may become compressed at several sites. [2] At the elbow the ulnar nerve passes through the cubital tunnel, where ulnar nerve compression most commonly occurs. [2]

Paresthesia is a sensation of the skin that may feel like numbness (technically called hypoesthesia), tingling, pricking, chilling, or burning. [1] It can be temporary or chronic and has many possible underlying causes. [1] Paresthesia is usually painless and can occur anywhere on the body, but most commonly in the arms and legs. [1]
There are different types of acquired hand deformities, each with distinct characteristics and underlying causes, such as boutonnière deformity, Dupuytren's contracture, gamekeeper's thumb, hand osteoarthritis deformity, mallet finger, swan-neck deformity, ulnar claw hand, among many others.
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).
Carpal tunnel syndrome is sometimes applied as a label to anyone with pain, numbness, swelling, or burning in the radial side of the hands or wrists. When pain is the primary symptom, carpal tunnel syndrome is unlikely to be the source of the symptoms.
