Cubital tunnel syndrome is an ulnar neuropathy that can be caused not only by compression at the cubital tunnel level itself, but can also be caused by movement of the elbow. [1] The volume of the cubital tunnel may be reduced when being moved from full extension to a lesser degree of flexion. Symptoms may include a claw hand.
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 ...
Cubital tunnel. Back of right upper extremity, showing surface markings for bones and nerves. The cubital tunnel is a space of the dorsal medial elbow which allows passage of the ulnar nerve around the elbow. Persistent compression of the ulnar nerve in the cubital tunnel is known 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 ...
Osborne's ligament, also Osborne's band, Osborne's fascia, Osborne's arcade, arcuate ligament of Osborne, or the cubital tunnel retinaculum, refers to either the connective tissue which spans the humeral and ulnar heads of the flexor carpi ulnaris (FCU) or another distinct tissue located between the olecranon process of the ulna and the medial epicondyle of the humerus.
Carpal tunnel syndrome (CTS) is a nerve compression syndrome associated with the collected signs and symptoms of compression of the median nerve at the carpal tunnel in the wrist. Carpal tunnel syndrome is an idiopathic syndrome but there are environmental, and medical risk factors associated with the condition. [6][1] CTS can affect both wrists.
The ulnar nerve is a nerve that runs near the ulna, one of the two long bones in the forearm. The ulnar collateral ligament of elbow joint is in relation with the ulnar nerve. The nerve is the largest in the human body unprotected by muscle or bone, so injury is common. [1] This nerve is directly connected to the little finger, and the adjacent ...
[2] [1] If the tunnel narrows or if the contents of the tunnel expand, there will be an increase in pressure. Examples of tunnels are the carpal tunnel, tarsal tunnel, and cubital tunnel. Sometimes compression occurs in areas that are not considered tunnels and where a nerve passes between two mechanically stiffer tissue types that can squeeze ...
