The median nerve is one of the main nerves in the hand. It originates as a group of nerve roots in the neck; these roots then come together to form a single nerve in the arm. The median nerve travels down the upper arm, across the elbow, and into the forearm, then passes through the carpal tunnel at the wrist on its way to the hand and fingers.Tinel’s test; Phalen’s test; Diagnostic Performance Characteristics. To diagnose carpal tunnel syndrome with high sensitivity and specificity, a positive median nerve compression test needs to be accompanied by a patient completed hand-diagram, the presence of night pain and abnormal sensibility by monofilament testing.
Pronator Syndrome is a compressive neuropathy of the median nerve at the level of the elbow. Diagnosis is made clinically with pain at the proximal volar forearm, sensory changes over the palmar cutaneous branch, and positive Tinel's over the proximal volar forearm.
Introduction [edit | edit source]. Pronator Teres Syndrome (PTS) is a compression neuropathy of the median nerve at the elbow. It is not as common as compression at the wrist which is Carpal Tunnel Syndrome (CTS). PTS and CTS present similarly, however PTS can be distinguished by a lack of sensation in the distribution of the palmar cutaneous branch of the median nerve .the Tinel sign. 10. To perform the hand eleva-tion test, the patient raises his or her hands . Median nerve compression test 64 83 Apply direct pressure over the transverse carpal ligament . Tinel’s sign (lightly tapping over the nerve to see if it generates a tingling sensation) Phalen’s test (pushing the dorsal surface of hands together and holding 30 – 60 seconds) Carpal Compression Test (Apply pressure with thumbs over the median nerve within the carpal tunnel, located just distal to the wrist crease. The test is positive .
Nerve compression syndromes of the hand present with various signs and symptoms that correspond to the nerve involved and its anatomic distribution. There are three nerves and their corresponding branches that provide sensory and motor innervation to the hand that include the median, ulnar, and radial. An understanding of the anatomy and distribution of .Tinel's test — positive if tapping lightly over the median nerve at the volar surface of the wrist produces paraesthesia or pain in the median nerve distribution. Durkan's test (carpal tunnel compression test) — positive if direct pressure over the proximal edge of the transverse carpal ligament (proximal wrist crease) with the thumbs .

DISCUSSION. Carpal tunnel syndrome is the most commonly treated compression neuropathy and continues to be controversial in both diagnosis and treatment (17–19).The prevalence of carpal tunnel syndrome has been reported to be as high as 2.7% in the general population ().While CTS is a clinical diagnosis, many clinical tests have been described for its detection. Tinel’s test. Tinel’s test is used to identify median nerve compression and can be useful in the diagnosis of carpal tunnel syndrome. To perform the test, simply tap over the carpal tunnel with your finger. Interpretation. If the patient develops tingling in the thumb and .
Cubital Tunnel Syndrome is a compressive neuropathy of the ulnar nerve at the elbow, and is the 2nd most common compression neuropathy of the upper extremity. It typically presents with paresthesias of the small and . The median nerve is usually damaged at either the elbow, due to a fracture of the humerus bone of the upper arm, or the wrist, due to either carpal tunnel syndrome or a wrist laceration or gashing. If the .
The Hoffman-Tinel sign, now more commonly known as the Tinel sign, was defined in 1915 by Paul Hoffmann and Jules Tinel as the "pins and needle feeling" elicited by tapping on a nerve proximally, with resulting paresthesia experienced in the corresponding distal cutaneous distribution of an injured peripheral nerve. Hoffmann and Tinel both individually .The Median Nerve begins in the axillary region with the root of median nerves situated in the anterior rami of C5-T1. Median and lateral cords of the brachial plexus are merged and extended as the median nerve. Uniting either in front of or lateral to that vessel. Its fibers are derived from the sixth, seventh, and eighth cervical and first thoracic nerves.
Even though these tests have a wide range of sensitivity ranging from 57-94% and specificity ranging from 51-97%, still nerve conduction studies (NCSs) are utilized as the gold standard to prove . Study Design Resident's case problem. Background Entrapment neuropathies represent a diagnostic challenge and require a comprehensive understanding of the nerve's path and the anatomical structures that may cause compression of the nerve. This resident's case problem details the evaluation and differential diagnosis process for median nerve entrapment . Carpal tunnel syndrome (CTS) accounts for approximately 90% of all focal entrapment neuropathy, making it a frequent electrodiagnostic consultation. It is present in about 3.8% of the general population. It is more common in women than in men, and while it occurs in all age groups, incidence generally reaches a peak within the age of 40 to 60 years.[1] .The diagnosis of carpal tunnel syndrome is strongly suggested by the Tinel sign, in which median nerve paresthesias are reproduced by tapping at the volar surface of the wrist over the site of the median nerve in the carpal tunnel. . is also suggestive. The median nerve compression test is positive if symptoms develop within 30 seconds. The 6 .

Carpal tunnel syndrome just happens to be one of the most common median nerve entrapments. It occurs when the nerve is compressed in the wrist. Less often, compression of the median nerve occurs in the forearm. The result can be one of two other median nerve entrapments: pronator syndrome and anterior interosseous nerve syndrome. These .
Notes. Variations exist between studies on the location and number of taps necessary to elicit a positive response, and in some studies the test is performed by tapping the median nerve in 20 degrees of wrist extension, while others tap along the path of the median nerve up to where the median nerve enters the carpal tunnel.. The Tinel sign is elicitable . The sign indicates the compression or regeneration of peripheral nerve fibers. In modern parlance, the Tinel sign is a provocative test used in suspected cases of entrapment neuropathies affecting either the median nerve within the carpal tunnel or the ulnar nerve in the postcondylar groove.
