Radial neuropathy; Other names: Radial mononeuropathy, Saturday night palsy: The suprascapular, axillary, and radial nerves. Specialty: Neurology Symptoms: Wrist drop [1] Causes: Broken bone, Direct nerve injury [2] Diagnostic method: MRI, Ultrasound [3] Treatment: Corticosteroid, Pain medication [2]
Radial nerve dysfunction is a problem associated with the radial nerve resulting from injury consisting of acute trauma to the radial nerve.The damage has sensory consequences, as it interferes with the radial nerve's innervation of the skin of the posterior forearm, lateral three digits, and the dorsal surface of the lateral side of the palm.
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).
The radial nerve is commonly compressed within a 5 cm region near the elbow, but it can be compressed anywhere along the forearm if the syndrome is caused by injury (e.g. a fracture that puts pressure on the radial nerve). [3] The radial nerve provides sensation to the skin of posterior arm, posterior and lateral forearm and wrist, and the ...
On nerve conduction studies, the pattern of diminished compound muscle action potential and normal sensory nerve action potential may be seen given that the lesion is proximal to the posterior root ganglion. Needle EMG is the more sensitive portion of the test, and may reveal active denervation in the distribution of the involved nerve root ...
The latter involves compression at the wrist of the superficial sensory branch of the radial nerve which does not innervate hand muscles. [citation needed] Robert Wartenberg (1887-1956) was a neurologist born in Belarus who worked in Germany until 1935 when he emigrated to the United States. He was widely published and described a number of ...
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.
The disorder is sometimes called chronic relapsing polyneuropathy (CRP) or chronic inflammatory demyelinating polyradiculoneuropathy (because it involves the nerve roots). [2] CIDP is closely related to Guillain–Barré syndrome and it is considered the chronic counterpart of that acute disease. [ 3 ]
