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.
Radial neuropathy is a type of mononeuropathy which results from acute trauma to the radial nerve that extends the length of the arm. [3] It is known as transient paresthesia when sensation is temporarily abnormal.
Damage to the radial nerve from a shaft fracture can be identified by an inability to bend the hand backwards or by decreased sensation in the back of the hand. [5] Images of the distal region are often of poor quality due to the patient being unable to extend the elbow because of pain.
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 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 ...
Wartenberg's sign is not a feature of, and should not be confused with, Wartenberg's syndrome. The latter involves compression at the wrist of the superficial sensory branch of the radial nerve which does not innervate hand muscles. [citation needed]
The radial nerve is a nerve in the human body that supplies the posterior portion of the upper limb.It innervates the medial and lateral heads of the triceps brachii muscle of the arm, as well as all 12 muscles in the posterior osteofascial compartment of the forearm and the associated joints and overlying skin.
Signs and Symptoms Radiculopathy is a diagnosis commonly made by physicians in primary care specialties, orthopedics , physiatry , and neurology . The diagnosis may be suggested by symptoms of pain, numbness , paresthesia , and weakness in a pattern consistent with the distribution of a particular nerve root , such as sciatica .
