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 chief complaint of this disease is usually pain in the dorsal aspect of the upper forearm, and any weakness described is secondary to the pain. Tenderness to palpation occurs over the area of the radial neck. Also, the disease can be diagnosed by a positive "middle finger test", where resisted middle finger extension produces pain.
Symptoms vary depending on the severity and location of the trauma; however, common symptoms include wrist drop (the inability to extend the wrist upward when the hand is palm down); numbness of the back of the hand and wrist, specifically over the first web space which is innervated by the radial nerve; and inability to voluntarily straighten ...
Symptoms of radial neuropathy vary depending on the severity of the trauma; however, common symptoms may include wrist drop, numbness on the back of the hand and wrist, and inability to voluntarily straighten the fingers. Loss of wrist extension is due to loss of the ability to move of the posterior compartment of forearm muscles.
Osteoarthritis commonly affects three main sites in the hand: the base of the thumb, where the thumb and wrist converge, known as the carpometacarpal (CMC) joint; the joint closest to the fingertip, referring to the distal interphalangeal joint (DIP); the middle joint of a finger, referring to the proximal interphalangeal joint (PIP).

Sensory deficit: Numbness and tingling in radial half of dorsum of hand, and dorsal aspect of radial 3 + 1 ⁄ 2 digits, excluding their nail beds. In Wartenberg's syndrome, there is significant radial wrist pain, and close resemblance to symptoms in de Quervain's tenosynovitis. Finkelstein's test may be positive. [11]
An illustration of wrist pain. Wrist pain or open wrist is a syndrome inhibiting use of a hand due to pain in anatomical structures of the wrist. [1] It most commonly results from an injury to a ligament. [1] The pain may be sharp from a traumatic injury or from chronic repetitive wrist activities. [1]
Its symptoms include pain, tingling, numbness and muscle weakness. The symptoms affect just one particular part of the body, depending on which nerve is affected. The diagnosis is largely clinical and can be confirmed with diagnostic nerve blocks. Occasionally imaging and electrophysiology studies aid in the diagnosis. Timely diagnosis is ...
