Symptoms are pain and tenderness at the radial side of the wrist, fullness or thickening over the thumb side of the wrist, painful radial abduction of the thumb, and difficulty gripping with the affected side of the hand. [2] Pain is made worse by movement of the thumb and wrist, and may radiate to the thumb or the forearm. [2]
Finkelstein's test was described by Harry Finkelstein (1865–1939), an American surgeon, in 1930. [5]A similar test was previously described by Eichhoff, in which the thumb is placed in the palm of the hand and held with the fingers, and the hand is then ulnar deviated (see images), causing intense pain over the radial styloid which disappears if the thumb is released.
The theory is that the radial nerve becomes irritated and/or inflamed from friction caused by compression by muscles in the forearm. [1]Some speculate that radial tunnel syndrome is a type of repetitive strain injury (RSI), but there is no detectable pathophysiology and even the existence of this disorder is questioned.
In cases of minor wrist pain, CTS, arthritis, injuries and sprains, it's often recommended that the patient wear a wrist brace throughout the healing process to provide extra support, pain relief ...
Some computer keyboards come with a wrist rest included. [5] Beyond the typical wrist rest designs, some companies have created variations that add extra functionality or aesthetics. For example, a laptop with a foldable wrist rest, [6] a game pad with a stylized Pokémon wrist rest, [7] or a wrist rest that also functions as a mouse. [8]
Various imaging techniques can also be used to show nerve compression such as x-ray for the wrist, and MRI for the thoracic outlet and cervico-brachial areas. Utilization of routine imaging is useful in early detection and treatment of overuse injuries in at risk populations, which is important in preventing long term adverse effects.
Anterior interosseous syndrome is a medical condition in which damage to the anterior interosseous nerve (AIN), a distal motor and sensory branch of the median nerve, classically with severe weakness of the pincer movement of the thumb and index finger, and can cause transient pain in the wrist (the terminal, sensory branch of the AIN innervates the bones of the carpal tunnel).
CTS, although prevalent, seems to be very difficult to ameliorate or cure due to the consistency in the design of computer components such as the mouse and the keyboard, but some companies are leading the way with technologies such as touch screen monitors which will reduce stress on the hand and wrist.
