In case of carpal tunnel syndrome, there is a narrowing under the transverse ulnar ligament in the wrist canal (carpal tunnel). In addition to flexor tendons of muscles of the hand and fingers, there is also a nerve that innervates the hand: the median nerve. A thorough clinical and also device-assisted examinations (electrophysiological examination/MRI if indicated) can help diagnose a bottleneck that affects the median nerve.
Carpal tunnel syndrome emerges in middle and higher age, and more frequently women are affected. But the carpal tunnel syndrome is also to develop earlier, for example, during pregnancy.
