Figure 1 Appearance of nerve compression in carpal tunnel syndrome with ultrasonography
Figure 1 | Appearance of nerve compression in carpal tunnel syndrome with ultrasonography. Images are from a 48-year-old female with symptoms of bilateral carpal tunnel syndrome, who had previously had surgery on the right hand with transient partial benefit. Onset of symptoms in the left hand was recent. Ultrasonography of the median nerve in longitudinal view reveals different sites of median nerve compression in each hand. Compression is visible as the notch sign (arrows). Compression is at the distal region of the carpal tunnel, at the capitate bone, in the right hand (top), and in the proximal region of the carpal tunnel at the pisiform level in the left hand (bottom).
