Abstract

Ultrasonography in cases of carpal tunnel syndrome is described with respect to the following aspects: (1) imaging technique; (2) image characteristics; (3) detection of pathophysiology; (4) diagnosis of idiopathic cases; (5) screening of local pathologies (space-occupying lesions, tenosynovitis, and bone and joint abnormalities), incomplete release, and anatomic variations; and (6) role in facilitating minimally-invasive surgery.
