Shear wave elastography in the diagnosis of the ulnar tunnel syndrome.

An interesting alternative to traditional diagnostic techniques of the upper extremity nerve entrapments might be provided by an ultrasound elastography that started to gain attention in recent research. The aim of this preliminary study was to verify if quantitative analysis of ulnar nerve stiffness with shear-wave elastography can be used to diagnose the ulnar tunnel syndrome, an ulnar nerve neuropathy at the Guyon's canal. The study included 46 patients (39 women) and 39 healthy controls (34 women).
