Sonoanatomy of the Sciatic Nerve

Ultrasound is a dynamic process whereby structures can and should be followed to their origins and destinations for optimal identification. Because of this, it is not always satisfactory to study static ultrasound images. When studying sonoanatomy, the authors strongly advise readers to first study the macro- and microanatomy and then to view the accompanying video productions that illustrates the dynamic sonoanatomy (Movies 1-3). In this chapter, the authors explain the static sonoanatomy of the sciatic nerve at the parasacral, the subgluteal, mid-femoral and the popliteal areas, and with the aid of a video production, the dynamic sonoanatomy of these structures and areas.
