Excerpt from Encyclopaedia Medica, Vol. 11: Sciatica to Syncope AN indefinite term applied to conditions associated with pain in the region of the sciatic nerve. This important nerve trunk is the continuation downwards of the main part of the sacral plexus (see spinal cord, p. It arises in the pelvis, and enters the buttock through the great sacro-sciatic foramen below the pyriformis muscle, and extends down to about the middle of the thigh, where it terminates by dividing into the external and internal popliteal nerves. In position the main trunk of the sciatic nerve lies rather internal to the mid-point between the ischial tuberosity and the great tro chanter of the femur. It supplies muscular branches to the ham-string muscles on the back of the thigh and the main part of the adductor magnus. A knowledge of the course and distribution of its main branches is essential for understanding the diseases of the nerve trunk.
