Examples
“That back of mine, he wrote John Morris in June 1953, continues to hurt and the third professor to examine him found that I had a displaced disk in my vertebrae which inflamed the so-called sciatic nerve and the pain was and is unbearable.”
“Thus a better indicator is something called the sciatic notch, which is in the stronger, posterior section of these large bones.”
“The other notches, one on either side, are formed by the sacrum and coccyx behind, the ischium in front, and the ilium above; they are called the sciatic notches; in the natural state they are converted into foramina by the sacrotuberous and sacrospinous ligaments.”

chained_bear I think he means the sciatic nerve. Feb 29, 2008
seanahan Apparently it refers to the hip, or a region near the hip, although this doesn't fit with the citation below. Feb 29, 2008
chained_bear I've never seen this word used as a noun before, as in this (archaic) usage:
"'It is not there that it hurts,' he said in a surprisingly strong voice. 'It is in my goddam leg.'
"'Nonsense, my dear,' said Stephen. 'That is only referred pain from the great sciatic. We are on the very spot itself. It is a pistol-ball lodged between two vertebrae.' He tapped the general region.
"'There? I thought that was the kick of a horse—nothing much at the time.'
"'We are all of us fallible.'"
--Patrick O'Brian, The Letter of Marque, 199 Feb 29, 2008
