Excerpt from book: DISSECTION OF THE LOWER LIMB. 1. The Gluteal Region.?The subject being placed on its face, with blocks under the pelvis, an incision is to be made from the middle line outwards, along the crest of the ilium; and another, commencing at the same point, is to be carried down to the lower end of the sacrum, then outwards, so as to reach a point about six inches below the great trochanter. The largest cutaneous nerves of this region cross down over the crest of the ilium and will be found the more easily by attending to the circumstance that while the adipose tissue on the back is continued down in an uninterrupted sheet over the gluteus maximus, a distinct deeper layer of fat fills up the hollow between the crest of the ilium and the upper border of that muscle; and it is between the two layers that the nerves descend. The nerves descending over the crest of the ilium are: Two or th roe branches from posterior divisions of lumbar nerves, and in front of thom the lateral branches of the last dorsal and ilio-hypogastric nerves. Still further forwards, below the anterior superior spine of the ilium, may be found the posterior branch of the external cutaneous nerve of the thigh, which, however, docs not encroach much on the glutcal region; turning upwards round the inferior border of the gluteus maxiiuus muscle, aresome branches of the small sciatic nerve; and piercing the glutens maxiraus, close to its origin, are some small branches from the posterior, divisions of the upper sacral nerves. The adipose tissue is now to be removed, so as to lay bare the strong fascia lata (aponeurosis of the lower limb), covering the anterior part of the gluteus medius muscle, between the crest of the ilium and the upper border of the gluteus maximus; and when that border is reached, extending fr…
