- Discussion:
-
sciatic nerve is palpated by rolling it under surgeon's finger as it crosses
ischial projection from posteroinferior aspect of the acetabulum;
- palpate sciatic nerve as it passes superficial to obturator internus & gemelli;
-
sciatic nerve emerges below
piriformis & passes downwards
superficial to
obturator internus & gemelli & quadratus femoris;
- if possible, sciatic nerve should be reidentified every time hip is moved;
- it is not always necessary to identify
sciatic nerve, unless hip joint is
grossly distorted;
- in fact, dissection to see nerve may cause unnecessary bleeding
from the vessels lying in the fat around it;
-
sciatic nerve sometimes divides into a tibial and peroneal brach within
pelvis, and on occassion one may identify the
sciatic nerve but think that
it looks to small, then search for the other branch;
