What's the difference between ilium and ischium?

Ilium


Definition:

  • (n.) The dorsal one of the three principal bones comprising either lateral half of the pelvis; the dorsal or upper part of the hip bone. See Innominate bone, under Innominate.

  • (19) It is not appropriate to reconstruct the pelvic ring after resection limited to the anterior part of the pelvis but it is indicated after resections of the whole of the ilium, particularly in children to avoid shortening of the limb with pelvic shift.
  • (20) In older children in whom rigidity of the pubic symphysis did not permit a sufficient amount of acetabular tilt the acetabulum had to be isolated from the rest of the pelvis by a triple osteotomy which consisted of, in addition to the osteotomy of the ilium, osteotomies of the superior pubic ramus and the ischium or the inferior pubic ramus.

Ischium


Definition:

  • (n.) The ventral and posterior of the three principal bones composing either half of the pelvis; seat bone; the huckle bone.

  • (5) The press-fit component without screws demonstrated the greatest motion equaling 162 microns at the ilium, 97 microns at the publis, and 54 microns at the ischium.
