Of, pertaining to, or in the region of, the pelvis; as, pelvic cellulitis. [1913 Webster]
Pelvic arch, or Pelvic girdle (Anat.), the two or more bony or cartilaginous pieces of the vertebrate skeleton to which the hind limbs are articulated. When fully ossified, the arch usually consists of three principal bones on each side, the ilium, ischium, and pubis, which are often closely united in the adult, forming the innominate bone. See Innominate bone, under Innominate.
