3. ● The pelvic is a ring shaped structure.
● It connected to front by the pubic
symphysis and behind by the sacro_iliac
joints.
● The pelvic ring is formed in continuity of
from the front by puvic symphysis, pubic
crest, pectineal line of pubis, arcuate line
of the ilium and ala and promontory of the
sacrum.
4. The obturator nerve and the sacral plexus
pass over the ala of the sacrum and cross
the pelvic brim.
