Flexion pelvic wall or pelvic floor. it normally flexes so the chin
makes contact with the fetal chest
The maternal pelvic inlet is widest in the transverse di-
ameter, therefore the fetal head passes the inlet into the
true pelvis in the occipitotransverse position. for the fetus
to exit the head must rotate. internal rotation begins at
the level of the ischial spines but is not complete until the

After head is born it rotates briefly to the position it oc-
cupied when it was engaged in the inlet. this movement
is referred to as restitution. The 45-degree turn realigns
the infants head with his or her back and shoulders. the
head can then be seen to rotate further. this external
restitution and external rotation rotation occurs as the shoulders engage and descend in
maneuvers similar to those of the head. anterior shoulder
descends first when it reaches the outlet, it rotates to the
midline and is delivered from under the pubic arch. the
posterior shoulder is guided over the perineum until it is
free.
After birth of the shoulders, the head and shoulders are
