Initial steps…..
FEATURES
1. State of the cervix
2. To note the station of the presenting
part in relation to ischial spines.
3. To test the CPD in the non engaged
head.
4. To note the resilience and elasticity
of the perineal muscles.
Sacrum
It is smooth, well curved
&
usually
inaccessible
beyond the 3 pieces.
Diagonal conjugate
Sacro-sciatic notch
The configuration of the notch
denotes the capacity of the
posterior
segment
of
the
pelvis and the side walls of the
lower pelvis.
Ischial Spines
They may be prominent
&
encroach to the cavity there by
diminishing the available space in
the mid pelvis.
Posterior surface of the symphysis
pubis
It normally forms a smooth
rounded curve. Presence of
angulation or beaking indicates
abnormality.
Pubic angle
A. In narrow angle, it roughly
corresponds
to
fully
abducted middle & index
fingers.
B. The inferior pubic rami are
defined, the angle roughly
corresponds to the fully
abducted thumb and index
fingers.
Transverse diameter of the outlet
It
is
measured
by
placing the knuckles of
the
first
inter
phalangeal joints or
knuckles
of
the
clinched fist between
the ischial tuberosities.
Sidewalls
Normally they are not easily
palpable by sweeping the
fingers unless convergent.
