Patient's question:
NoDoctor's answer:
This is to draw a circle between the pubic symphysis in the front (i.e., above) and the vagina below, following the layout of the 12 points on a clock. The 12 o'clock position is below, and the 6 o'clock position is above. The posterior fontanelle is at the 11 o'clock position, indicating a occiput-posterior position, which can easily cause uterine inertia and requires timely correction.
