  it's the bony portion. remember there an outlet and an inlet for the true pelvis. If there is a smaller diameter in the place between these, i guess that would be a mid-pelvic contraction.

if you're forcing the uterus even more (with oxytocin augmentation) to push the baby out against an orifice that's too small to let it pass thru, it will rupture!

  Maternal causes of feto-pelvic disproportion

A. Inlet contraction (diameters): Obstetric conjugate (unengaged head in nulliparous pt)
B. Mid-pelvic contraction (diameters): diameter of mid-pelvis (ischial spines), arrest at 2 or 3+ station
C. Outlet contraction (diameters): diameter of ischial tuberosity (rare alone)
D. Soft tissue obstruction: inflammed and swollen tissue, fibroids, vaginal mass, ovarian cyst, pelvic kidney, sacro-coccygeal teratoma, cervical stenosis, impacted feces, enlarged bladder

The distance between the ischial spines is 10,5 cm, when the fetal head reaches these spine, it is at position zero, if these spines are prominent, the head can not go through and C-section is indicated.

Giving oxytocin is like pushing a car through a dead end, so you will rupture the uterus.
