Pelvimetry
Aka: Pelvimetry, Caldwell-Moloy Pelvis Classification, Diagonal conjugate, Intertuberous Diameter
- Caldwell-Moloy Classification
- Gynecoid Pelvis (50%)
- Pelvic brim is a transverse ellipse (nearly a circle)
- Most favorable for delivery
- Android Pelvis (Male type)
- Pelvic brim is triangular
- Convergent Side Walls (widest posteriorly)
- Prominent ischial spines
- Narrow subpubic arch
- More common in white women
- Anthropoid Pelvis
- Pelvic brim is an anteroposterior ellipse
- Gynecoid Pelvis turned 90 degrees
- Narrow ischial spines
- Much more common in black women
- Platypelloid Pelvis (3%)
- Pelvic brim is transverse Kidney shape
- Flattened gynecoid shape
- Determination of an Adequate Pelvis
- Diagonal conjugate
- Distance from sacral promontory to symphysis pubis
- Approximate length of fingers introitus to Sacrum
- Adequate Diagonal conjugate > 11.5cm

- Intertuberous Diameter
- Distance between Ischial tuberosities
- Approximately width of fist
- Adequate Intertuberous Diameter > 10 cm
- Images

- Prominence of ischial spines
