Cephalopelvic disproportion

SpecialtyObstetrics

Cephalopelvic disproportion (CPD) exists when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal. This may be due to a small pelvis, a nongynecoid pelvic formation, a large fetus, an unfavorable orientation of the fetus, or a combination of these factors. Certain medical conditions may distort pelvic bones, such as rickets or a pelvic fracture, and lead to CPD.

Transverse diagonal measurement has been proposed as a predictive method.[1]
