Cephalo-pelvic disproportion 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.
