A pelvis characterized by an anteroposterior diameter of the inlet greater than the transverse diameter is classified as?
Pelvis are classified as belonging to one of four major groups. The gynecoid pelvis is the classic female pelvis with a posterior sagittal diameter of the inlet only slightly shoer than the anterior sagittal diameter. In the android pelvis, the posterior sagittal diameter at the inlet is much shoer than the anterior sagittal diameter, limiting the use of the posterior space by the fetal head. In the anthropoid pelvis, the anteroposterior (AP) diameter of the inlet is greater than the transverse diameter, resulting in an oval with large sacrosciatic notches and convergent side walls. Ischial spines are likely to be prominent. The platypelloid pelvis is flattened with a sho AP and wide transverse diameter. Wide sacrosciatic notches are common. The pelves of most women do not fall into a pure type and are blends of one or more of the above types. Ref: Cunningham F.G., Leveno K.J., Bloom S.L., Hauth J.C., Rouse D.J., Spong C.Y. (2010).
