| anthropoid pelvis |
Pelvis in which the brim is oval in shape, with an increase in the anteroposterior diameter and a corresponding decrease in the transverse diameter; the sacrum is long and narrow and may contain six vertebrae from fusion of the fifth lumbar vertebra wit the sacrum. This increases the inclination of the pelvic brim and is called high assimilation; it tends to hinder engagement of the fetal head. Noted in tall, well-built women. Labor is usually easy. AKA pithecoid pelvis.
