The many authors of the past two decades who have discussed the subject of posterior positions of the fetal occiput have consistently adhered to one or the other of two opposite viewpoints regarding the clinical importance of this fairly common obstetric situation. These viewpoints are well expressed in the following pair of representative quotations. Melhado1 writes, "... it (occipitoposterior position) is conceded by all to be the most common obstetric anomaly and is responsible for a higher fetal wastage and greater maternal injury than almost any other condition." In startling contrast, Calkins2 says, "... occiput posterior presentation adds nothing to fetal mortality if treated in the same way we treat occiput anterior presentation. Maternal morbidity is likewise unaffected." It would seem that additional clinical studies are needed.
