With the advent of Roentgen methods for surveying the bony pelvis have come many new concepts of the architecture of the female pelvis and its relation to the problems of labor. During the last half dozen years the quest for this newer knowledge has received an extraordinary impetus, obviously due to the excellent results in applying these new truths to practical obstetrics. Methods for measuri...

BACKGROUND Even if lower vaginal delivery success rates and impaired neonatal short-term outcomes have been reported for primiparous women with breech presentation, vaginal breech delivery remains an option for carefully selected patients. Because Magnetic resonance imaging (MRI) pelvimetry can provide additional information on maternal pelvic morphology, we sought to identify new MRI parameter...

BACKGROUND Normal morphological features of the maternal pelvis are an important prerequisite to vaginal delivery. OBJECTIVES We aimed to evaluate the association between obstetric conjugate diameter (OCD) measured by ultrasonography and the type of delivery, vaginally (V) or by cesarean (C) section. PATIENTS AND METHODS Pelvimetry was performed in 200 primigravid women for fetal cephalic p...

Although fetomaternal disproportion is the major cause of dystocia in heifers, pelvis area (PA) is not recommended as a culling tool due to its relatively low importance and genetic correlation with calf birth weight (BWT), the most important factor associated with dystocia. The objective of this observational study of 484 limited bred yearling beef heifers was to compare the effects of differe...
