Pelvis Oblique

A constricted pelvis is one of the most common forms of congenital disorder of the pelvic ring, which plays an important role in the birth of a child. It occurs as a result of compression of the anatomical cone of the pelvis and the formation of an angle between the iliac and sacral bones. In this case, the pelvic bones can be compressed on one side and stretched on the other. Such an anomaly is fraught with complications during childbirth and is one of the risk factors for the appearance of disproportions and deviations in the position of the child at birth.

Experts identify several main signs indicating the presence of a constricted pelvis:

The presence of a wide straight line of the lumbosacral joint. The intersection points of the pubic and sacral arches, located under the sacral apex (baby's head). The distance between the anterior end of the pelvic plane to the upper ischial pubic points.

The pelvis is oblique

An obliquely contracted pelvis (synonymously obliquely displaced, narrowly asymmetrical, asymmetrical, etc.) is one of the reasons for suboptimal load distribution during normal childbirth and, as a consequence, water births, epidural anesthesia, cesarean section and negative postpartum consequences for the mother and fetus. In fact, oblique pelvises are biological prerequisites for traumatic childbirth. In the presence of a constricted pelvis or pelvic dysplosis, there are risks of ruptures of the birth canal of any severity, cervical ruptures, severe and prolonged bleeding, fetal hypoxia, and even fetal vacuum aspiration syndrome (VAS). At the moment, there are no uniform reliable criteria for diagnosing a constricted pelvis. It can only be identified through a clinical examination aimed at identifying the following diagnostic signs: asymmetry of the sacral cavities, hyperduction of the external right angle, asymmetry of sacral flexion, plantation of the ischial spine, severe obstruction of the saphenous veins and chrysological deformation of the ischium. All of the above are signs of an obliquely constricted (obliquely displaced), or rather obliquely positioned pelvis, so any midwife should have them when examining patients. However, it is necessary to take into account the complexity of auscultation during pregnancy, which has its own characteristics. The basis of this method is audiometry in obstetrics - assessing the condition of the fetus by auscultatory percussion or listening to indirect fetal heart sounds during a special external obstetric examination of the fetus - fetal auscultophoresis by tapping through the anterior abdominal wall of the mother. That is, the method serves primarily to assess the adequacy of the blood supply to the fetus during childbirth. However, obstetricians-gynecologists, especially outside regions with low technical equipment, due to the lack of modern equipment, may simply not identify possible problems during childbirth in a pregnant woman.
