Conjugate, Conjugate Diameter, True Conjugate, Straight Size (True Conjugate)

Conjugate, Conjugate Diameter, True Conjugate, True Conjugate is the distance between the sacral promontory and the most protruding point on the inner surface of the pubic symphysis. Since in a living person the true conjugate cannot be measured accurately, it is calculated by subtracting 1.3-1.9 cm from the diagonal conjugate (diagonal conjugate) - the distance between the sacroiliac joint and the iliopubic eminence of the opposite side of the pelvis (usually it is approximately 12.7 cm).

If the true conjugate is less than 10.2 cm, then vaginal delivery may be difficult or simply impossible; in this case, a caesarean section is often performed as an obstetric aid.



All women need to know the size of the true conjugate. This is one of the key parameters that determines whether you can give birth to a child on your own or whether surgery will be required. When determining labor patency, this parameter is important, because otherwise the chances of an independent birth are reduced. Especially if the first three fetuses were also born through Caesarean section. Is it worth performing the operation prophylactically? The question remains open. You need to first find out your true length.

One important point is that this figure cannot be measured in a living child. The dimensions of a true conjugite should be equal to the distance that we have during diagnosis in case of impossibility of independent birth. In order to carry out



The conjugate is the distance between the promontories of the sacral cavity and the pubic symphysis on each side of the body. This is an important parameter for women who are planning a pregnancy or are expectant mothers. It is determined using ultrasound and can be used to diagnose pelvic problems such as a narrow pelvis, an insufficient or insufficiently dilated cervix, and congenital anomalies.

The conjugate is also known as true conjugate and coordungulate. It measures the distance between what is between the symphysis pubis and the promontory of the sacrum. It is important to note that the true value of the conjugate is difficult to measure in living humans, as it is impossible to accurately measure
