Tridondana Size

Tridondana Size: Measurement of the distance between the upper and lower vertices of the sacral rhombus

In human anatomy, many parameters are used to describe the shape and size of the body. One such parameter is Tridondana Size, which is the distance between the upper and lower apexes of the sacral rhombus. This indicator is important when analyzing the shape of the pelvis and can be associated with various anomalies and conditions.

Tridondana Size is one of the key measurements used to evaluate the anatomical features of the pelvis. It is determined by measuring the distance from the superior apex of the sacrum (the apex of the rhombus) to the inferior apex of the sacrum (the opposite apex of the rhombus). Thus, the tridondana size reflects the vertical height of the sacrum.

The meaning of Tridondan Size may vary depending on the individual characteristics of the person. With a generally uniformly narrowed pelvis, when the pelvis has a narrower shape, Tridondana Size usually increases. This is due to the fact that the upper and lower apexes of the sacrum are closer to each other in a narrow pelvis. On the other hand, in a flat-rachitic pelvis, when the pelvis has a flatter shape, the Tridondana size is usually reduced. In this case, the upper and lower apices of the sacrum are further apart.

Tridondan Size measurement can be useful in assessing the condition of the spine and pelvis, especially when considering deformities, abnormalities, or injuries. For example, an increase in Tridondan Size may indicate the presence of a generally uniformly contracted pelvis, which could potentially affect the processes of labor and require special precautions during childbirth. On the other hand, a decrease in Tridondan Size may be associated with a planar-rachitic pelvis, which may also have clinical significance in assessing the condition of the pelvic organs and determining possible problems with support and mobility of the spine.

However, it should be noted that Tridondana Size is only one of many parameters that are used to assess the shape and size of the pelvis. When analyzing anatomical features, it is always necessary to take a comprehensive approach and evaluate all relevant parameters in order to obtain a more complete understanding of the structure of the pelvic region.

In conclusion, Tridondana Size is an important indicator used in anatomy to measure the distance between the superior and inferior apexes of the sacral rhombus. It can be useful in assessing the shape and condition of the pelvis and in identifying spinal abnormalities and deformities. However, for a more complete analysis, other parameters related to the pelvic region should be taken into account.



Tridondan size (TDR) is the distance between the upper and lower points of the sacral rhombus. TDP is an important indicator when assessing the pelvis in women. This size may be increased or decreased depending on the type of pelvic deformity.

A uniformly narrowed pelvis is characterized by an increase in the TDP, which leads to a wider pelvis and less space for the baby in the uterus. This can lead to problems with labor and increased risks for mother and baby.

A flat-rachitic pelvis, on the contrary, is characterized by a decrease in TDR. This occurs because the pelvis becomes flatter and does not provide enough space for the baby. In this case, there may be problems with the passage of the baby through the birth canal and increased risks for the mother and fetus.

To determine the TDR, special instruments are used, such as a tazometer or a symphysiotome. The doctor measures the distance from the upper to the lower point of the sacral rhombus and compares it with the normal value for a given age and gender. If the TDI is different from normal, this may indicate the presence of pelvic deformities and the need for additional examination.

Thus, TDP is an important measure for assessing the pelvis in women and determining the risk to mother and child during labor. Regular screening and monitoring of TDD can help prevent potential problems and ensure a safe birth.
