Abstract
Material and methods. The study was conducted using 51 specimen of normal female pelvis with ligaments from the Fundamental Museum of Department of Normal Anatomy of Military Medical Academy. To characterize the shape of pelvis the following standard pelviometric indexes had been used: pelvic ring index (PRI), pelvic height-width index (PHWI), pelvic width index (PWI), pelvic outlet expansion index (PEI).

Material and methods. The study was conducted using 51 specimen of normal female pelvis with ligaments from the Fundamental Museum of Department of Normal Anatomy of Military Medical Academy. To characterize the shape of pelvis the following standard pelviometric indexes had been used: pelvic ring index (PRI), pelvic height-width index (PHWI), pelvic width index (PWI), pelvic outlet expansion index (PEI).
Results. It was established, that none of the above indexes could adequately characterize the shape of pelvic outlet. Therefore, a new parameter was proposed for its evaluation: a sagittal-transverse pelvic index (STPI), a percentage ratio of distantia symphyzo-sacralis to transverse diameter of the outlet of pelvis. In our opinion, from the analyzed indexes, PRI, PHWI and STPI should be used for complex evaluation of the shape of small pelvis. These indexes characterize it most completely, and it’s this part of pelvis, which is most important during operative procedures on pelvic organs or execution of diagnostic manipulations. Morphometric analysis of the group of female pelvises from the collection of the Fundamental Museum of Department of Normal Anatomy of Military Medical Academy has shown that according to the indexes used, the most widely spread shapes of pelvises are: mesopelvic (61%) according to PRI, medium (76%) according to PHWI, harmonic (65%) according to PWI, uniform (76,4%) according to PEI and round (72,5%) according to STPI. Marginal pelvic shapes in terms of PRI, PHIWI, PWI, PEI and STPI occur in 9,8% - 20% of population.
Conclusions. It can be assumed, that the modem imaging methods, such as MRI and CT, would allow us to measure the dimensions of pelvis, necessary for calculation of these indexes in a living person.
