pelvis is composed

pelvis is composed of four bone: sacrum, coccyx, and two inominata bones that are formed by the fusion of ilium, ischium, and pubis. Inominata jointed bones with the sacrum at sinkondrosis sakroiliaka and jointed with bone inominata next door at the symphysis pubis. The Anatomy of the pelvis is divided into two regions by an imaginary plane drawn from the top to the edge of the sacrum promontorium symphysis pubis, which are: False pelvis, which is located above the field, serves to support the intestinum. True pelvis, which is located below the field, had two openings which are: the superior pelvic arpertura (the top of the pelvis) and inferior pelvic arpetura (the bottom of the pelvis). During the process of the birth of pervaginam, the baby must be able to pass both the true pelvic opening it.

apertura pelvis superiorly Form the top of the pelvis of women, compared with men, tend to be more rounded than oval. There are four doors over the pelvic diameter is used including anteroposterior diameter, transversal diameter, diameter and oblik. Anteroposterior diameter of which is important in obstetrics is the shortest distance between the sacrum promontorium and the symphysis pubis, known as konjugata obtetris. Normally, konjugata obstertis measuring 10 cm or more in diameter, but this can be very short on abnormal pelvic anatomy. Konjugata obsteris anteroposterior diameter with other distinguished known as konjugata vera. Konjugata vera does not describe the shortest distance between the sacrum promontorium and the symphysis pubis. Konjugata obstetris cannot be measured directly with the examination of the finger. For clinical purposes, konjugata obstetris estimated indirectly by measuring the distance of the lower edges of the sacrum promontorium symphysis, i.e. konjugata diagonalis, and the result is reduced 1,5-2 cm.

the smallest pelvic dimensions. The middle of the pelvis is measured as high as spina iskiadika, or field of the smallest pelvic dimensions. Have a special meaning after the engagement the head of the fetus at birth is jammed. Interspinosus diameter, 10 cm in size or slightly larger, usually the smallest pelvic diameters. Anteroposterior diameter of as high as normal-sized iskiadika spina least 11, 5 cm.

apertura pelvis inferior. The bottom of the pelvis is made up of two areas which resemble a triangle. These areas have the same basic line drawn between two tuberosity ischium. Apex of the triangle posteriornya is at the tip of the sacrum and the lateralnya sakroiskiadika ligament and tuberosity is the ischium. The anterior triangle is formed by the area below the pubis arkus. Three door bottom diameter of pelvic Anatomy used the anteroposterior, transversal and sagittal posteriorly. well and Moloy developed a classification of pelvic anatomy which is still used to this day. Caldwell-Molloy classification based on measurements of the diameter of the largest at the top of the transversal flanks and its partition into anterior and posterior segments. These segments form determines the classification of the pelvis to pelvis ginekoid, android, anthropoid, or platipeloid. Posterior segment characters specify the type pelvis, anterior segments and characters determine the tendencies are. Both of these are defined as most of the pelvis is not a pure type, but rather a mix of, for example, ginekoid with pelvic inclination android means Anatomy of the pelvis and pelvic posterior shaped ginekoid shaped anteriornya android.

pelvic ginekoid considered normal female pelvis, while android is a variant of the pelvis of the male pelvis. Pelvic android more often found in women with physical aktivity weight during adolescence. Android is also found in the pelvis of women who experience delays in an upright position, i.e. after the age of 14 months, while the pelvic Anatomy platipeloid more commonly found in women who have the capability of an upright position before the age of 14 months.
