“…1 The three constituents of the coxal bone-the ilium, ischium and pubis ossify at week 9, 18 and 20 gestation, respectively. 12,13 The three bony landmarks-pubic tubercle (PT), IT and iliac crest (seen as dot, comma, bar respectively) which lie at different planes, require some obliquity of views (Figure 7A). PT is un-ossified in our cases which are <20 weeks gestation.…”

Color Doppler (CD) is an established diagnostic modality for bladder exstrophy. We present two mid‐trimester difficult‐to‐diagnose cases with no obvious infraumbilical mass bulge, assessed by CD in sagittal and axial pelvic views. The first case was a classical bladder exstrophy at 19 weeks nestled under the umbilical‐cord and the second case was an omphalocele‐exstrophy‐imperforate‐anus‐spinal complex at 18 weeks 4 days gestation with exstrophic bladder embedded under the omphalocele. The altered course of umbilical arteries in relation to pelvic bony landmarks seen in these fetuses could be an objective approach to complement mid‐trimester diagnosis of bladder exstrophy regardless of mass bulge.

Deepening and generalization of already existing knowledge about rare diseases and congenital anomalies are becoming relevant in modern medicine. Congenital malformations are often combined with other abnormalities, including the genitourinary tract. It is assumed that there is a rare model of associated anomalies limited to a specific area of the body. The purpose of the study was the analysis and generalization of information from the sources of scientific literature on сongenital malformations of the hip bone, their classification and interpretation in alphabetical order. This study is a continuation of our previous research on сongenital malformations of the lower extremities. Results and discussion. Congenital malformations of the pelvic girdle, in particular hip dysplasia and congenital hip dislocation, are the most common. Hip dysplasia occurs with a frequency of 5 to 16%. To understand the morphological background of congenital anomalies of the pelvic bone and their surgical treatment, it is necessary to have an idea of prenatal development not only of each of the three pelvic girdle bones but also the genitourinary system, rectum, and vagina. Among the three parts of the pelvic bone, the process of ossification of the pubic bone is the latest and begins between 5 and 6 months of fetal development. The primary center of ossification is located in the upper part of the future bone in front of the acetabulum and in the immediate vicinity of the sciatic and femoral nerves. Based on the analysis of literature sources, an attempt was made to summarize the existing information on the congenital malformations of the pelvic girdle bones and propose their classification and interpretation according to the alphabet. Conclusion. Pelvic congenital malformations can be both generalized and isolated. Generalized congenital malformations of the pelvic bones lead to a change in the configuration of the whole pelvis, and isolated – involve one bone or part of it. Generalized pelvic congenital malformations include the anatomically narrow pelvis, hypoplastic pelvis, infantile pelvis, uniformly narrowed pelvis, oblique pelvis, funnel-shaped pelvis, flat pelvis, flat narrowed pelvis, transversely narrowed pelvis, scoliotic pelvis, spondylosis. Isolated pelvic bone defects include pubic bone aplasia, hip aplasia, achondrogenesis, achondroplasia, hip hypoplasia, deep acetabulum, hip dysplasia, cleidocranial dysplasia, limbus, neolimbus, retroversion of the acetabulum, and stenosis of the acetabulum

Purposes Skeletodysplasiae and hereditary dysostoses constitute a group of over 350 disorders of the skeletal system. Knowledge about development of the pubic primary ossification center may be useful in both determining the fetal stage and maturity, and for detecting congenital disorders. The present study was performed to quantitatively examine the pubic primary ossification center with respect to its linear, planar, and volumetric parameters. Materials and methods Using methods of computed tomography (CT), digital-image analysis and statistics, the size of the pubic primary ossification center in 33 spontaneously aborted human fetuses (18 males and 15 females) aged 22–30 weeks was studied. Results With no sex and laterality differences, the best-fit growth dynamics for the pubic primary ossification center was modeled by the following functions: y = − 13.694 + 0.728 × age ± 0.356 for its sagittal diameter, y = − 3.350 + 0.218 × age ± 0.159 for its vertical diameter, y = − 61.415 + 2.828 × age ± 1.519 for its projection surface area, and y = − 65.801 + 3.173 × age ± 2.149 for its volume. Conclusions The size of the pubic primary ossification center shows neither sex nor laterality differences. The growth dynamics of the vertical and sagittal diameters, projection surface area, and volume of the pubic ossification centers follow proportionately to fetal age. The obtained numerical findings of the pubic ossification center are considered age-specific reference data with clinical implications in the diagnostics of congenital defects.
