MORPHOMETRY OF THE ABDOMINAL WALL AND PELVIS IN PUBERTAL GIRLS

Abstract

The study investigated morphometric characteristics of the anterior abdominal wall and spatial pelvic parameters in pubertal girls considering the phases of sexual maturation. A total of 112 girls aged 10–17 years were examined. Morphometric measurements were carried out according to ISAK international standards using traditional anthropometry and elements of geometric morphometry. Somatometric indicators (height, body weight, BMI, waist circumference, and circumference length at the level of the anterior superior iliac spines) and spatial parameters of the anterior abdominal wall (linear distances and angles between key anatomical landmarks) were assessed. Statistical analysis was performed using Student’s t-test. The results demonstrated a significant increase in the main somatometric and morphometric indices in the older pubertal group (14–17 years) compared with the younger group (10–13 years), indicating pelvic lateralization and the formation of the female morphotype. The increase of the ∠SR–XP–SL and ∠SR–P–SL angles confirmed the widening of the pelvic inlet and the expansion of the subpubic angle as anatomically important features associated with future reproductive function. The findings are of practical importance for pediatric surgery and gynecology, as they can optimize the planning of minimally invasive interventions in pubertal girls. Perspectives for further research include expanding the study sample considering regional and ethnic characteristics, applying advanced 3D visualization methods, and developing age-specific morphometric standards, which will improve diagnostic accuracy and enhance the safety of clinical interventions.
