Abstract

Amaç: Pelvis, insan vücudunun alt kısmında yer alan ve yük taşıma, iç organları koruma, postüral dengeyi sağlama gibi temel görevleri üstlenen kompleks bir anatomik yapıdır. Bunun yanında pelvik yapının doğurganlıkla olan yakın ilişkisi, obstetrik değerlendirmeler başta olmak üzere pek çok klinik alanda morfometrik ölçümlerin önemini artırmaktadır. Yaşla birlikte iskelet sisteminde meydana gelen yapısal ve biyomekanik değişimler, pelvik morfoloji üzerinde anlamlı etkiler yaratabilir. Bu çalışmanın amacı, kadın bireylerde pelvik morfometrik ölçümlerin yaş gruplarına göre değişimini değerlendirmek ve bu değişimlerin klinik yansımalarını ortaya koymaktır.
Yöntem: Retrospektif karşılaştırmalı bu çalışmada, 2010–2025 yılları arasında çekilen bilgisayarlı tomografi (BT) görüntüleri kullanıldı. Çalışmaya 20–40 yaş arası, BT görüntüleri değerlendirilebilir kalitede ve sağlıklı kemik yapısına sahip toplam 74 kadın dahil edildi. Katılımcılar yaşlarına göre iki gruba ayrıldı: 25 yaş ve altı (n=20) ve 25 yaş üzeri (n=54). Conjugata anatomica, conjugata vera, conjugata diagonalis, conjugata recta, diameter transversa, diameter obliqua, intertuberous mesafe ve interspinous mesafe olmak üzere sekiz pelvik parametre ölçüldü. Veriler parametrik ve non-parametrik testlerle analiz edildi; p<0.05 istatistiksel anlamlılık eşiği olarak kabul edildi.
Bulgular: Yaş ortalaması birinci grupta 21,00±2.55, ikinci grupta 39,43±8,6 idi. Gruplar arasında conjugata anatomica, conjugata vera, conjugata diagonalis, conjugata recta, intertuberous mesafe ve interspinous mesafe açısından anlamlı fark saptanmadı (p>0,05). Ancak diameter transversa ve diameter obliqua ölçümleri 25 yaş üzeri grupta istatistiksel olarak anlamlı şekilde daha yüksek bulundu (p <0,05). Ölçümler arası gözlemciler arası uyum yüksek düzeydeydi (ICC: 0,78–0,96).
Sonuç: Kadın pelvis morfometrisi, bazı parametreler açısından yaşla birlikte anlamlı değişiklik göstermektedir. Özellikle diameter transversa ve diameter obliqua ölçümlerinde görülen artış, yaşa bağlı morfolojik değişimlerin pelvis geometrisini etkileyebileceğini düşündürmektedir. Bu bulgular, doğum öncesi planlamalarda ve pelvik cerrahi yaklaşımlarda dikkate alınmalıdır.

COMPARATIVE ANALYSIS OF PELVIC MORPHOMETRY AMONG DIFFERENT AGE GROUPS IN WOMEN

Abstract

Objectives: The pelvis is a complex anatomical structure located in the lower part of the human body, responsible for essential functions such as load-bearing, protection of internal organs, and maintenance of postural balance. Additionally, its close association with fertility underscores the clinical relevance of morphometric assessments, particularly in obstetric evaluations. Structural and biomechanical changes occurring in the skeletal system with advancing age may have significant effects on pelvic morphology. This study aims to evaluate the age-related variation in pelvic morphometric measurements among women and to discuss the potential clinical implications of these changes.

Materials and Methods: In this retrospective comparative study, computed tomography (CT) images acquired between 2010 and 2025 were analyzed. A total of 74 female participants aged between 20 and 40 years, with CT scans of evaluable quality and healthy bony structures, were included. Participants were divided into two age-based groups: ≤25 years (n=20) and >25 years (n=54). Eight pelvic parameters were measured: conjugata anatomica, conjugata vera, conjugata diagonalis, conjugata recta, diameter transversa, diameter obliqua, intertuberous distance, and interspinous distance. Data were analyzed using both parametric and non-parametric statistical tests, with a significance level set at p<0.05.

Results: The mean age was 21.00±2.55 years in Group 1 and 39.43±8.76 years in Group 2. No statistically significant differences were found between the groups for conjugata anatomica, conjugata vera, conjugata diagonalis, conjugata recta, intertuberous distance, or interspinous distance (p>0.05). However, both diameter transversa and diameter obliqua were significantly higher in the >25 years group (p <0.05). Interobserver agreement for all measurements was high (ICC: 0.78–0.96).

Conclusion: Pelvic morphometry in women shows significant age-related differences in certain parameters. The observed increases in diameter transversa and diameter obliqua suggest that age-related morphological changes may alter pelvic geometry. These findings should be considered in prenatal planning and pelvic surgical approaches.
