AMAÇ: Koksiks, vertebral kolonun distalinde yer alan, sakrum alt ucu ile eklem yapan ve sıklıkla 3 veya 4 vertebral segmentten oluşan üçgen şeklinde bir kemiktir. Bu çalışmanın amacı çocukluk çağı yaş grubunda koksiks morfolojisinin ve morfometrisinin manyetik rezonans görüntüleme (MRG) ile değerlendirilmesidir.
GEREÇ VE YÖNTEM: Bu retrospektif çalışmada, Ocak 2020- Ocak 2021 tarihleri arasında hastanemizde lumbosakral veya pelvik MRG ile tetkik edilmiş olan çocuk hastalar çalışmaya dahil edildi. Sakral ve koksigeal vertebraların en iyi şekilde görüntülendiği mid-sagittal, T1 ağırlıklı MRG kesitlerinde vertebraların dizilimleri, listezis varlığı/yokluğu ve koksiks vertebra sayısı kaydedildi. Ayrıca aynı kesitte morfometrik değerlendirmede doğrusal koksiks uzunluğu, sakrokoksigeal açı, sakrokoksigeal eklem açısı ve interkoksigeal açı ölçüldü.BULGULAR: Toplam 47 hasta (36 kız, 11 erkek) çalışmaya dahil edildi. Hastaların yaş ortalaması 13.7±2.1 idi. Kız ve erkek hasta-lar arasında ve farklı yaş grupları arasında (grup 1: 7-10 yaş, grup 2: 11-13 yaş, grup 3: 14-16 yaş); koksiks uzunluğu, sakrokoksi-geal açı, sakrokoksigeal eklem açısı, interkoksigeal açı arasında anlamlı fark saptanmadı (sırasıyla; p= 0,728, p=0,262, p=0,105 ve p=0.191, p= 0.684, p=0.927).
SONUÇ: Bu çalışmaya göre çocukluk çağı yaş grubunda sakrokoksigeal açı, sakrokoksigeal eklem açısı ve interkoksigeal açılar değerlendirildiğinde kız ve erkek hastalar arasında ve farklı yaş grupları arasında farklılık saptanmamıştır. Çocukluk çağı yaş grubunda koksikse ait morfolojik özelliklerin bilinmesi, hastalıkların değerlendirilmesinde kolaylık sağlayacaktır.

EVALUATION OF COCCYX MORPHOLOGY WITH MAGNETIC RESONANCE IMAGING IN CHILDHOOD AGE

Öz

OBJECTIVE: The coccyx is a triangular bone located in distal of the vertebral column, articulating with the lower end of the sacrum, and often consisting of 3 or 4 vertebral segments. The aim of this study is to evaluate coccyx morphology and morphometry in the childhood age group with magnetic resonance imaging (MRI).
MATERIAL AND METHODS: In this retrospective study, children who had lumbosacral or pelvic MRI in our hospital between January 2020 and January 2021 were included. In mid-sagittal, T1-weighted MRI sections, where the sacral and coccygeal vertebrae are best visualized, the alignment of the vertebrae, the presence/absence of listezis, and the number of coccyx vertebrae were recorded. In addition, linear coccyx length, sacrococcygeal angle, sacrococcygeal joint angle and intercoccygeal angle were measured in the same section in the morphometric evaluation.
RESULTS: A total of 47 patients (36 girls, 11 boys) were included in the study. The mean age of the patients was 13.7±2.1. Among female and male patients and between different age groups (group 1: 7-10 years, group 2: 11-13 years, group 3: 14-16 years); There was no significant difference between coccyx length, sacrococcygeal angle, sacrococcygeal joint angle, and intercoccygeal angle (p= 0.728, p=0.262, p=0.105 and p=0.191, p= 0.684, p=0.927, respectively).
CONCLUSIONS: According to this study, when the sacrococcygeal angle, sacrococcygeal joint angle and intercoccygeal angles were evaluated in the childhood age group, no difference was found between male and female patients and between different age groups. Knowing the morphological features of the coccyx in the childhood age group will facilitate the evaluation of diseases.
