Abstract

Aim: The morphology of the coccyx varies. This variety makes it difficult to understand the radiologic pathologies in idiopathic coccydynia. This study aimed to examine the coccyx morphology in Turkish society in order to establish a set of societal reference values.

Method: By retrospective analysis of computed tomography scans of one thousand adults, the following were evaluated: number of coccygeal segments, type of coccyxes, sacrococcygeal and intercoccygeal joint fusion, coccygeal spicules, sacrococcygeal straight length, sacrococcygeal and intercoccygeal curvature angles and lateral deviation of the coccyx tip.

Results:The most common number of coccygeal segments was determined to be four, and the most common coccyx type was II. Sacrococcygeal fusion was observed in 69.5%, and intercoccygeal fusion in 83.6%. Coccygeal spicule was seen in 3.7% of the cases. The mean sacrococcygeal straight length was 34.3 mm in males and 32.2 mm in females; this length was also significantly higher in the male group (p<0.001). The mean sacrococcygeal curvature angle was 108.8° in females and 112.7° males; this angle was significantly wider in the male group (p<0.001).

Conclusion: This study, conducted in asymptomatic Turkish individuals, is the most comprehensive study to date and can be used as a “set of societal reference values” in future studies with symptomatic cases to determine the societal morphology of the coccyx and the etiology of coccydynia.

1000 Asemptomatik Türk Erişkinin Multislice 3d Ct'de Ayrıntılı Koksigeal Morfolojisi

Abstract

Amaç: Kuyruk sokumu morfolojisi değişiklik göstermektedir. Bu çeşitlilik idiyopatik koksidinideki radyolojik patolojilerin anlaşılmasını zorlaştırmaktadır. Bu çalışma, bir dizi toplumsal referans değeri oluşturmak için Türk toplumundaki kuyruk sokumu morfolojisini incelemeyi amaçlamıştır.

Yöntem: Bin yetişkinin bilgisayarli tomografi taramasının retrospektif analizi ile aşağıdakiler değerlendirilmiştir: koksigeal segment sayısı, koksiks tipi, sakrokoksigeal ve interkoksigeal eklem füzyonu, koksigeal spiküller, sakrokoksigeal düz uzunluk, sakrokoksigeal ve interkoksigeal eğrilik açıları ve kuyruk sokumu ucunun lateral sapması.

Bulgular: En sık görülen koksiks segment sayısı dört, en sık görülen koksiks tipi ise II olarak belirlenmiştir. Sakrokoksigeal füzyon %69,5, interkoksigeal füzyon ise %83,6 sıklıktadır. Olguların %3,7'sinde koksigeal spikül görülmüştür. Ortalama sakrokoksigeal düz uzunluk erkeklerde 34,3 mm, kadınlarda 32,2 mm idi; bu uzunluk da erkek grupta anlamlı olarak daha yüksekti (p<0,001). Ortalama sakrokoksigeal eğrilik açısı kadınlarda 108,8°, erkeklerde 112,7°; bu açı erkek grupta anlamlı olarak daha genişti (p<0,001).

Sonuç: Asemptomatik Türk bireylerde yapılan bu çalışma bugüne kadar yapılan en kapsamlı çalışma olup, gelecekte semptomatik olgularla yapılacak çalışmalarda kuyruk sokumu kemiğinin toplumsal morfolojisi ve koksidini etiyolojisinin belirlenmesi amacıyla “toplumsal referans değerleri seti” olarak kullanılabilir.
