Morphometric and Computed Tomographic Investigation of Ligamentum Sacrotuberale in Dogs

Öz

The ligamentum sacrotuberale is an anatomical structure that is frequently used in clinical hip dislocations and perineal hernias in dogs. However, various differences have been identified in the description of its anatomical location in the literature. The aim of this study is to contribute to the literature by determining the accuracy of different information specified in the literature and determining its morphology. The study was performed on the cadavers of 7 healthy adult dogs (3 females and 4 males). Three-dimensional reconstruction of the ligamentum sacrotuberale was performed on the images obtained by computed tomography in dogs. Dogs were then dissected and morphometric measurements were made. As a result of the analyses performed, no statistical difference was found when the right and left ligamentum sacrotuberale were compared (P > .05). In our study, it was determined that in all of our dissections performed on dogs, ligamentum sacrotuberale originated from the caudolateral surface of the last sacral vertebra and the craniolateral of the first tail vertebra and ended on the dorsal surface of the tuber ischidicum.

Köpekte Ligamentum Sacrotuberale’nin Morfometerik ve Bilgisayarlı Tomografik İncelenmesi

Öz

Ligamentum sacrotuberale köpeklerde klinik kalça çıkıkları ve perineal fıtıklarda sıklıkla kullanılan anatomik bir yapıdır. Ancak literatürde anatomik yerleşiminin tanımlanmasında çeşitli farklılıklar tespit edilmiştir. Bu çalışmanın amacı, literatürde belirtilen farklı bilgilerin doğruluğunu ve morfolojisini belirleyerek literatüre katkı sağlamaktır. Çalışma 7 yetişkin köpeğin (3 dişi ve 4 erkek) kadavrası üzerinde yapıldı. Köpeklerde bilgisayarlı tomografi ile elde edilen görüntüler üzerinde lig. sacrotuberale’nin üç boyutlu rekonstrüksiyonu yapıldı. Köpekler daha sonra diseke edildi ve morfometrik ölçümler yapıldı. Yapılan analizler sonucunda sağ ve sol ligamentum sacrotuberale karşılaştırıldığında istatistiksel olarak fark bulunmadı (P > .05). Çalışmamızda köpeklerde yaptığımız tüm diseksiyonlarda lig. sacrotuberale’nin son sakral omurun kaudolateral yüzeyinden ve birinci kuyruk omurunun craniolateral yüzeyinden köken aldığı ve tuber ischidicum'un dorsal yüzeyinde sona erdiği belirlendi.
