Abstract

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.

Abstract

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.
