Acetabular fossa

Last revised by Yahya Baba on 7 Dec 2020

The acetabular fossa, also known as the cotyloid fossa, is the central aspect of the medial wall of the acetabulum that hosts the ligamentum teres and the fibrofatty pulvinar. It is the nonarticular portion inside the U-shaped labrum that extends to the acetabular notch 1. The acetabular fossa is approximately 6 mm anterior to the true center of the acetabulum 2.
