The Sacroiliac Joint [Part 1] | Major Ligaments & Structures

The video provides an in-depth exploration of the sacroiliac (SI) joint, emphasizing its low mobility and stability. It covers the anatomy of the SI joint, including its cartilage composition and the role of various pelvic ligaments. The video also discusses the anterior and posterior ligaments, their functions, and how they contribute to the joint's stability. A cross-sectional view of the SI joint is presented to illustrate its small surface area and the factors that prevent the sacrum from falling through under weight. The video sets the stage for further exploration of related joints in future videos.

What types of movements are restricted by the sacroiliac joint's structure?

Identify the differences between the sacrotuberous and sacrospinous ligaments.

What is the importance of the interosseous sacroiliac ligaments?

Discuss the factors that contribute to the stability of the sacroiliac joint beyond ligaments.
