The sacroiliac (SI) joint is often characterized as a large, auricular-shaped, and diarthrodial synovial joint. The SI ligamentous structure is more extensive in the dorsal part due to the absence of the posterior capsule, which functions as a connecting band between the sacrum and ilium. In addition, a network of muscles supports the SI joint that helps deliver regional muscular forces to the pelvic bones. The third and fourth decades of life promote senescent changes manifested by surface irregularities, crevice formation, fibrillation, and clumping of chondrocytes.
