The sacroiliac joint (SIJ) is a common source of low back pain. SIJ pain has shown to have negative impact on patients' quality of life.

One hypothesis is that the SIJ ligaments are structurally altered in SIJ pain. ⋯ Collagen, electron microscopy, histological and ultrastructural assessment, interosseous sacroiliac ligament, low back pain, sacroiliac joint.
