Among causes of low back pain, sacroiliac joint pain has historically been neglected in terms of understanding, diagnosis, and available treatment options. Sacroiliac joint dysfunction is a significant source of disability and functional impairment in elderly, and research suggests that the impact on quality of life may be comparable to other surgically treated conditions, including lumbar spinal disease and hip osteoarthritis (1,2). Furthermore, several studies have determined that lumbar/lumbosacral fusion is associated with the development of sacroiliac joint dysfunction (3-5). Recent scientific and technical advances have increased our collective understanding of sacroiliac joint dysfunction and inspired new efforts to define optimal treatment approaches (6,7).
