The SI Joint and Back Pain
New insight and treatments are bringing relief to patients hobbled by sacroiliac joint dysfunction.
Degeneration of the lumbar vertebrae and the disks that cushion them is a well-established cause of low-back pain. But, a more nebulous source of low-back pain is the sacroiliac (SI) joint, formed by the triangular sacrum at the base of the spine and the iliac crest of the pelvis. For years, experts suspected the SI joint as a common culprit underlying low-back pain, but they just weren’t sure how best to treat it. That situation has changed.
