Degenerative arthritis, or osteoarthritis of the spine, can cause degeneration within the sacroiliac joints and lead to inflammation and joint pain. Any form of spondyloarthropathies, which includes ankylosing spondylitis, psoriatic arthritis , reactive arthritis or arthritis related to inflammatory bowel diseases , including ulcerative colitis ...
The earliest and most common symptom is back pain, which worsens with activity. [5] [6] Muscles relax when asleep which causes pain.

Spinal ligaments can thicken (ligamenta flava) [24] [25] Bone spurs develop on the bone and into the spinal canal or foraminal openings; Intervertebral discs may bulge or herniate into the canal or foraminal openings [26] Degenerative disc disease causes narrowing of the spaces. [27] Facet joints break down; Facet joints may hypertrophy [28]
Dural ectasia is defined as a ballooning or outpouching of the dura with a dural volume greater than two standard deviations above the mean value in controls. [9] It is usually identified by MRI or CT Scan, [7] which can be used to distinguish it from tumors. [16]
