Pelvic Pathology Sacroiliac Joint Sacro-iliitis physical therapy movies. In ankylosing spondylitis, inflammation of the sacroiliac joint, known as sacroiliitis, is the same on both sides, although it may be asymmetric in the early stages of the disease. It is progressive over years. The synovial part of the sacroiliac joint is most severely affected.
The normal sacroiliac synovial joint has a smooth cartilage surface with uniform underlying bone density.
Inflammation of the sacroiliac joint leads to bone edema or osteitis, an inflamed joint capsule (capsulitis) and synovial membrane (synovitis) and inflamed ligament attachment points (enthesitis), with mild generalized resorption of the adjacent bone.
This can progress to joint cartilage destruction and irregular focal erosions of the underlying bone. Erosions of the bone of the sacroiliac joint are generally seen earlier in the lower portion of the joint. Pelvic Pathology Sacroiliac Joint Sacro-iliitis physical therapy movies.
