Pain originating from the sacroiliac joint, often due to hypermobility or inflammation.
✦ AI summary
Here's what these sources say about sacroiliac (SI) joint dysfunction:
**How common and how it's diagnosed:** SI joint dysfunction is thought to affect 15%-30% of people with nonspecific low back pain and is a significant issue even among nurses themselves [1]. Diagnosis can be tricky since no single test is perfect — one study found that a numbing injection into the joint gave immediate relief in most people, but checking whether relief lasted a full week gave a much more accurate picture, since immediate relief alone was often misleading [6]. Researchers are also studying the ligament structure connecting the sacrum and pelvis, hoping this could eventually improve imaging-based diagnosis [11].
**Conditions that can mimic it:** Several sources describe other problems that can look like SI joint dysfunction, including a rare bone tumor (osteoblastoma) that delayed proper treatment in one patient who wasn't improving with standard care [4], a rare form of sarcoidosis affecting the joint that mimicked cancer or joint inflammation on scans [2], and upper lumbar disc disease causing buttock pain that was initially mistaken for SI joint or piriformis problems [10].

What You Need to Know About Sacroiliac Dysfunction.
Low back pain is the leading cause of disability worldwide, and sacroiliac dysfunction is estimated to occur in 15%-30% of those with nonspecific low back pain. Nurses are in the unique position to support and provide education to patients who may be experiencing sacroiliac dysfunction or possibly a…
Unveiling the unexpected: Skeletal sarcoidosis with an extraosseous soft-tissue mass in the ligamentous portion of sacroiliac joint.
Sarcoidosis is a chronic granulomatous, multisystem disease of uncertain etiology that affects various organ systems, although musculoskeletal involvement is rarely the dominant feature. We present the case of a woman in her 50s with a history of pulmonary sarcoidosis who developed new lower back an…
Defining and validating a high specificity MRI cut-off for the radiographic part of the modified New York criteria in patients with axial spondyloarthritis.
According to the modified New York criteria (mNYc), moderate-severe sacroiliac joint (SIJ) structural damage on radiography is necessary for classifying radiographic axial spondyloarthritis (r-axSpA). In contrast to radiography, MRI provides no ionizing radiation, higher sensitivity for structural d…
Fragility Score in Radiographic Axial Spondyloarthritis Assessed with Radiofrequency Echographic Multi-Spectrometry (REMS).
Axial spondyloarthritis (axSpA) is a chronic inflammatory disease affecting the sacroiliac joints and spine and is associated with an increased risk of fractures due to persistent inflammation, reduced mobility and treatment-related factors. In radiographic axSpA (r-axSpA), assessment of bone minera…
Clinical Utility of Repeat Sacroiliac Joint MRI in Patients Evaluated for Axial Spondyloarthritis: A Real-World Cohort Study.
Objectives: To evaluate the real-world diagnostic and therapeutic impact of repeat sacroiliac joint magnetic resonance imaging (SIJ MRI) in patients undergoing assessment for axial spondyloarthritis (axSpA). Methods: This retrospective study included patients who underwent at least two SIJ MRI exami…
Role of MRI-based synthetic CT and low-dose CT for the assessment of structural damage in axial spondyloarthritis - a review.
Structural lesions, including erosions, sclerosis, and pathological new bone formation, are key features of disease progression in axial spondyloarthritis (axSpA) and are associated with irreversible functional impairment. Reliable imaging methods are therefore essential for accurate assessment and…
Spondyloarthritis Inception Cohort of Southern Denmark (SPINCODE): a protocol for a single centre prospective observational cohort study in patients suspected of axial spondyloarthritis.
Spondyloarthritis (SpA) comprises a heterogeneous group of chronic inflammatory diseases. Axial SpA (axSpA) predominantly involves the sacroiliac joints and the spine and typically presents with back pain and stiffness. Modern imaging techniques, especially MRI, allow earlier detection of axSpA comp…
Significance of fiber orientation in the interosseous sacroiliac ligament: An anatomical and histological study of the implications of its mechanical adaptation.
The sacroiliac joint allows limited but crucial movement for transmitting loads from the spine to the pelvis. Identifying anatomical structures that adapt to this motion may improve imaging-based diagnosis of sacroiliac joint dysfunction. The interosseous sacroiliac ligament (ISIL), a key stabilizer…
