Sacroiliac Joint Anatomy
The sacroiliac (SI) joint is a strong, synovial joint located between the sacrum and the ilium, which is the largest bone of the pelvis. It is a crucial weight-bearing joint that transmits forces between the spine and the lower extremities.
The SI joint is formed by the auricular surfaces of the sacrum and the ilium. The auricular surfaces are covered with a thin layer of cartilage, which provides a smooth surface for movement. The joint is surrounded by a number of ligaments, including the anterior sacroiliac ligament, the posterior sacroiliac ligament, and the interosseous sacroiliac ligament.
These ligaments help to stabilize the joint and prevent excessive movement.
The SI joint is also surrounded by a number of muscles, including the gluteus maximus, the gluteus medius, and the piriformis. These muscles help to control movement of the joint and provide stability.
Surrounding Bones, Si joint x ray oblique
The SI joint is formed by the sacrum and the ilium. The sacrum is a triangular bone located at the base of the spine. It is composed of five fused vertebrae. The ilium is the largest bone of the pelvis.
It forms the lateral and anterior walls of the pelvis.
Surrounding Ligaments
The SI joint is surrounded by a number of ligaments, including the anterior sacroiliac ligament, the posterior sacroiliac ligament, and the interosseous sacroiliac ligament.
Si joint x ray oblique is a diagnostic imaging technique that helps to visualize the sacroiliac joint. This joint is located between the pelvis and the spine, and it can be a source of pain and discomfort. If you are experiencing pain in your lower back or pelvis, your doctor may recommend a si joint x ray oblique to help determine the cause.

- The anterior sacroiliac ligament is a thick, fibrous ligament that runs from the anterior surface of the sacrum to the anterior surface of the ilium.
- The posterior sacroiliac ligament is a thick, fibrous ligament that runs from the posterior surface of the sacrum to the posterior surface of the ilium.
- The interosseous sacroiliac ligament is a thin, fibrous ligament that runs between the sacrum and the ilium.
Surrounding Muscles
The SI joint is surrounded by a number of muscles, including the gluteus maximus, the gluteus medius, and the piriformis.
- The gluteus maximus is a large, powerful muscle that covers the buttocks. It extends from the sacrum and the ilium to the femur.
- The gluteus medius is a thick, triangular muscle that lies deep to the gluteus maximus. It extends from the ilium to the femur.
- The piriformis is a small, pear-shaped muscle that lies deep to the gluteus medius. It extends from the sacrum to the femur.
Oblique X-Ray Views
Oblique x-ray views are crucial in assessing the sacroiliac joint, providing unique perspectives not captured by anteroposterior views.
Oblique views are taken at an angle to the joint, allowing for visualization of the joint surfaces in different planes. This helps in identifying abnormalities or changes in the joint structure that may not be visible on anteroposterior views alone.
Interpretation of Oblique Views
- Anterior Oblique View:This view shows the joint from the front and slightly to the side. It allows for assessment of the anterior aspect of the joint, including the iliac and sacral articular surfaces, as well as the anterior sacroiliac ligaments.
- Posterior Oblique View:This view shows the joint from the back and slightly to the side. It provides visualization of the posterior aspect of the joint, including the posterior sacroiliac ligaments and the relationship between the sacrum and ilium.
Diagnostic Features
Oblique x-rays of the sacroiliac joint provide valuable information for diagnosing disorders affecting this joint. Key diagnostic features include:
Subluxation:Displacement of the sacrum relative to the ilium, indicating instability or ligamentous injury.
Sclerosis:Increased bone density, often seen in degenerative conditions such as osteoarthritis.
Erosions:Areas of bone loss, indicative of inflammatory processes like ankylosing spondylitis.
Ankylosis:Fusion of the sacroiliac joint, resulting in loss of mobility.
Signs and Symptoms of Sacroiliac Joint Disorders
Patients with sacroiliac joint disorders may experience a range of symptoms, including:
- Low back pain that radiates to the buttocks or legs
- Pain that worsens with prolonged sitting or standing
- Stiffness and reduced range of motion in the lower back
- Tenderness over the sacroiliac joint
Interpretation and Reporting: Si Joint X Ray Oblique
Interpretation of oblique x-rays of the sacroiliac joint involves assessing joint alignment, symmetry, and any abnormalities. These x-rays provide valuable information about the joint’s structure and can aid in diagnosing conditions affecting it.
Assessment Criteria
The following criteria are used to assess oblique x-rays of the sacroiliac joint:
- Joint Alignment:The joint should be aligned in a relatively straight line, with the sacrum and ilium meeting at a smooth and congruent surface.
- Symmetry:The joint should be symmetrical on both sides, with similar appearances and dimensions.
- Abnormalities:Any deviations from normal alignment, symmetry, or the presence of any lesions, erosions, or sclerosis should be noted.
Interpretation
Based on the assessment criteria, oblique x-rays of the sacroiliac joint can be interpreted as follows:
- Normal:The joint is aligned, symmetrical, and free of any abnormalities.
- Abnormal:Deviations from normal alignment, symmetry, or the presence of abnormalities may indicate underlying conditions, such as sacroiliitis, osteoarthritis, or other joint disorders.
Differential Diagnoses
Oblique x-rays of the sacroiliac joint can reveal a variety of abnormalities, including inflammation, erosion, and sclerosis. These findings can be indicative of several conditions, including sacroiliitis, osteoarthritis, and ankylosing spondylitis.
Sacroiliitis is a condition characterized by inflammation of the sacroiliac joint. It can be caused by a variety of factors, including infection, trauma, and autoimmune disorders. Oblique x-rays of the sacroiliac joint may show evidence of inflammation, such as swelling and tenderness.

Additional Imaging Modalities
While plain radiography provides a useful initial assessment of the sacroiliac joint, advanced imaging modalities like computed tomography (CT) and magnetic resonance imaging (MRI) offer more detailed information.
CT scans excel in visualizing bony structures, including the sacroiliac joint and surrounding vertebrae. They can detect subtle fractures, sclerosis, and erosions that may not be apparent on X-rays. However, CT scans have limited soft tissue contrast, making them less effective for evaluating ligamentous injuries or inflammatory changes.
MRI, on the other hand, excels in visualizing soft tissues. It can clearly depict the sacroiliac ligaments, muscles, and nerves, allowing for the assessment of ligamentous tears, muscle strains, and nerve entrapment. MRI also provides excellent contrast between different tissues, making it useful for identifying inflammatory changes and differentiating between various pathologies.
Advantages and Disadvantages
- X-ray:Cost-effective, widely available, provides a good overview of bony structures, but limited soft tissue visualization.
- CT:Detailed bony visualization, can detect subtle fractures and erosions, but limited soft tissue contrast.
- MRI:Excellent soft tissue visualization, can assess ligaments, muscles, and nerves, but more expensive and less widely available.
