    Study Notes

    Sacroiliac Joint Anatomy and Biomechanics

    • The sacroiliac joint is a complex structure that plays a crucial role in maintaining pelvic stability and facilitating movement.
    • The joint is formed by the articulation of the sacrum and ilium bones, with a complex system of ligaments, muscles, and fascia providing support and stability.
    • The sacroiliac joint is capable of a wide range of movements, including flexion, extension, rotation, and counter-rotation.

    Sacral Motion

    • Sacral motion can be restricted in two ways: sacroiliac flexion restriction and sacroiliac extension restriction.
    • Sacroiliac flexion restriction is characterized by a decrease in post-inferior glide, rotation restriction around the right or left oblique axis (ROA or LOA), and counter-rotation malposition of the PS-SB.
    • Sacroiliac extension restriction is characterized by a decrease in post-inferior glide, rotation restriction around the left or right oblique axis (LOA or ROA), and counter-rotation malposition of the AI-SB.

    PI Ilium (Anterior Glide Restriction)

    • PI Ilium is a type of sacroiliac joint dysfunction characterized by an anterior glide restriction of the ilium.
    • It is more common than AS Ilium and is often associated with ipsilateral lumbar scoliosis.
    • Key findings include:
      • Low crest and PSIS on the same side as the ilium
      • High ASIS on the opposite side
      • Decreased prone thigh extension on the same side as the ilium
      • PSIS more pronounced on the same side as the ilium
      • PN in the lower half of the SI joint
    • Treatment involves prone sacroiliac extension palpation and mobilization to restore normal motion.

    AS Ilium (Posterior Glide Restriction)

    • AS Ilium is a type of sacroiliac joint dysfunction characterized by a posterior glide restriction of the ilium.
    • It is less common than PI Ilium and is often associated with contralateral lumbar scoliosis.
    • Key findings include:
      • High crest and PSIS on the same side as the ilium
      • Low ASIS on the opposite side
      • Increased prone thigh extension on the same side as the ilium
      • PSIS less pronounced on the same side as the ilium
      • PN in the lower half of the SI joint
    • Treatment involves prone sacroiliac flexion palpation and mobilization to restore normal motion.

    Sacroiliac Joint Syndrome/Dysfunction

    • Sacroiliac joint syndrome is a condition characterized by aberrant motion of the sacroiliac joint, leading to pain and dysfunction.
    • It can be caused by a variety of factors, including hypomobility, ligamentous laxity, and trauma.
    • Key findings include:
      • Local pain that may radiate into the lower back and buttocks
      • Dull ache to sharp and stabbing pain
      • Provocative factors include weight-bearing, sit-to-stand, motion, and pelvic flexion/extension
      • Palliative factors include recumbency (lying down)
    • Treatment involves a combination of manual therapy, exercise, and education to restore normal motion and reduce pain and dysfunction.

    Sacroiliac Joint Syndrome - History

    • A thorough history is essential in diagnosing sacroiliac joint syndrome.
    • Key questions to ask include:
      • Where is the pain located?
      • What is the nature of the pain?
      • Are there any provocative or palliative factors?
      • Are there any associated symptoms, such as numbness, tingling, or weakness?

    Sacroiliac Joint Syndrome - Findings

    • Key findings include:
      • Local pain and tenderness
      • Leg length inequality
      • Possible gait abnormalities
      • Palpation of misalignment or restricted motion/joint play (hard end feel)
      • Postural abnormalities

    Sacroiliac Joint Special Test Cluster

    • A special test cluster is a group of tests used to diagnose sacroiliac joint syndrome.
    • The cluster includes:
      • Distraction test
      • Compression test
      • Thigh thrust test
      • Sacral thrust test
      • Gaenslen's test
    • Each test is designed to assess a specific aspect of sacroiliac joint function and can help diagnose sacroiliac joint syndrome.

    Benefits of Using Orthopedic Test Clusters

    • Using orthopedic test clusters has several benefits, including:
      • Increased accuracy in diagnosis
      • Improved treatment outcomes
      • Reduced risk of misdiagnosis
      • Improved patient satisfaction
    • However, there are also some drawbacks, including:
      • Limited evidence supporting the use of some tests
      • Variability in test performance and interpretation
      • Risk of over-testing or under-testing

    Sacroiliac Joint Anatomy and Biomechanics

    • Sacroiliac joint is a dynamic L-S joint that plays a crucial role in maintaining pelvic stability and facilitating movement
    • The joint is composed of sacrum and ilium bones, with a complex system of ligaments, muscles, and nerves that provide stability and facilitate movement

    Sacral Motion

    • Sacral motion can be restricted in two ways: sacroiliac flexion restriction and sacroiliac extension restriction
    • Sacroiliac flexion restriction is characterized by decreased lordosis, open packed position of the facets, and decreased post-inferior glide of the ilium
    • Sacroiliac extension restriction is characterized by increased lordosis, closed packed position of the facets, and decreased post-inferior glide of the sacrum

    PI Ilium and AS Ilium

    • PI Ilium is a type of sacroiliac joint dysfunction characterized by an anterior glide restriction of the ilium
    • AS Ilium is a type of sacroiliac joint dysfunction characterized by a posterior glide restriction of the ilium
    • Both PI Ilium and AS Ilium can cause leg length inequality, lumbar scoliosis, and altered gait patterns

    Sacroiliac Joint Syndrome

    • Sacroiliac joint syndrome is a condition characterized by pain and dysfunction in the sacroiliac joint
    • The condition is often caused by aberrant motion of the sacroiliac joint, which can lead to pain, inflammation, and instability
    • Sacroiliac joint syndrome can be caused by hypomobility, ligamentous laxity, pregnancy, trauma, and leg length inequality

    Orthopedic Tests for Sacroiliac Joint Syndrome

    • Orthopedic tests are used to diagnose sacroiliac joint syndrome and distinguish it from other conditions
    • The tests include distraction, compression, thigh thrust, sacral thrust, and Gaenslen's test
    • Each test is designed to assess specific aspects of sacroiliac joint function and identify patterns of pain and dysfunction

    Sacroiliac Joint Special Test Cluster

    • The sacroiliac joint special test cluster is a group of orthopedic tests used to diagnose sacroiliac joint syndrome
    • The tests in the cluster are designed to be used in combination to provide a more accurate diagnosis
    • The cluster includes distraction, compression, thigh thrust, sacral thrust, and Gaenslen's test

    Advantages and Disadvantages of Orthopedic Test Clusters

    • Advantages of using orthopedic test clusters include increased accuracy, improved diagnostic reliability, and better patient outcomes
    • Disadvantages of using orthopedic test clusters include potential for false positives, complexity of test administration, and need for specialized training

    Sacroiliac Joint Syndrome: History and Physical Examination

    • Patients with sacroiliac joint syndrome often report local pain that may radiate into the lower back and buttocks
    • Pain patterns are variable and can include dull ache, sharp stabbing pain, and numbness or tingling
    • Provocative factors include weight-bearing, sitting, standing, and motion
    • Palliative factors include recumbency (laying down)

    • Grade 1: mild, characterized by less than 10% fiber damage
    • Grade 2: moderate, characterized by 10-50% fiber damage
