Sacroiliac Joint Dysfunction Quiz

Abnormal function of the sacroiliac joint (SIJ), often due to altered mechanics, leading to pain and discomfort.

Five fused sacral vertebrae forming a triangular bone supporting the spine.

The first sacral segment (S1) attaching to the lumbar vertebrae, creating a sixth lumbar vertebra.

The fifth lumbar segment fuses to the sacrum or ilium, resulting in a reduced number of lumbar vertebrae.

The angle formed between the superior aspect of the sacrum and a horizontal line.

Articulation between the sacrum and the ilium of the pelvis.

Surface of the sacrum in the SIJ, shaped like a 'C' and covered with hyaline cartilage.

Surface of the ilium in the SIJ, covered with fibrocartilage.

A condition where one side of the pelvis tilts, with the ASIS (anterior superior iliac spine) lower and the PSIS (posterior superior iliac spine) higher, due to abnormal movement in the sacroiliac joint.

The fit between the bones, independent of external forces, that contributes to joint stability.

External forces, like muscle contractions, that contribute to joint stability.

The force of body weight pulling the sacrum forward, creating a tendency for the sacrum to tilt forward, resulting in nutation.

The ligamentous network and surrounding muscles that reinforce the sacroiliac joint, contributing to its stability.

Tense hip flexors and extensors, particularly tight psoas and rectus femoris muscles, can contribute to SIJ dysfunction.

A difference in leg length can create uneven pressure on the sacroiliac joints, leading to dysfunction.

A group of muscles that act together to stabilize the lumbar spine and pelvis. It includes the external obliques, internal obliques, transverse abdominals, and contralateral adductors of the thigh.

Pain stemming from the sacroiliac joint (SIJ), often characterized by deep, dull, and undefined pain that tends to be on one side of the body.

A condition where the leg on one side appears longer than the other. It's caused by a difference in the lengths of the bones in the legs, leading to asymmetry and pain.

A condition where the legs seem to be different lengths even though the bones are actually the same size. It's caused by other factors, like uneven positioning of the pelvis.

A condition where the sacroiliac joint (SIJ) is overly stressed, often due to factors like pregnancy or excessive pronation of the feet.

A medical procedure used to assess the functionality of the sacroiliac joint (SIJ). It involves examining the joint's range of motion, stability, and pain response to specific movements.

A type of medical assessment that involves applying pressure or force to the sacroiliac joint (SIJ) to determine pain levels and identify potential sources of discomfort.

A common symptom of SIJ dysfunction, where the pain is worse when standing or walking for extended periods, particularly on one side.

A test that assesses sacroiliac joint mobility by observing the movement of the posterior superior iliac spine (PSIS) as the patient flexes their hip.

This test specifically evaluates the sacrum's movement relative to the ilium, eliminating lower extremity influence. This is done by having the patient sit and flex their spine.

Also known as the ipsilateral posterior rotation test, this test examines the ilium's mobility by observing the movement of the PSIS with hip abduction and external rotation. The examiner places their thumb on the PSIS and observes its movement.

The examiner's thumb placed on the PSIS moves upward if the SI joint is fixed, indicating limited mobility. However, with normal movement the thumb should move downward.

A test involving hip flexion, adduction, and internal rotation for assessing the sacroiliac joint.

A diagnostic maneuver to assess the stability of the SI joint by applying outward and downward pressure on the anterior superior iliac spines (ASISs).

Pain experienced unilaterally at the SI joint or in the gluteal region during the anterior gapping test, suggesting an anterior SI ligament sprain.

An extension, side bending, and rotation of the spine to the affected side while the examiner provides overpressure through the shoulders.

A mobilization technique that uses the patient's own muscles to create a specific movement in the sacroiliac joint. It aims to restore mobility, reduce pain, and improve joint function.

A manual therapy technique that involves gentle, sustained pressure applied to a joint to improve movement and reduce pain.

A more forceful technique used to restore joint motion to the Sacroiliac joint. It aims to improve joint mechanics and reduce pain.

Stretching techniques targeting muscles around the Sacroiliac joint. It helps to reduce muscle tightness, improve flexibility, and reduce pain.

Exercises that strengthen the core muscles - abdominal, back, and pelvic floor muscles - to improve stability and reduce stress on the SIJ.

A mobilization technique that involves gliding the ilium (hip bone) posteriorly to correct a forward rotation of the joint. Helps restore normal alignment.

A mobilization technique that involves gliding the ilium (hip bone) anteriorly to correct a backward rotation of the joint. Also helps restore normal alignment.

A graded approach to joint mobilizations. Grade I uses small movements, Grade II uses larger movements, and Grade III and IV involve large movements at the end range to improve motion and reduce pain.

A test for sacroiliac joint problems. The patient lies on their side with the examiner applying downward pressure on the iliac crest. Pain suggests SI joint dysfunction.

A test used to assess sacroiliac joint dysfunction. The patient lies on their back while the examiner applies inward and downward pressure to the iliac crests. Pain suggests SI joint involvement.

A test for assessing hip and sacroiliac joint mobility. The patient lies on their back while the examiner flexes, abducts, and externally rotates the patient's leg. If the leg doesn't abduct to the same level as the other side, it may indicate iliopsoas tightness or sacroiliac joint problems.

This test involves a patient pulling one knee to their chest while the examiner applies downward pressure on the other leg, forcing it into hyperextension. Pain in the SI region indicates SI joint dysfunction.

A system that uses signs, symptoms, and findings to predict the probability of a specific condition, like SI joint dysfunction. It helps determine the likelihood of a condition based on physical assessments.

A group of tests that have high sensitivity and specificity for detecting sacroiliac joint dysfunction. Three or more of these tests together indicate a higher likelihood of SI joint problems.

A condition affecting the sacroiliac joint, leading to pain and discomfort.

A ligament located at the posterior of the sacroiliac joint. This ligament helps stabilize the SI joint.
