Sacroiliac joint (SIJ) pain diagnosis involves a combination of methods to pinpoint the source of discomfort. This often requires a thorough approach because SIJ pain can mimic other conditions. According to the provided reference, the diagnosis of SIJ pain typically includes the following key components:
Diagnostic Methods for SIJ Pain
The diagnostic process often involves a combination of assessments to accurately determine if the SIJ is the source of pain. The primary methods are:
-
Physical Examination: This is the first step and involves a detailed assessment of the:
- Spine: The doctor will check for any abnormalities or pain points along the spine.
- Pelvis: A careful examination of the pelvic area, looking for tenderness or signs of inflammation.
- Hips: An evaluation of hip joint mobility and pain, to differentiate hip from SIJ issues.
-
Provocative Tests: These are specific physical maneuvers performed by a clinician to try and reproduce the patient's pain. By applying pressure or stress to the SIJ, the doctor can assess if it’s the pain generator. Examples include:
- Gaenslen's test: A test where one leg is extended off the table, and the other is pulled to the chest.
- FABER test: This is when the hip is flexed, abducted, and externally rotated to assess hip and SI joint problems.
- Thigh thrust test: Pressure is applied to the hip while the patient is lying down.
-
Diagnostic Injections: This is considered the most definitive diagnostic tool for SIJ pain.
- A local anesthetic is injected directly into the SI joint.
- If the pain significantly reduces after the injection, it strongly suggests the SIJ is the source of pain.
- This can help confirm or rule out the SIJ as a pain source and is helpful for treatment planning.
Summary of SIJ Diagnosis
In summary, diagnosing SIJ pain is a multifaceted process that includes physical exams, provocative tests, and diagnostic injections. It often requires a comprehensive evaluation to ensure an accurate diagnosis and treatment plan.
