Does Injection Target Matter in Sacroiliac Joint Dysfunction?
Sponsor: Fatih Sultan Mehmet Training and Research Hospital
Summary
This retrospective comparative cohort study aims to compare the short-term clinical outcomes of ultrasound-guided sacroiliac joint (SIJ) injection, combined SIJ and multifidus injection, and multifidus injection alone in patients with sacroiliac joint dysfunction. Medical records of patients who underwent ultrasound-guided injection procedures were retrospectively reviewed and classified into three groups according to the documented injection target: SIJ injection alone, combined SIJ and multifidus injection, and multifidus injection alone. The primary outcome is the change in pain intensity during movement, assessed using the Visual Analog Scale (VAS) from baseline to 30 minutes after injection. Pain outcomes at one week and changes in functional measures, including the Roland-Morris Disability Questionnaire and Oswestry Disability Index, are evaluated as secondary outcomes. The study aims to determine whether short-term pain and functional outcomes differ according to the injection target.

Interventions
Ultrasound-Guided Sacroiliac Joint Injection
Ultrasound-guided intra-articular sacroiliac joint injection was performed with the patient in the prone position. The sacroiliac joint and surrounding vascular structures were identified using ultrasonography and color Doppler imaging. A 22-gauge, 3.5-inch spinal needle was advanced toward the sacroiliac joint under ultrasound guidance. After confirming the absence of intravascular placement, 2.0 mL of 2% lidocaine was administered intra-articularly.
Ultrasound-Guided Multifidus Injection
Ultrasound-guided intramuscular multifidus injection was performed with the patient in the prone position. After ultrasonographic identification of the relevant sacral anatomical landmarks and the multifidus muscle, a 22-gauge, 3.5-inch spinal needle was advanced into the multifidus muscle under ultrasound guidance. After confirming the absence of intravascular placement, 2.0 mL of 2% lidocaine was administered intramuscularly.
