Injections for Pelvic or Sacral Pain

ABSTRACT

Patients with pelvic or sacral pain can be easily encountered in outpatient clinic settings. Since the cause of pain can be originated from the lumbar spinal region, or sometimes directly from the pelvis or sacral region, it is essential to differential diagnose where the pain is coming from. Caudal epidural steroid injection, sacroiliac joint injection, and piriformis injection are not only therapeutic, but are often used diagnostically, therefore they would be more useful in the outpatient clinic.Ultrasound-guided injections have similar clinical effects and the advantage of having shorter procedure times and no radiation exposure compared with fluoroscopic image-guided injection. Therefore, it is recommended to safely perform pelvic or sacral injections using ultrasound guidance.
