Sacroiliac Joint Injection
Nashaat N. Rizk
Albert J. Carvelli
Patient Position: Prone on the fluoroscopy table.
Indications: Sacroiliac pain syndrome.
Needle Size: 22-gauge, 88-mm spinal needle.
Medication/Volume: 0.5% bupivacaine 2 mL plus 40 mg methylprednisolone.
Anatomic Landmarks: Posterior superior iliac spine and sacrum.
Approach and Technique: After sterile preparation of the region, the sacroiliac joint is identified under fluoroscopy in the anteroposterior view (Fig. 70-1A).
To gain access to this joint space, the fluoroscopic beam must be
rotated approximately 15° to 30° to the opposite side of the joint to
locate the posterior face of the sacroiliac joint, and then 20° to 30°
cephalad and caudad (Ferguson view; Fig. 70-1B).
Two separate injections can be performed. The first injection is aimed
at the inferior one-third of the joint. Accordingly, the 22-gauge
spinal needle is aimed in the same direction as the fluoroscopic beam
to gain access to the joint. A loss of resistance is often felt as the
joint space is entered. Next, the superior one-third of the joint space
is entered in a similar fashion. To help confirm the joint space
location, 0.5 to 1.0 mL of contrast dye can be injected prior to the
injection of the local anesthetic mixture.
Tips
  • The feeling of a “pop” or loss of
    resistance when advancing the needle can be misleading. The joint space
    itself can be difficult to enter with the needle. Always reconfirm the
    correct positioning of the needle with fluoroscopy.
