Purpose: To assess the feasibility of ultrasound (US) guided injections in the sacroiliac joint.
Methods and Materials: US-guided 22 sacroiliac joint injections were performed in 11 human cadavers. US was performed with a 2.5 MHz curved array transducer (Esaote Technos MPX or Acuson Sequoia 512). 22-gauge spinal needles were used for injections. We injected 1ml nonionic contrast material (Iomeron, Bracco). Three different transverse scanning approaches for needle placements (1. level of L5; 2. level of S1, and 3. level of S2) were evaluated. Computed tomography (CT) was used to confirm the proper placement of the injections.
Results: Of 22 sacroiliac joint injections, 17 (77%) were intraarticular. The injections were repeated in 10 (45%) sacroiliac joints under CT guidance because of improper needle placement. The highest success rate was found using the most caudal (level of S2) approach.
Conclusion: Our preliminary findings suggest that US-guided injection using the most caudal located approach (level of S2) is an appropriate method for sacroiliac joint injection.
