Sacroiliac Joint Injection Proposal

Given that I do not have Ultrasound (got rid of old one – filled a room), I have developed a SI joint technique and would like opinion re such. Also I will refer to article using SI injections.

Short-term efficacy of sacroiliac joint corticosteroid injection based on arthrographic contrast patterns.

• Fluoroscopically guided corticosteroid injections of  49 cases.
• Besides dye, injected 1 mL of 2% preservative-free lidocaine
  hydrochloride and  1 mL of triamcinolone acetonide 40 mg.

Preferred 3 positive SI provocation tests Brief review:

• Usually like to see 3 positive tests
• Usual lower joint technique is to inject in the buttock along canal line (see picture)
• Without imaging, I find it easier to inject going in near sacral hiatus and angle under the posterior inferior spine, following the direction of the SI joint as seen in picture. I inject 40 mg kenalog.

• It must be a great surprise to some to consider that the sacroiliac ligaments are painful as well, and I inject any tender ligaments found after the SI injection with 20 mg kenalog… I use a 22 gauge 3 1/2″ spinal needle and keep the trocar in place until under skin – to avoid “punch biopsying” a piece of skin into joint

Any comments on technique?

addendum – old procedure
