Corticosteroid injection of the sacroiliac joint in patients with seronegative spondylarthropathy.

OBJECTIVE: We report our experience with the use of corticosteroid injections into the sacroiliac joint in the treatment of patients with seronegative spondylarthropathy.

METHODS: We performed 42 injections, constituting 24 procedures in 22 patients (2 patients had the procedure performed twice).

RESULTS: The response was considered very good or good in 19 of 24 procedures (79.2%) and 34 of 42 joints (81%). Improvement persisted in 14 patients after a mean +/- SD followup time of 9.6 +/- 4.2 months.

CONCLUSION: This technique appears to be safe, easy to apply into ambulatory patients, and quite effective.
