Abstract
After approval of institutional ethical committee of faculty of medicine – Minia University (No. 349:11/2019) and written informed consent from the patients, this prospective randomized study was conducted on 40 adult patients of both sex with moderate to severe sacroiliitis who were resistant to conservative treatment, in the period from October 2019 to March 2020 at the pain management unit of Assuit University Hospital.
This study aimed to evaluate sacroiliac joint injection with local anesthetic and corticosteroid using the ultrasound and comparing it to the fluoroscopic guided injection.
Patients included in the study were randomly allocated into two equal groups (20 patients in each one ):
US Group: were treated with sacroiliac joint injection of local anesthetic and corticosteroid using the ultrasound.
FL Group: were treated with sacroiliac joint injection of local anesthetic and corticosteroid using the fluoroscopy.
All patients were followed up along a period of 3 months by using these parameters:
1. Visual analogue score (VAS) pain scores: assessed pre-procedure (baseline), during the procedure and 24 hrs., 72 hrs., 1 week, 1 and 3 months post-procedure.
2. Oswestry Disability Index (ODI) score (%) (Pain and physical function): assessed pre-procedure (baseline) and 1 month post-procedure.
3. Medical history: chronic illness, affected side and complaint duration (months).
4. Analgesic requirement: assessed pre-procedure (baseline) and 1 month post-procedure.
5. Procedure time (seconds).
6. Procedure discomfort (VAS).
7. Overall patient satisfaction: post-procedure, it was assessed using global perceived effect on a 7-point scale after performing the procedure.
8.Global evaluation of the therapy: it was assessed as the reduction in the VAS by more than 50% from the baseline. It was assessed at all follow up times after the procedure.
9. Success of the procedure: it was assessed according to the analgesic requirement post-procedure. If the pain was controlled with the injection and no need for analgesic, the procedure was successful but if the patient continued on the analgesic due to pain, it failed.
10. Any complication related to the SIJ injection along the period of follow up.
The results of the study revealed no significant difference between the two groups as regard demographic data or characteristic of the disease.
The two studied groups recorded significant improvement in VAS and ODI score (pain and function) in comparison to the pretreatment without significant difference between the two groups at all follow up points.
This improvement was maximum at 1st and 3rd months in both groups.
The results revealed significantly high patient satisfaction and lower analgesic requirement in both groups without any notable adverse effects.
Thus, the sacroiliac joint injection by using either the ultrasound or the fluoroscopy is effective, safe and give pain relief in patients with chronic sacroiliitis.
