OBJECTIVE: The purpose of this prospective study was to determine the conditions under which intra-articular injection therapy may be superior to nonsteroidal anti-inflammatory drugs (NSAIDs) in patients with sacroiliac joint pain in the outpatient setting at our hospital.

PATIENTS AND METHODS: Patients with sacroiliac pain were divided into two groups: NSAID and the sacroiliac injection group. The NSAID group received 25 mg of indometacin orally once a day and 750 mg of naproxen orally once a day. In the sacroiliac injection group, 5 mg of betamethasone were injected into the sacroiliac joint. The patients’ history of lumbar surgery, whether they had sacroiliitis, and the duration of pain were recorded. The patients’ VAS (Visual analogue scale) scores at week 1 and month 1 were evaluated.

RESULTS: VAS scores were decreased after the first week and first month in the sacroiliac injection group compared to the NSAID group (p<0.001). Sacroiliac steroid injection was found to be superior to NSAIDs in reducing VAS scores in patients with sacroiliitis, a history of lumbar surgery, and pain lasting more than 30 days (p<0.001). In patients without sacroiliitis, without a history of lumbar surgery, and with less than 30 days of pain, no difference was observed between the groups in reducing VAS scores at the end of the first month.

CONCLUSIONS: In patients with sacroiliac joint pain, sacroiliac joint injection is superior to NSAIDs in pain relief in patients with pain for more than 30 days, those with MRI-diagnosed sacroiliitis, and those who have undergone lumbar surgery.
