Injections for pain in lower back and buttocks

What is it?

What is it?

The sacroiliac joint (SIJ) is the joint between the sacrum and the ilium bones. Due to wear and tear (arthrosis), inflammation, surgery or an accident, the SI joint area may undergo change. This may result in pain in the lower back and buttocks. The pain may also manifest on one side only.

An SIJ infiltration involves injecting a local painkiller and an anti-inflammatory agent (cortisone) in the area near the painful joint. Cortisone reduces the inflammatory response and this will eventually cause the pain to decrease.

If you experience a clear reduction in pain but only for a brief period, denervation (radiofrequency treatment) of the sacroilial joint may be considered. This treatment involves ‘facet joint denervation‘.

Preparation

Come to the hospital on the day of treatment.
You do not need to be fasting for the treatment. You may eat and drink.

By law, you may not drive any vehicles or operate machinery the morning after the treatment. Therefore, make sure that somebody can take you to and from the hospital. The physician or nurses can provide you with certificates, if required. If you wish, the nurses of the Pain Centre can order a taxi for you.

Always inform the physician if:

  • you have diabetes or a heart condition
  • you are (or could be) pregnant
  • you are allergic to certain medications, contrast agents or iodine (disinfectant), latex, etcetera
  • you take blood thinners

If you have reduced kidney function, have recently experienced thrombosis or a heart attack or have had a stent implanted, you must contact your attending physician first.
