BACKGROUND: Low back pain is a prevalent issue with various etiologies, one of which includes pars interarticularis (pars) defects. While traditional fluoroscopic guidance has been the standard for administering injections, both fluoroscopic and ultrasound-guided injections for the management of low back pain have been shown to be similar in efficacy. The benefits of ultrasound guidance include real-time visualization, reduced radiation exposure, and improved patient access.

CASE REPORT: A 51-year-old active man with chronic low back pain underwent bilateral pars injections using ultrasound guidance. Ultrasound and fluoroscopic imaging confirmed accurate needle placement. The patient’s history indicates that the injections resulted in significant pain relief, which was sustained at the 3-month follow-up.

CONCLUSIONS: This is a technical description of an ultrasound-guided pars injection, which can be used as an alternative to fluoroscopic-guided injection.
