Back Pain
Conditions
Brief summary
Sacral lateral branch blocks are used for the diagnosis and treatment of sacroiliac joint pain. This study will compare ultrasound and fluoroscopy guidance for sacral lateral branch blocks. Outcomes examined will include performance times and success rates.
Interventions
This group will be treated using an ultrasound imaging device

Eligibility
Inclusion criteria
* Any consenting patient over 18 years of age, undergoing a diagnostic sacral lateral branch block for suspected sacroiliac joint related pain.
Exclusion criteria
* Inability to consent, iodine or lidocaine allergy, pregnancy, coagulopathy (as defined by an international normalized ratio over 1.4, platelets under 100,000, or a documented bleeding disorder) and inability to visualize the target areas necessary for sensory testing (posterior superior iliac spine, dorsal aspect of SIJ) under ultrasound guidance.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Performance time | Duration of procedure (less than 20 minutes) | Block performance time will be measured from the time the first image is acquired, until the last injection is completed. Typical performance time are expected to be less than 20 minutes for both groups. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in pain numerical rating score from baseline | Baseline and 20 minutes after procedure | The extent of anesthesia provided by the blocks will be assessed by probing structures known to be innervated by the lateral branches and L5 posterior root. Two pain measurements will be undertaken, before and 20 minutes after the injections. Pain reports will be quantified by using a numerical rating score. |
