| Measure | Description | Time Frame |
|---|---|---|
| Performance time | 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. | Duration of procedure (less than 20 minutes) |
| Measure | Description | Time Frame |
|---|---|---|
| Change in pain numerical rating score from baseline | 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. | Baseline and 20 minutes after procedure |
