Brief Summary
The purpose of the study is to determine the effectiveness of a new approach to numbing (anesthetizing) nerves in the back and to measure how far the area of anesthesia extends on the skin of the back.

Outcome Measures
Primary Outcomes (1)
Anesthesia (monitoring of pain, temperature, and adverse reaction to anesthesia [tinnitus, disorientation, or perioral numbness])
At time zero (pre injection), 5 minutes, and 15 minutes point-discrimination to pain and temperature will be evaluated by blunt-needle prick and ice (in plastic bag). A "map" of each will be drawn and photographed for analysis. 1. Photos will only include surface anatomy of the low-to-mid back. 2. Participants will be assessed for evidence of adverse reaction to local anesthesia (tinnitus, disorientation, or perioral numbness) with each 5cc dose of local anesthetic.

Study Arms (1)
Thoracolumbar Interfascial Plane Block
EXPERIMENTALAll participants will have two injections at the same vertebral level on each side of the back. Each injection will consist of four 5cc incremental injections with aspiration prior to each 5cc of injectate of 0.5% Ropivicaine. . Each side of the back will be injected with 20cc of .05% Ropivicaine. Ultrasound will be used in real time to guide the needle, evaluate for "spread" of local anesthesia and to minimize the risk of Ropivicaine being injected intravascularly. a. Ultrasound images will be saved using the nomenclature TLIP Anat

If any adverse reactions are noted the dosing will be stopped.
