Overview
Brief Summary
This study aims to compare the effectiveness of the use of no topical anesthesia, topical coolant, and the use of vibration in the reduction of pain during trigger finger injections. This will be done by randomizing patients who are diagnosed with trigger finger, warrant and choose to continue with a steroid injection into each of the respective anesthetic (or lack thereof) methods described. After conducting this and gathering data on the subjects pain felt, we will compare the analgesia from each of the anesthetic methods.

Eligibility Criteria
Inclusion Criteria
- •Healthy Adult
- •Diagnosed with trigger finger
- •Warrants a trigger finger injection
Exclusion Criteria
- •Subjects with known decreased light touch sensation in the territory of the trigger finger injection.
- •Not diagnosed with trigger finger or does not warrant a trigger finger injection per the typical treatment algorithm adopted by the attending physician.
Arms & Interventions
Topical coolant
The subject will have 5 seconds of sterile ethyl chloride sprayed at the site of the trigger finger injections just prior to the administration of the injection.
Intervention: Gebauers Ethyl Chloride 100% Topical Spray
Vibration
The subject will have a vibration device placed just proximal to the site of the trigger finger injection concurrent with the administration of the injection.
Intervention: Vibration Anesthesia Device by Blaine Labs
Outcomes
Primary Outcomes
Pain Felt
Time Frame: Immediately after the trigger finger injection is completed
Visual Analog Pain Scale Rating (Hayes and Patterson 1921) Scale Title: Pain scale Maximum Value: 10 - The worst pain Minimum value: 0 - No pain \*A lower number indicates a better outcome (less pain felt).
