What is being measured
The primary outcome is the main question the study is designed to answer.
Number of participants who experience complications over time
Any complication, including but not limited to infection or wound healing complications
Measured: 6 months
Change in pain score over time as measured on a pain scale
Scored from 0-10 (higher scores indicate worse pain)
Measured: 6 months
Change in cosmetic appearance over time as measured by the Oxford Finger Nail Appearance Score
Oxford Finger Nail Appearance Score (OFNAS), ranges from 0 to 5 (5 is the best appearance)
Measured: 6 months
Change in upper extremity function over time as measured by the QuickDash score
Quick Disabilities of Arm, Shoulder, \& Hand (QuickDASH) score, ranges from 0 (no disability) to 100 (most severe disability)
