Primary outcomePrimary: Intravascular Uptake — 5.9; 7.1 percentage of total number of needle
Summary
The aim of the study was to quantify the difference between a 22-gauge needle and 25-gauge needle during lumbosacral epidural steroid injection in regards to intravascular uptake and pain perception. There is the notion that a smaller gauge needle may lead to less intravascular uptake and less pain.
