Summary
A nerve block catheter is a small tube placed next to a nerve through a needle, and the
needle is then removed. Numbing medicine is dripped through the tube to reduce pain sensation
from the nerve.
The purpose of this research study is to test whether the placement of a second nerve block
catheter, rather than a single injection for the saphenous nerve block will improve pain
relief and/or reduce pain medication needed after surgery enough to justify two nerve block
catheters.
There are two nerves that carry pain sensations from the ankle, the large (sciatic) nerve and
the smaller (saphenous) nerve. Patients undergoing ankle fusion or fracture surgery at Wake
Forest University typically have a nerve block catheter placed next to the sciatic nerve to
give local anesthetic (numbing medicine) for 24-72 hours. In addition, a single injection of
local anesthetic is usually performed to block the saphenous nerve for 12-16 hours
postoperatively.
