Your wife had a stormy operative course. Hypersensitivity at the incision is not typical for hardware irritation but is typical for nerve injury. However taking out the instrumentation is a relatively easy surgery and may be helpful.

You mention AFGI for Tarlov cysts. I am unfamiliar with those initials. What procedure did she have performed for these cysts?

The lidocaine “challenge” test is designed to infiltrate the hardware/bone interface with numbing medication to see if the hardware is irritating the bone. The problem with this test is that the lidocaine rarely behaves the way we want it to and may not find its way along the bone. Also, other structures next to the hardware can also be numbed which gives a false positive (a test which indicates relief when the actual surgery will not provide relief).
