Spinal Cord Stimulator Implant (Trial Procedure)

local anesthetic

Overview
Spinal cord stimulation (also called SCS) uses
electrical impulses to relieve chronic pain of the
back, arms and legs. It is believed that electrical
pulses prevent pain signals from being received by
the brain. SCS candidates include people who
suffer from neuropathic pain and for whom
conservative treatments have failed.


Trial Implantation
The injection site is anesthetized. One or more
insulated wire leads are inserted through an
epidural needle or through a small incision into the
space surrounding the spinal cord, called the
epidural space.


Find the Right Location
Electrodes at the end of the lead produce electrical
pulses that stimulate the nerves, blocking pain
signals. The patient gives feedback to help the
physician determine where to place the stimulators
to best block the patient’s pain. The leads are
connected to an external trial stimulator, which will
be used for approximately one week to determine if
SCS will help the patient.


Determine Effectiveness
If the patient and physician determine that the
amount of pain relief is acceptable, the system may
be permanently implanted. At the end of the trial
implantation, the leads are removed.
