What to expect from the spinal stimulator implant
Spinal cord stimulation surgery is typically performed in two phases: a trial phase and an implantation phase. Each phase has a different treatment objective and process.
Before completing the permanent spinal implant, your doctor may recommend a trial stimulation period to ensure SCS is an effective treatment option for your specific pain condition. During this trial period, which typically lasts five to seven days, a temporary electrode is inserted through a needle into the epidural space in the spine. This electrode is connected to an external stimulator that you can control.
If the trial is successful and you experience significant pain relief, the next step is to select the appropriate spinal stimulator device. Your doctor will choose the device model that best meets your specific needs and preferences.
On the day of the implantation surgery, you'll receive either general anesthesia or local anesthesia with sedation. Your surgeon will make an incision over the area in the lower back where the electrode leads will be implanted. Next, your surgeon will remove the temporary electrode leads and then insert the permanent leads through a needle or a small incision into the epidural space near the spinal cord. Your surgeon will make another small incision, typically in your buttock, chest, or abdomen, and implant the pulse generator (also known as the stimulator or battery) before connecting the leads to the pulse generator.
After the leads and pulse generator are implanted, your doctor will test them to ensure they are in the right position. You may be awake during this part of the surgery to provide feedback on stimulation levels. Once the proper settings are confirmed, your surgeon will secure the leads and close the incision with sutures or staples.
Most patients can go home on the same day as their implantation procedure. Your doctor may require you to stay overnight if additional observation is needed.
