Overview

Spinal cord stimulator (SCS) implantation is a minimally invasive neurosurgical procedure for treating chronic pain that hasn't gotten better with drugs, physical therapy, or other surgeries. The device has thin electrical leads close to the spinal cord and a small pulse generator placed under the skin, usually in the abdomen or buttocks. The stimulator sends weak electrical signals to the spinal cord, which alter pain signals before they reach the brain. Spinal cord stimulation doesn't fix the cause of pain, but it does make the pain feel much less intense. It is often used to treat chronic neuropathic pain, failed back surgery syndrome, and complex regional pain syndrome.

Why It's Done
When conservative treatments don't work, and chronic pain keeps coming back, a spinal cord stimulator is put in. Long-term use of opioids or repeated surgeries may not give enough relief and may cause side effects. The stimulator reduces pain and improves function by altering how pain signals reach the brain. Pain specialists and neurosurgeons usually recommend it after careful consideration, especially when quality of life is severely affected.

What to Expect
Patients usually go through a trial stimulation phase before getting a permanent implant. The external stimulator is tested for several days to assess its effectiveness, and temporary leads are placed under local anaesthesia. If the pain improves significantly, the implant will be placed permanently. General or local anaesthesia with sedation may be used during the permanent procedure. Under X-ray guidance, leads are put into the epidural space near the spinal cord through a needle. The pulse generator is put under the skin and linked to the leads. After surgery, the device is programmed to deliver the appropriate amount of stimulation. Patients learn how to use an external remote to control the device. Follow-up visits are planned to change the stimulation settings for the best pain relief.

Recovery & Outlook
Recovery usually happens faster than major spine surgery, but there may be some mild pain at the incision sites. Patients should avoid lifting heavy objects or moving quickly for a few weeks. Many people feel a lot less pain for a long time, which makes it easier for them to move around and lessens their need for painkillers. Long-term results depend on the condition that caused the problem and how well the person follows up on their care. Regular checks ensure the device works properly and continues relieving pain.
