ryggmärgsstimulator

A ryggmärgsstimulator, also known as a spinal cord stimulator, is a medical device used to treat chronic pain. It works by sending low levels of electrical pulses to the spinal cord. These pulses interfere with pain signals traveling to the brain, effectively masking the sensation of pain. The device typically consists of a pulse generator, similar to a pacemaker, and a lead wire that is implanted near the spinal cord.

The implantation procedure is usually minimally invasive and performed under local anesthesia or sedation. A surgeon carefully inserts the lead wire into the epidural space, the area surrounding the spinal cord. The pulse generator is then placed under the skin, often in the abdomen or buttock. The patient can then control the intensity and pattern of the electrical pulses using a remote control.

Ryggmärgsstimulatorer are primarily used for conditions like failed back surgery syndrome, complex regional pain syndrome (CRPS), and peripheral neuropathy. They are considered when conservative treatments such as medication, physical therapy, and injections have not provided adequate pain relief. While not a cure for the underlying condition, spinal cord stimulation can significantly improve quality of life by reducing pain and the need for pain medication. Potential risks include infection, lead migration, and hardware malfunction.
