It is a method of affecting weak electrical impulses on the neural structures of the spinal cord to block various neurogenic pathological conditions. The effect is achieved by means of electrical pulses, which are delivered by electrodes implanted in the epidural space.
Indications for neurostimulation: syndrome of the "operated spine" or post-aminectomy syndrome, complex regional pain syndrome (CRPS) of types I and II, painful radiculopathy (with or without pain in the lower back), critical ischemia of the lower extremities, accompanied by severe pain, pain due to spine trauma , stenosis of the spinal canal and impaired function of the pelvic organs.
Neurostimulation is carried out with the help of a small device-generator of electrical impulses, a special electrode that is implanted in the region of the spinal cord above the dura mater and the connecting microwire. The entire system is not visible, as it is under the skin and does not constrain the patient's movements.
Based on medical indications, the patient is implanted with a system for chronic neurostimulation. Under X-ray control of the needle or a small incision of soft tissues, a multi-contact electrode is implanted. It is located above the membranes of the spinal cord, without touching the brain itself. The doctor determines the required electrostimulation parameters and the accuracy of the electrode location. The electrode is connected to the subcutaneous programmable pulse generator using a thin extension cable. The procedure of implantation of the neurostimulator does not lead to damage to the spine and spinal cord, to a violation of nerve conduction in the spinal cord. The operation is performed under local anesthesia.
When the electrode is implanted, the period of trial stimulation can last several days. At this time, the correct stimulation mode is selected, changing the parameters of the voltage of the pulse generator and the duration of continuous operation.
