Spinal Cord Stimulator (SCS) implantation is a modern neuromodulation technique used for the treatment of chronic pain that is resistant to pharmacological therapy. The device delivers electrical impulses to the spinal cord, interrupting the transmission of pain signals to the brain and significantly improving the patient’s quality of life.
Indications for Spinal Cord Stimulator implantation
Chronic pain conditions:
- Neuropathic pain (after trauma or surgical interventions).
- Post-laminectomy syndrome (persistent pain after spinal surgery).
Vascular disorders:
- Complex Regional Pain Syndrome (CRPS).
- Ischemic pain in severe peripheral arterial disease.
Nervous system disorders:
- Diabetic neuropathy.
- Nerve root injuries (radiculopathy).
Other conditions:
- Phantom limb pain after amputation.
- Refractory angina pectoris.
- Spinal cord injuries with neurological complications.
Contraindications
Absolute:
- Active infection at the planned implantation site.
- Severe, uncontrolled psychiatric disorders.
- Intolerance to implantable materials.
Relative:
- Systemic infections.
- Uncontrolled coagulopathy.
- Pregnancy.
Components of a Spinal Cord Stimulation system
Leads (electrodes):
- Placed epidurally near the spinal cord.
- Deliver electrical impulses to neural structures.
Implantable Pulse Generator (IPG):
- Controls the amplitude, frequency, and duration of electrical stimulation.
- Implanted subcutaneously, most commonly in the gluteal or abdominal region.
Patient controller: allows the patient to adjust stimulation parameters within predefined limits.
Preoperative preparation
- Clinical assessment: comprehensive evaluation by a neurologist and neurosurgeon.
- Diagnostics: MRI and CT of the spine, electromyography (EMG), nerve conduction studies, and psychological assessment.
- Trial stimulation period: temporary lead placement to evaluate the effectiveness of spinal cord stimulation before permanent implantation.
Surgical procedure
- Anesthesia. Local or general anesthesia depending on procedural complexity.
- Lead placement. Through a small incision, electrodes are introduced into the epidural space under fluoroscopic guidance.
- Implantation of the pulse generator. The IPG is placed subcutaneously and connected to the leads via extension cables.
- System programming. Post-implantation adjustment of stimulation parameters to achieve optimal pain relief.
Postoperative period
- Medication support: analgesics for postoperative discomfort and antibiotics for infection prophylaxis.
- Rehabilitation: gradual return to daily activities with temporary restrictions on heavy lifting and sudden movements.
- Stimulation optimization: regular follow-up visits for reprogramming of the device.
- Clinical follow-up: scheduled examinations by a neurologist or neurosurgeon.
In Belarus, spinal cord stimulator implantation is performed in specialized neurosurgical centers using advanced equipment and modern neuromodulation technologies. Experienced specialists provide an individualized approach at all stages, from diagnostic evaluation to postoperative rehabilitation. High standards of medical care combined with cost-effective treatment options make Belarus an attractive destination for international patients seeking advanced pain management solutions.
