Missed broken electrode of the spinal cord stumulator: A case report
Department of Anesthesiology and Pain medicine, Seoul National University Bundang Hospital
1. Introduction
Complications of Spinal cord stimulator (SCS) have been reported before, with the two most common being infection and migration or breakage. SCS breakage usually occurs at the anchor site. In this case report, the authors describe the breakage at the tip of the electrode of SCS, which is a rare complication. High mobility of the cervical vertebrae increases the fracture rate of lead placed in the cervical vertebrae.
2. Case report
A 30-year-old man visited the pain center to remove the inserted SCS due to insufficient effectiveness.. Nine year ago, the patient received SCS with the diagnosis of CRPS, which was developed after intravenous fluid infusion in the military medical office. This patients had used SCS for 7 years without complications. For last 2 years, this patients has not used SCS due to the reduced effect and has decided to remove it. . He has been taking fentanyl patches, amitriptyline, and IR codon prescriptions at a local medical center for pain control. The SCS was removed without resistance when the electrode was removed.
Residual lead was observed at C2 level in the X-ray image performed after operation. And the review of the pre-operative X-ray image revealed that the electrode was already broken before removal. The patient was notified that the SCS tip remained and explained that surgical removal was possible if desired. But the patient was discharged because he did not want surgical removal.
3. Conclusion
Due to the high mobility of the cervical spine, the electrode of SCS can be broken. A careful review of the pre-operative X-ray image can ensure the completeness of the SCS electrode.
