![]() In the 2015 CT image, ossification of the posterior longitudinal ligament (OPLL) protruded to the spinal canal, exceeding 50% of the spinal canal diameter, and the canal diameter was narrowed from 13 mm to 4 mm compared with the 2005 image.įor the surgical spinal cord decompression, total laminectomy at the third to sixth cervical vertebrae was performed, and cervical spine fixation using lateral mass screw was performed. To decrease the chronic intractable cervical pain, he received paddle-type SCS (Medtronic, Minneapolis, MN, USA) insertion by a neurosurgeon at another hospital.Ĭomputed tomographic (CT) images acquired in 20. In 2005, the patient had chronic intractable cervical pain with a visual analog scale (VAS) score of 9 after a traffic accident, and he had symptomless ossification of posterior longitudinal ligament (OPLL) at the C2/3 and 3/4 area ( Figure 1). Moreover, at the time of admission, physical examination showed motor grade III/V in the arms allodynia and hyperalgesia were reported in the arms and legs, and there were obvious signs of cord compression, such as change in reflexes, numbness, and weakness in the arms and legs (American Spinal Association grade D). We are keen to report this case of metallosis and fibrosis at the site of SCS lead and suggest the possibility of metallic irritation of the dura mater following insertion of the SCS.Ī 46-year-old man presented at our pain clinic in 2015 with complaints of severe cervical pain, numbness in both arms, weakness in both legs, and gait disturbance. However, adverse effects caused by the SCS epidural electrode lead, resulting in metallic irritation of the dura, have not been reported yet. Although it has a high rate of success in treating various aforementioned pain disorders, complications following the insertion of spinal cord stimulators (SCS), such as hardware failures, spontaneous breakage, or late-onset cervical myelopathy, have been reported in the literature. Spinal cord stimulation is a well-established interventional procedure to achieve analgesia for various chronic pain conditions.
