To date, no case studies specifically reporting an electrode dislodging from its lead wire have been reported. Here we describe a case involving an electrode shearing from the spinal cord stimulator lead, and lodging into the ligamentum flavum during implantation. In this case, an experienced board certified interventional pain management specialist was performing the implantation procedure of a magnetic resonance imaging (MRI) compatible spinal cord stimulator with MR conditional leads. ⋯ The decision was made to proceed with only one lead in place and the remainder of the procedure was completed uneventfully. The patient followed up two weeks later in clinic, and no adverse effect related to the dislodged electrode was reported. The indications and common complications associated with spinal cord stimulation are discussed, followed by factors to consider to help guide decision making in the event of a retained foreign body during a procedure.
