N2 - With a growing number of patients treated with deep brain stimulation (DBS) operations for both hardware-related complications and routine replacements of impulse generators will be performed more frequently. Failure of DBS systems have to be analyzed thoroughly as this thwarts the enormous efforts required for proper electrode implantation and operative revisions increase the morbidity associated with DBS. A female patient implanted with DBS electrodes for advanced Parkinson's disease presented with straining of the right extension lead and deteriorating gait because of electrode migration. This was due to a malpositioned set screw connector adapting the electrode lead to the extension wire which had been placed below the mastoid process. Following surgical revision with implantation of a new electrode into the STN, electrode dislocation recurred requiring another surgical revision. This was due to renewed connector migration from its parietal position into the cervical region. Straining of extension leads should be recognized as a warning sign for (imminent) electrode dislocation or lead fracture. This may just be the case with connectors located below the mastoid process or in the cervical region, a risk which appears to be increased further with reduced-length extensions. Renewed dislocation of revised extensions may be prevented by securing the position of the connector (e.g. with manipulates).
