Abstract

Current shunting is a potential cause of false negative threshold values whenever triggered EMG is utilized. We present a case where we stimulated percutaneously placed pedicle screws both with and without an insulated dilator to show the potential difference in threshold values. Our findings suggest that the risk of current shunting associated false negatives when stimulating pedicle screws placed via minimally invasive percutaneous approaches may be higher unless insulated dilators are utilized.

简短报告：经皮置钉时带和不带绝缘扩张器的椎弓根螺钉刺激值。

当使用触发肌电图时，电流分流是假阴性阈值的潜在原因。我们提出了一个病例，我们刺激经皮放置椎弓根螺钉，无论有无绝缘扩张器，以显示阈值的潜在差异。我们的研究结果表明，除非使用绝缘扩张器，否则经微创经皮入路置入刺激椎弓根螺钉时，电流分流相关假阴性的风险可能更高。

期刊介绍： The Neurodiagnostic Journal is the official journal of ASET - The Neurodiagnostic Society. It serves as an educational resource for Neurodiagnostic professionals, a vehicle for introducing new techniques and innovative technologies in the field, patient safety and advocacy, and an avenue for sharing best practices within the Neurodiagnostic Technology profession. The journal features original articles about electroencephalography (EEG), evoked potentials (EP), intraoperative neuromonitoring (IONM), nerve conduction (NC), polysomnography (PSG), autonomic testing, and long-term monitoring (LTM) in the intensive care (ICU) and epilepsy monitoring units (EMU). Subject matter also includes education, training, lab management, legislative and licensure needs, guidelines for standards of care, and the impact of our profession in healthcare and society. The journal seeks to foster ideas, commentary, and news from technologists, physicians, clinicians, managers/leaders, and professional organizations, and to introduce trends and the latest developments in the field of neurodiagnostics. Media reviews, case studies, ASET Annual Conference proceedings, review articles, and quizzes for ASET-CEUs are also published in The Neurodiagnostic Journal.
