摘要

引言/目的:脊柱旁肌肉是根性神经病电诊断测试的重要组成部分。在颈椎区域,颈椎脊柱旁绘图方案假定肌电图(EMG)针能准确刺入颈椎多裂肌。然而,有关在该肌肉中放置针的准确性的信息却很少。本研究探讨了这一方案在尸体多裂肌取样的准确性:一位经验丰富的肌电图专家将针头指向 19 具防腐尸体的 C5、C7 和 T2 棘突处的多裂肌,并注入彩色染料。另一名检查员分别解剖尸体,注意染料是否位于正确位置,其轨迹是否接近任何神经、动脉或关节 "危险区":结果:染色剂100%进入多裂肌,并在79%、73%和79%的C5、C7和T2插入部位命中预定的骨性目标。没有发现插入危险区域:讨论:研究结果表明,临床方案中提出的 EMG 穿刺针置放准确性不高。这种方法的临床实用性需要更多的工作,包括建立规范、灵敏度、特异性和临床影响。

Anatomical validation of needle placement for cervical paraspinal mapping of the multifidus.

Introduction/aims: The paraspinal muscles are an important component of electrodiagnostic testing for radiculopathy. In the cervical region, a protocol for cervical paraspinal mapping assumes accurate placement of the electromyography (EMG) needle into the cervical multifidus. However, there is scant information regarding the accuracy of needle placement in that muscle. This study examines the accuracy of this protocol in sampling the intended multifidus muscle of cadavers.

Methods: An experienced electromyographer directed needles to multifidus at C5, C7, and T2 spinous processes of 19 embalmed cadavers, and injected color dyes. Separately another examiner dissected the cadavers, noting whether the dye was in the correct location and whether its trajectory approached any "danger zones" of nerve, artery, or joint.

Results: The dye was in the multifidus muscle 100% of the time and hit the intended bony target in 79%, 73%, and 79% of C5, C7, and T2 insertions. No insertion was found in a danger zone.

Discussion: The results indicate modest accuracy for EMG needle placement as proposed in the clinical protocol. Clinical utility of this method requires more work including the establishment of norms, sensitivities, specificities, and clinical impact.

期刊介绍: Muscle & Nerve is an international and interdisciplinary publication of original contributions, in both health and disease, concerning studies of the muscle, the neuromuscular junction, the peripheral motor, sensory and autonomic neurons, and the central nervous system where the behavior of the peripheral nervous system is clarified. Appearing monthly, Muscle & Nerve publishes clinical studies and clinically relevant research reports in the fields of anatomy, biochemistry, cell biology, electrophysiology and electrodiagnosis, epidemiology, genetics, immunology, pathology, pharmacology, physiology, toxicology, and virology. The Journal welcomes articles and reports on basic clinical electrophysiology and electrodiagnosis. We expedite some papers dealing with timely topics to keep up with the fast-moving pace of science, based on the referees'' recommendation.
