Development of a syrinx several years post spinal cord trauma is a well-known entity and described in a number of scientific communications. Each one describes the few cases encountered with the clinical presentations; many report results of myelography with positive or negative contrast media, operative procedures, and eventual outcome as well as discussions of autopsy material. It is believed by many investigators and clinicians that surgical intervention frequently stops the progression of the syrinx and sometimes even reverses the symptomatology. Early exact diagnosis is thus paramount. Electromyography if used judiciously, may be an important adjunct to proper diagnosis and prognosis. In a patient with previous spinal cord trauma, frequently even post-surgical procedures, the interpretation is often difficult. This paper discusses the electrodiagnostic findings in three patients with post-traumatic syrinx and compares them with electrodiagnostic changes observed in a spinal cord injury patient with increased symptomatology due to other causes and two patients with non-traumatic cervical syringomyelia.
脊髓损伤数年之后出现空洞是一个广为人知的情况，并且在许多科学文献中都有描述。每一篇文献都描述了所遇到的少数病例及其临床表现；许多文献报告了使用阳性或阴性造影剂的脊髓造影结果、手术过程、最终结局，以及尸检材料的讨论。许多研究者和临床医生认为，手术干预常常能阻止空洞的进展，有时甚至能使症状逆转。因此，早期准确诊断至关重要。如果明智地使用肌电图，它可能是正确诊断和预后的重要辅助手段。在既往有脊髓损伤的患者中，甚至在术后，其解读往往也很困难。本文讨论了3例创伤后空洞患者的电诊断结果，并将其与1例因其他原因导致症状加重的脊髓损伤患者以及2例非创伤性颈段脊髓空洞症患者观察到的电诊断变化进行了比较。
