The observation of the human spinal canal and its contents using newly developed ultrathin fiberoptic myeloscope. The purpose of this study was observed directly the spinal cord, some of the nerves or blood constituents of cauda equina and epidural space with fiberoptic ultrathin myeloscope.Our myelofiberscope has been used successfully in visualizing the spinal cord from cauda equina to cisterna magna in 98 adults. It is very flexible with insertion tube of outer diameter 0.75mm and with a working length of 120cm. This instruments has 4000 quartzfiber optic image guide and 35 light guides. The lumbar subarachnoid space was identified by the hanging drop method with an 18 Gauge Tuohy needle under local anesthesia. We could see the many spinal nerve roots with its accompanying blood vessels, spinal cord tumor, adhesive arachnoiditis. This procedure would be useful for establishing the differential diagnosis of tumor, spinal canal stenosis or neurovascular compression.

纤维脊髓镜对人体椎管及其内容物的观察。本文应用纤维脊髓镜直接观察脊髓、马尾神经及硬膜外腔的某些神经或血液成分，并成功地观察了98例成人马尾至枕大池的脊髓。其非常灵活，插入管外径为0.75 mm，工作长度为120 cm。该仪器有4000个石英光纤图像引导和35个光导。在局部麻醉下使用18号Tuohy针通过悬滴法确定腰椎蛛网膜下腔。可见多根脊神经根及其伴行的血管、脊髓肿瘤、粘连性蛛网膜炎。该方法有助于肿瘤、椎管狭窄或神经血管压迫的鉴别诊断。
