Sixteen patients were operated on for lumbar pain and pain radiating into the sciatic nerve distribution. In all 16, when the anulus fibrosus was incised, soft, gray disc material extruded under pressure like toothpaste being squeezed from a tube. This syndrome of myxomatous degeneration is a distinct entity, different from classical fibrotic disc degeneration or herniated nucleus pulposus. Surgical removal associated with partial facetectomy produced excellent results. The concept of incompetence of the anulus fibrosis is discussed.
16名患者因腰痛及放射至坐骨神经分布区域的疼痛接受了手术。在所有16例患者中，当纤维环被切开时，柔软、灰色的椎间盘物质在压力下像牙膏从管中被挤出一样挤出。这种黏液瘤样变性综合征是一种独特的实体，不同于经典的纤维化椎间盘退变或髓核突出。与部分小关节切除术相关的手术切除产生了极佳的效果。文中讨论了纤维环功能不全的概念。
