In the years 1969-1986 operations were carried out in 1650 cases of lateral prolapse of the lumbar nucleus pulposus at one level, they accounted for 75% of patients operated on for symptomatic sciatic pains. The operations were done in lateral recumbent position. In 29% of cases it was necessary to extend the typical fenestration by reducing the size of one or two halves of the vertebral arches, and in 12% of cases full hemilaminectomy was done. The most frequent cause of fenestration extension was narrow yellow ligament and massive broad vertebral arches at the level of the prolapsed nucleus, as well as congenital or acquired narrowing of the lateral recess of the vertebral canal. In only 4% of cases the necessity of fenestration extension was due to displacement of the free fragments of the prolapsed nucleus far from the intervertebral space or their falling into the meningeal sac.
1969年至1986年期间，对1650例单节段腰椎髓核外侧突出患者进行了手术，这些患者占因坐骨神经痛症状接受手术治疗患者的75%。手术采用侧卧位进行。在29%的病例中，有必要通过减小一个或两个半椎弓的尺寸来扩大典型的开窗，在12%的病例中进行了全椎板切除术。扩大开窗最常见的原因是突出髓核水平的黄韧带狭窄和宽大的椎弓，以及椎管侧隐窝的先天性或后天性狭窄。仅4%的病例中，扩大开窗的必要性是由于突出髓核的游离碎片远离椎间隙移位或落入脑膜囊。
