经皮内窥镜腰椎椎间盘切除术（PED）是一项相对较新的技术，由于其相对较小的侵入性而变得越来越普遍。然而，一个可能的严重并发症是当内窥镜的套管通过椎间孔插入神经管时，神经损伤。最近建立了一种扩大椎间孔的技术，称为椎间孔成形术，用于将套管安全地插入神经管的适当位置。方法在局麻下对15例患者行椎间孔成形术。通过术前和术后的计算机断层扫描，评估椎间孔的形态学变化。回顾手术相关并发症。结果男性13例，女性2例，年龄21 ~ 86岁，平均47.1岁。椎间盘水平为L4-L5 13例，L3-L4 1例，L5-S1 1例。在50%的病例中，平均椎间孔面积从术前的58.6 mm(2)显著增加到术后的88.4 mm (2)
Background Percutaneous endoscopic diskectomy (PED) for the lumbar spine is a relatively new technique that is becoming more common due to its relatively less invasive nature. However, one possible serious complication is an exiting nerve injury when the cannula of the endoscope is inserted into the neural canal through the intervertebral foramen. A technique to enlarge the intervertebral foramen, called foraminoplasty, was recently established to insert the cannula safely into an appropriate position in the neural canal.Methods In this study we performed foraminoplasty during PED under local anesthesia on 15 patients. Using computed tomography scans before and after surgery, the morphometric changes of the intervertebral foramen were evaluated. Surgery-related complications were reviewed.Results There were 13 men and 2 women, 21 to 86 years of age (mean: 47.1 years). Disk levels were 13 cases at L4-L5, one case at L3-L4, and one case at L5-S1. In 50% of the cases, the mean foraminal area significantly increased from 58.6 mm (2) before surgery to 88.4 mm (2) after surgery ( p
