内镜治疗伴有骨化的L5/S1极外侧间盘突出症1例报告
Endoscopic Treatment of Extreme Lateral Disc Herniation of L5/S1 with Ossification: A Case Report

背景：腰椎间盘突出症合并骨化是目前脊柱外科较为常见的疾病，是指在椎间盘退行性病变的基础上伴发椎间盘骨化、椎体后缘骨赘形成或黄韧带骨化等情况。患者多表现为下肢根性症状如疼痛麻木等。既往该疾病由于骨化部分无法切除、切除不彻底及易损伤硬膜等因素被视为微创脊柱内镜手术的禁忌症，故多采用开放式手术进行治疗。近年来，随着微创脊柱手术技术及器械的发展与完善，采用脊柱内镜治疗该疾病已愈发显示出其优势所在。
Lumbar intervertebral disc herniation combined with ossification is a relatively common disease in spine surgery at present, which refers to the ossification of the intervertebral disc, the formation of osteophytes at the posterior edge of the vertebral body, or the ossification of the ligamentum fla-vum on the basis of intervertebral disc degeneration. Patients often present with lower extremity radicular symptoms such as pain and numbness. In the past, the disease was regarded as a contra-indication to minimally invasive spinal endoscopic surgery due to factors such as unresectable ossi-fication, incomplete resection, and easy damage to the dura mater, so open surgery was often used for treatment. In recent years, with the development and improvement of minimally invasive spinal surgery techniques and instruments, the use of spinal endoscopy in the treatment of this disease has increasingly shown its advantages.
