Abstract：
UNASSIGNED: Extraforaminal stenosis in L5-S1, or far-out syndrome (FOS), is defined as L5 nerve compression by the transverse process (TP) of the L5 and the ala of the sacrum and disc bulging with/without osteophytes and/or the thickened lumbosacral and extraforaminal ligament. This study aims to describe the unilateral biportal endoscopic decompression technique of the extraforaminal stenosis at L5-S1 or far out syndrome and evaluate its clinical results with a literature review.
UNASSIGNED: A 44-year-old male presented with severe right sharp shooting pain in the buttock, thigh, leg, foot, and/or toes with numbness in the foot and toes (Visual Analog Scale [VAS] 8/10) for six months with an Oswestry disability index (ODI) score of 70%. Her pain aggravated when bending forward and performing daily routine activities. He also complained of exaggeration of pain in daily regular activities. On physical examination, power in the right lower limbs was 5/5 as per the Medical Research Council (MRC) grading, and deep tendon reflexes were normal. Pre-operative X-ray and CT scan showed no instability or calcified disc osteophyte, and magnetic resonance imaging showed extraforaminal stenosis due to disc herniation at L5-S1 in Figure 1. We performed UBE-L5-S1extraforaminal discectomy surgery to resolve his symptoms. The operative time was 68 min; blood loss was 30 mL. After surgery, the patient was followed up at one week, six weeks, three months, six months, 12 months, and two years. The pain and tingling sensation in the legs improved at the 1-week follow-up, with a VAS score of 0/10 and an ODI score of 10% at the 2-year follow-up. Patient satisfaction was surveyed using Macnab\'s criteria at the final follow-up visit of 2 years and was found to be excellent. Post-operative imaging showed a good extraforaminal decompression at L5-S.
UNASSIGNED: Unilateral biportal endoscopy technique has brought a paradigm shift in the treatment of spinal pathologies and has served as another treatment option for the past two decades. The UBE decompression technique for extraforaminal stenosis at L5-S1 has the advantages of minimally invasive spine surgery; it is a safe and effective treatment option for treating extraforaminal stenosis at L5-S1.

摘要：
■L5-S1椎间孔狭窄或远处综合征（FOS），定义为L5神经受到L5的横突（TP）以及the骨和椎间盘凸出的，有/没有骨赘和/或增厚的腰骶骨和椎间孔外韧带的压迫。本研究旨在描述L5-S1或远处综合征的椎间孔外狭窄的单侧双孔内镜减压技术，并通过文献综述评估其临床结果。
■一名44岁男性臀部出现严重的右尖锐射击疼痛，大腿,腿,脚,和/或脚趾麻木（视觉模拟量表[VAS]8/10）持续六个月，Oswestry残疾指数（ODI）评分为70％。向前弯曲并进行日常活动时，她的疼痛加剧。他还抱怨在日常活动中夸大疼痛。在体检时，根据医学研究理事会（MRC）分级，右下肢的力量为5/5，深肌腱反射正常。术前X线和CT扫描显示椎间盘骨赘不稳定或钙化，和磁共振成像显示在图1中的L5-S1椎间盘突出导致的椎间孔外狭窄。我们进行了UBE-L5-S1椎间孔外椎间盘切除术以解决他的症状。手术时间68min,术中出血量30mL。手术后,病人在一周后接受了随访，六周,三个月,六个月,12个月,还有两年.在1周的随访中，腿部的疼痛和刺痛感得到改善，在2年的随访中，VAS评分为0/10，ODI评分为10％。在2年的最后一次随访访视时，使用Macnab标准调查患者满意度，结果为优秀。术后影像学显示L5-S处椎间孔外减压良好。
■单侧双入口内窥镜检查技术带来了脊柱病变治疗的范式转变，并在过去二十年中成为另一种治疗选择。UBE减压技术治疗L5-S1椎间孔外狭窄具有微创脊柱手术的优点，是治疗L5-S1椎间孔外狭窄安全有效的治疗选择。
