Abstract

BACKGROUND CONTEXT

Lumbar foraminal stenosis is a condition in which a nerve root or spinal nerve is entrapped in a narrow lumbar foramen in degenerative lumbar spinal disorders. Several different techniques for this problem had been described, including foraminotomy, facetectomy, partial pediculectomy, fusion, and distraction instrumentation. Nowadays full-endoscopic lumbar surgery was able to decompress lumbar foramen, and prevente from proceeding to a more aggressive procedure.

PURPOSE

To describe the full-endoscopic lumbar foraminoplasty with midline skin incision (FEFM) and lateral recess decompression procedure and to report its clinical outcomes at the 1-year follow-up.

STUDY DESIGN/SETTING

This is a retrospective study revealed the technique of full-endoscopic midline lumbar foraminoplasty and clinical outcomes of 30 patients up to 1 year.

PATIENT SAMPLE

The 30 consecutive patients between August 2021 and August 2022 with lumbar foraminal and/or lateral recess stenosis who underwent FEFM procedure were retrospectively reviewed.

OUTCOME MEASURES

Clinical outcomes were evaluated with visual analog scale (VAS) of back and leg pain and Oswestry Disability Index (ODI) up to 1 year postoperatively. The complications and recurrence rate were also recorded

METHODS

The detailed of full-endoscopic lumbar midline foraminoplasty was step-by-step demonstrated.

RESULTS

A total of 30 cases were included (L3–L4: 6 cases (20%), L4–L5: 23 (76.6%), L5–S1: 22 cases (73.3%). VAS was collected at preoperative, postoperative day1, 3 month, 6 month and 1 year were 9.16,1.7,1.36,1.3,1.43 and respectively. The ODI were collected at preoperative, postoperative 1month, 3 month, 6 month and 1 year were 46.63,11.5,10.66,10.46 respectively (P < 0.05). The mean operation time was 88.7 minutes (45-152 minutes). The length of hospital stay was 1.21 (1-3 days). No immediate complication was identified No patient had recurrence of symptoms that required revision surgery.

CONCLUSIONS

FEMF is an effective procedure for the treatment of foraminal and/or lateral recess stenosis. Bilateral foraminal and lateral recess stenosis were able to be decompressed from single entry point.

P44。全内窥镜中线椎间孔成形术：治疗腰椎椎间孔狭窄的另一种方法

背景：腰椎椎间孔狭窄是指退行性腰椎疾病患者的神经根或脊神经被困在狭窄的腰椎孔内。已有几种不同的治疗方法，包括椎间孔切开术、椎面切开术、部分椎弓根切除术、融合术和撑开内固定术。如今，全内窥镜腰椎手术能够减压腰椎孔，并防止进行更有侵略性的手术。目的介绍经中线皮肤切口（FEFM）和外侧隐窝减压的全内镜腰椎椎间孔成形术，并报告其1年随访的临床结果。研究设计/背景：这是一项回顾性研究，揭示了全内窥镜腰椎椎间孔成形术技术和30例患者长达1年的临床结果。患者样本：回顾性分析了2021年8月至2022年8月期间连续30例腰椎椎间孔和/或侧隐窝狭窄患者接受FEFM手术。采用视觉模拟量表（VAS）和Oswestry残疾指数（ODI）评估术后1年的背部和腿部疼痛的临床结果。方法详细介绍全内窥镜下腰椎椎间孔成形术的操作步骤。结果共纳入30例，其中L3-L4: 6例（20%），L4-L5: 23例（76.6%），L5-S1: 22例（73.3%）。术前、术后第1天、第3个月、第6个月和第1年VAS分别为9.16、1.7、1.36、1.3、1.43和1.43。术前、术后1个月、3个月、6个月、1年ODI分别为46.63、11.5、10.66、10.46 (P <；0.05)。平均手术时间88.7分钟（45 ~ 152分钟）。住院时间1.21天（1 ~ 3天）。没有发现立即并发症，没有患者出现需要翻修手术的症状复发。结论sfemf是治疗椎间孔和/或外侧隐窝狭窄的有效方法。双侧椎间孔和外侧隐窝狭窄能够从单一入路点减压。FDA器械/药物状态本摘要不讨论或包括任何适用的器械或药物。
