To introduce the concept of 'nerve root as the core' and to investigate the surgical procedure and curative effect of percutaneous translaminar endoscopic discectomy (PTED) surgery in the treatment of different types of lumbar disc herniation (LDH).
This retrospective study analysed the clinical data from patients with LDH that underwent single-segment PTED surgery. They were divided into three groups based on LDH location: central canal zone group, lateral recess zone group and foraminal/far lateral zone group. Different working cannula placement methods were used for the different types of LDH. All patients were followed for at least 12 months. Clinical and follow-up data were compared between the three groups.
A total of 130 patients were enrolled in the study: 44 (33.8%) in the central canal zone group, 72 (55.4%) in the lateral recess zone group and 14 (10.8%) in the foraminal/far lateral zone group. All three groups of patients achieved good postoperative results. The improvements in leg pain and disability were most marked in the first postoperative month in all three groups.
PTED achieved adequate decompression for different types of LDH. The concept of 'nerve root as the core' facilitated the accurate placement of the working cannula.
介绍“以神经根为核心”的概念，并探讨经皮经椎间孔内镜椎间盘切除术（PTED）治疗不同类型腰椎间盘突出症（LDH）的手术步骤和疗效。
本回顾性研究分析了接受单节段 PTED 手术的 LDH 患者的临床资料。根据 LDH 位置将患者分为中央管区组、侧隐窝区组和椎间孔/远外侧区组。不同类型的 LDH 采用不同的工作套管放置方法。所有患者均至少随访 12 个月。比较三组之间的临床和随访资料。
共纳入 130 例患者：中央管区组 44 例（33.8%），侧隐窝区组 72 例（55.4%），椎间孔/远外侧区组 14 例（10.8%）。三组患者术后均取得良好效果。三组患者术后 1 个月内腿部疼痛和残疾均有明显改善。
PTED 对不同类型的 LDH 均可达到充分减压。“神经根为核心”的概念有助于工作套管的准确定位。
