全内窥镜椎板间入路减压外侧隐窝狭窄
February 24th, 2023
全内窥镜脊柱手术的技术进步和经验的增加使这些手术能够以最小的切口、肌肉回缩和骨切除进行。
首先，使用 rongeur 去除软组织，主要是椎旁肌肉。用 5.4 毫米冲头去除黄韧带的表层，使降面完全暴露。要暴露升小面，请使用带侧向保护的 5.5 毫米椭圆形车针，并从其下端去除下小面内侧的骨头。
再次使用带有侧向保护的椭圆形车针来减薄上升面，以便通过 Kerrison 冲头实现完全去除。使用 Kerrison 冲头向外侧进一步去除骨头，然后使用冲头从中线向外侧切除黄韧带。确保黄韧带从内侧到外侧和颅骨到尾部去除，以完全观察外侧凹陷。
然后，使用 rongeur，小心地去除硬膜外脂肪组织，直到充分暴露于神经结构。使用解剖器向内侧动员神经根，以减轻其任何粘连。解决任何导致侧隐窝狭窄的椎间盘病变。
使用解剖器内侧化神经根或转动工作套筒的长边。通过切除一半的蒂和侧隐窝处的黄韧带来实现减压。术前矢状面和轴向磁共振图像显示右侧侧隐窝狭窄。
术后图像证实了这一发现的解决。

Executive Industry Relevance
Minimally invasive full-endoscopic interlaminar decompression for lateral recess stenosis addresses the need for tissue-sparing interventions in spinal surgery, reducing operational trauma and recovery time. This technique supports the transition from traditional laminectomy to advanced, less invasive procedures, aligning with biopharma priorities for improved patient outcomes and procedural efficiency. Its adoption can inform device development and translational research in neuro-orthopedic therapeutics.
Strategic Applications in Biopharma R&D
Early Discovery & Target Validation
- Enables precise anatomical targeting for device and therapeutic validation in spinal stenosis models.
- Supports mechanistic de-risking by isolating the impact of decompression on neural structures.
- Facilitates functional outcome assessment for translational device or biologic candidates.
Screening & Assay Development
- Provides a reproducible surgical workflow for preclinical evaluation of neuroprotective agents or biomaterials.
- Standardizes exposure and decompression endpoints for comparative studies.
- Enables quantitative imaging and functional readouts post-decompression.
Translational & Preclinical Research
- Aligns with disease-relevant models for lateral recess stenosis and nerve root compression.
- Supports continuity from surgical intervention to biomarker and functional outcome assessment.
- Reduces confounding variables by minimizing tissue disruption and post-surgical complications.
Pipeline & Workflow Integration
This full-endoscopic decompression technique integrates into the discovery-to-preclinical continuum for neuro-orthopedic device and therapeutic development.
- Discovery Biology: Enables hypothesis testing on neural decompression and tissue response.
- Screening: Provides standardized, reproducible endpoints for device or compound evaluation.
- Analytics: Supports quantitative imaging and functional assessment of decompression efficacy.
