Anterior odontoid screw fixation technique for specific types of odontoid fracture has been proven to be an effective, yet challenging procedure because of threatened damage to the structures in the vicinity. There are few articles suggesting the role of percutaneous and endoscopic technique as an alternative approach to the standard microscopic way. This is the first cadaveric study using existing "EASY GO" endoscopic system-assisted odontoid screw placement.
This was a cadaveric study.
The objective of the study is to use the endoscope as a safer minimally invasive approach than the standard microscopic anterior approach to odontoid.
This is a pilot study on 10 fresh-frozen formalin-fixed adult human cadavers. The cadaver was positioned in a way to simulate reduced odontoid fracture. Tubular dilators were used to dock at C2-3 disk space after identifying the landmarks through the microscopic method. The EASY GO endoscopic system was then introduced, and a handheld drill was used to mark the entry point and pass the K-wire through the planned trajectory.
No vascular or adjacent vital structures' injury was observed in any of the cadavers. The initial difficulty in attaining the alignment was overcome by the appropriate positioning of the scope.
Endoscopic-assisted technique for odontoid screw fixation shall provide a minimally invasive, safe, and easy surgery.
对于特定类型的齿状突骨折，前路齿状突螺钉固定技术已被证明是一种有效的方法，但由于周围结构有受损风险，该手术具有挑战性。很少有文章提出经皮和内镜技术可作为标准显微镜手术方法的替代方案。这是第一项使用现有的“EASY GO”内镜系统辅助进行齿状突螺钉置入的尸体研究。
这是一项尸体研究。
本研究的目的是使用内镜作为一种比标准显微镜下前路齿状突手术更安全的微创方法。
这是一项针对10具新鲜冷冻、经福尔马林固定的成年人体尸体的初步研究。将尸体摆放成模拟齿状突骨折复位的姿势。通过显微镜方法确定标志点后，使用管状扩张器在C2-3椎间盘间隙对接。然后引入“EASY GO”内镜系统，使用手持钻标记进针点并使克氏针穿过预定轨迹。
在任何一具尸体中均未观察到血管或相邻重要结构损伤。通过适当调整内镜位置克服了最初在实现对线方面遇到的困难。
内镜辅助齿状突螺钉固定技术应能提供一种微创、安全且简便的手术。
