The purpose of this study was to develop a minimally invasive approach to equine cervical articular facet joints for application of an ND:YAG LASER and to evaluate the effects of the laser fiber on the surrounding tissue. Under general anesthesia, an ND:YAG LASER was used to apply 2000 J of energy to 5 cervical articular facet joints in 3 horses (15 joints total). Horses were euthanized and the cervical facets and spinal cords were examined grossly and histologically. Gross pathology of the articular facets revealed evidence of articular cartilage charring and diffuse roughening of the surface. Histopathology confirmed coagulative necrosis. This novel technique allowed access to the cervical articular facet joints with the ND:YAG LASER and has the potential to allow performance of a minimally invasive facilitated ankylosis procedure. Further validation in sedated, standing horses is required to establish safety and efficacy of this technique.
本研究的目的是开发一种用于马颈椎关节突关节的微创方法，以便应用掺钕钇铝石榴石（ND:YAG）激光，并评估激光光纤对周围组织的影响。在全身麻醉下，使用ND:YAG激光对3匹马的5个颈椎关节突关节施加2000焦耳能量（共15个关节）。对马实施安乐死后，对颈椎关节突和脊髓进行大体和组织学检查。关节突的大体病理学显示有关节软骨炭化和表面弥漫性粗糙的迹象。组织病理学证实为凝固性坏死。这种新技术允许使用ND:YAG激光进入颈椎关节突关节，并有可能进行微创促进关节融合手术。需要在镇静站立的马匹中进行进一步验证，以确定该技术的安全性和有效性。
