Abstract: This article reviews the application and progress of minimally invasive techniques in the treatment of cervical spondylotic radiculopathy. Through a systematic review of relevant literature, it compares and analyzes the processes, operations, advantages, and disadvantages of various minimally invasive techniques, including unilateral dual-channel endoscopy, foraminoscopy, microendoscopy, radiofrequency, and collagenase. Currently, conservative treatment remains the primary approach for clinical management of cervical spondylotic radiculopathy; however, minimally invasive surgery has become an important option due to its advantages. Among these, the Key-hole technique performed under unilateral dual-channel endoscopy shows promising clinical prospects due to its gentle learning curve, short operative time, lower costs, and the ability to utilize existing instruments.

摘要： 本文综述了微创技术治疗神经根型颈椎病的应用与进展。通过系统回顾相关文献，对比分析单侧双通道脊柱内镜、椎间孔镜、显微内窥镜、射频及胶原酶等微创技术的进程、操作及优缺点。目前，神经根型颈椎病的临床治疗仍以保守治疗为主，但微创手术因其优势已成为重要选择。其中，单侧双通道内镜下的Key-hole技术因学习曲线平缓、手术时间短、成本较低且可利用现有器械，展现出广阔的临床应用前景。
