At the beginning of clinical application, CBT technique was mainly used for lumbar degenerative diseases in Elderly Patients, and single or double segments of lower lumbar vertebrae accounted for the majority. With the technical proficiency and equipment improvement, the types of diseases continue to expand, and CBT technique can be used in conjunction with traditional pedicle screw technology, which plays an important role in the revision of adjacent segment disease and fixation in lumbar vertebrae of patients with severe osteoporosis. However, CBT technology has not been widely used, and there are still related problems that need to be clarified and further studied.

皮质骨轨迹（CBT）螺钉技术在临床应用之初以应用于老年腰椎退变性疾病为主，下腰椎单节段或双节段占大部分。随着技术熟练和器械改进，疾病种类不断拓展，并且能与传统椎弓根螺钉技术搭配使用，在邻椎病翻修微创治疗和重度骨质疏松患者椎体强化固定中发挥着重要的作用。然而，CBT技术并未得到广泛应用，仍有相关问题需要明确及进一步研究。本文就腰椎CBT螺钉技术的应用拓展及其相关问题进行论述。.
