Lumbar degenerative disc disease (DDD) in the elderly population remains a global health problem, especially in patients with osteoporosis. Osteoporosis in the elderly can cause failure of internal fixation. Cortical bone trajectory (CBT) is an effective, safe and minimally invasive technique for the treatment of lumbar DDD in patients with osteoporosis. In this review, we analyzed the anatomy, biomechanics, and advantages of the CBT technique in lumbar DDD and revision surgery. Additionally, the clinical trials and case reports, indications, advancements and limitations of this technique were further discussed and reviewed. Finally, we concluded that the CBT technique can be a practical, effective and safe alternative to traditional pedicle screw fixation, especially in DDD patients with osteoporosis.
老年人群中的腰椎退行性椎间盘疾病（DDD）仍然是一个全球性的健康问题，尤其是在骨质疏松症患者中。老年人的骨质疏松症可导致内固定失败。皮质骨轨迹（CBT）是治疗骨质疏松症患者腰椎DDD的一种有效、安全且微创的技术。在本综述中，我们分析了CBT技术在腰椎DDD及翻修手术中的解剖学、生物力学和优势。此外，还进一步讨论和回顾了该技术的临床试验和病例报告、适应证、进展及局限性。最后，我们得出结论，CBT技术可以成为传统椎弓根螺钉固定的一种实用、有效且安全的替代方法，尤其是对于患有骨质疏松症的DDD患者。
