Pedicle screw and rod instrumentation has become the preferred technique for performing stabilization and fusion in the surgical treatment of lumbar spine degenerative disease. Rigid fixation leads to high fusion rates but may also contribute to stress shielding and adjacent segment degeneration. Thus, the use of semirigid rods made of polyetheretherketone (PEEK) has been proposed. Although the PEEK rods biomechanical properties, such as anterior load sharing properties, have been shown, there are few clinical studies evaluating their application in the lumbar spine surgical treatment. This study examined a retrospective cohort of patients who underwent posterior lumbar fusion for degenerative disease using PEEK rods, in order to evaluate the clinical and radiological outcomes and the incidence of complications.
椎弓根螺钉和棒系统已成为腰椎退行性疾病手术治疗中进行稳定和融合的首选技术。刚性固定可导致高融合率，但也可能导致应力遮挡和相邻节段退变。因此，有人提出使用聚醚醚酮（PEEK）制成的半刚性棒。尽管已显示出PEEK棒的生物力学特性，如前负荷分担特性，但很少有临床研究评估其在腰椎手术治疗中的应用。本研究对一组使用PEEK棒行后路腰椎融合术治疗退行性疾病的患者进行回顾性队列研究，以评估临床和影像学结果以及并发症的发生率。
