This study aimed at delivering first clinical results after the use of a screw-and-PEEK rod system. Emphasis was placed on the ability of the construct to prevent adjacent segment disease at an average of 5 years follow up. The cohort was made up of 33 patients who received decompressive surgery in one segment and instrumentation with a screw-and-PEEK rod-based construct for stenosis of the lumbar spinal canal and a control group of 20 who received fusion surgery. At an average of 68 months follow up there were 19 patients where the symptoms had markedly improved or completely subsided. There were also nine patients where the symptoms initially subsided only to reoccur years later and five who had a subjective non-satisfactory result. The system showed no major disadvantage when compared to similar non-fusion pedicle-based techniques, nor was it able to consequently prevent ASD. Under a clinical point of view, there was, in our opinion, no marked benefit when compared against decompressive surgery and fusion as the accepted standard.
本研究旨在报告使用螺钉和聚醚醚酮（PEEK）棒系统后的首批临床结果。重点关注该结构在平均5年随访期内预防相邻节段疾病的能力。该队列由33例接受单节段减压手术并使用基于螺钉和PEEK棒的结构进行器械固定以治疗腰椎管狭窄症的患者，以及20例接受融合手术的对照组患者组成。平均随访68个月时，有19例患者症状明显改善或完全缓解。还有9例患者症状最初缓解，但数年后复发，5例患者主观结果不满意。与类似的非融合椎弓根技术相比，该系统没有明显劣势，也未能有效预防相邻节段退变（ASD）。从临床角度来看，我们认为与作为公认标准的减压手术和融合手术相比，该系统没有显著优势。
