. Spinal fusion has been shown to be the preferred surgical option to reduce pain, recover function, and increase quality of life in the treatment of a variety of lumbar spinal disorders. The main goal of the present study is to report our clinical experience and results of percutaneous transforaminal endoscopic lumbar interbody fusion (PELIF) applications using the expandable spacer in a single institution. . We performed a retrospective review of 18 patients with >12-month follow-up who had been operated on PELIF using expandable spacer from 2001 to 2007. Their clinical and radiological data were collected and analyzed. . The mean follow-up period was 46 months. The mean DH before the surgery was 8.3 mm which improved to 11.4 mm at the early postoperative period and regressed to 9.3 mm at the last follow-up visit. The VAS-B, VAS-L, and ODI scores at the last follow-up showed a 54%, 72%, and 69% improvement from the preoperative period, respectively. . The presented PELIF technique with the expandable spacer seems to be a promising surgical technique for the treatment of a variety of lumbar spinal disorders. Conversely, radiological results including disc space subsidence make the stand-alone application of the expandable spacer debatable.
脊柱融合术已被证明是治疗各种腰椎疾病时减轻疼痛、恢复功能和提高生活质量的首选手术方式。本研究的主要目的是报告我们在单一机构中使用可扩张椎间融合器进行经皮椎间孔镜腰椎椎间融合术（PELIF）的临床经验和结果。我们对2001年至2007年期间接受使用可扩张椎间融合器的PELIF手术且随访超过12个月的18例患者进行了回顾性研究。收集并分析了他们的临床和影像学数据。平均随访期为46个月。术前平均椎间隙高度为8.3毫米，术后早期改善至11.4毫米，末次随访时回落至9.3毫米。末次随访时的VAS-B、VAS-L和ODI评分较术前分别改善了54%、72%和69%。所介绍的使用可扩张椎间融合器的PELIF技术似乎是治疗各种腰椎疾病的一种有前景的手术技术。相反，包括椎间隙塌陷在内的影像学结果使得可扩张椎间融合器的单独应用存在争议。
