摘　　要：目的探讨国产RSS脊柱内固定系统临床应用的有效性和安全性。方法对39例I～III度腰椎滑脱症患者先进行椎管减压,再应用国产RSS脊柱内固定系统进行滑脱椎体复位固定并椎体间植骨融合手术,术后定期复查,了解症状缓解、滑脱复位及复位丢失、植骨融合、内固定物松动或断裂情况。结果39例患者症状均明显改善,1例II度滑脱因骨质疏松未获复位,只进行原位融合固定,1例II度滑脱及1例III度滑脱恢复到I度,其余患者均获完全复位,复查结果显示,28例患者获I级骨性融合,平均融合时间10个月,11例获II级骨性融合。无复位后丢失现象及钉棒断裂、松动情况发生。结论国产RSS脊柱内固定系统结构简单,操作方便,用于治疗腰椎滑脱症可以使滑脱椎获得良好复位,并可维持椎体复位直到骨性融合,具有良好的术后稳定性。Objective To discuss the efficacy and safety of domestic spinal internal fixation system（RSS） using in lumbar spondylolisthesis. Methods 39 cases was included rang from Ⅰ to Ⅲ . After vertebral canal being decompressed, RSS was placed to reduce the spondylolisthetic vertebral body and intervertebral fusion was performed with a proper tricortical iliac crest autograft. Symptomatic relief was registered. Radiographs were analyzed regularly before surgery and after surgery to assess the success of spondylolisthetic vertebral body reduction,maintenance of correction, anterior fusion, internal fixation cinch or broken. Result Symptomatic relief was significant in all cases. 1 case with Ⅱ got in situ fusion for osteoporosis, lcase with Ⅱ and lcase with Ⅲ decreased to Ⅰ respectively. The others got spondylolisthetic vertebral body reduction completely. Follow-up revealed overall fusion was observed in 28 patients between 9 and 12 months（average： 10months）, partial remodeling with fusion was observed in 11 patients. There was no recurrence of lose of reduction,internal fixation cinch or broken. Conculusion Domestic spinal internal fixation system（RSS） was shown to be an effective device with its simple structure for lumbar spondylolisthesis in reduction rate and postoperative stability.
