RF-Ⅱ复位内固定BAK椎间融合治疗椎体滑脱

RF-II Correcting Internal Dislocation and BAK Fusion Treating Lummar Spondylolithesis Dislocation

目的 探讨应用RF -Ⅱ与BAK治疗腰椎体滑脱症的效果。方法 对 2 6例腰椎体滑脱患者行手术治疗 ,其中I度滑脱 3例 ,Ⅱ度滑脱 16例 ,Ⅲ度滑脱 7例。均伴有神经症状 ,严格保守治疗无效。采用后路减压RF -Ⅱ复位固定、BAK椎间融合、椎板回植方法。结果 所有患者滑脱椎体得到复位 ,椎体融合率达 92 .3%,神经症状消失。术后随访平均 15个月 ,其中优 9例、良 4例、可 1例、差 2例。结论 RF -Ⅱ系统可使椎体完全复位 ,恢复了脊椎生物力学功能 ,解除了神经压迫。同时增加了融合面积 ,利于椎体融合。

Objective To summarize the effect of lummar spondylolisthesis treated by RF-Ⅱ and BAK. Methods 26 cases were operated,3 cases were grade Ⅰ,16 cases were grade Ⅱ,7 cases were grade Ⅲ.All the cases had nerve function obstical,and conservative treatment was not effective.Postterior discompression, RF-Ⅱ correcting dislocation and fixing BAK fuse,vertebra board replanted. Results All the cases were corrected dislocation,the rate of fusion was 92.3%,nerve function recoveried.All the cases were followed up for 15 months(7～20 months).Of them 9 cases recovered exactlly,4 cases well recovered,1 case recovered commonly,2 cases recovered unsatisfactorily. Conclusion RF-Ⅱ system can corrent dislocation completely,and recover the thysiological function of spine,and release the pressure of nerve. RF-Ⅱ system increases the area of fusion and as is benefitial to fusion.
