摘　　要：目的]探讨经后路采用RF椎弓根系统治疗腰椎滑脱症的效果。[方法]自1999年2月～2003年12月,39例腰椎滑脱症的患者经后路采用RFⅡ椎弓根螺钉系统进行减压融合手术治疗,其中Ⅰ度滑脱12例,Ⅱ度滑脱18例,Ⅲ度滑脱9例;退变性腰椎滑脱22例,峡部裂性腰椎滑脱17例。[结果]所有患者术后随访均超过12个月,平均(27.6±7.2)个月。比较手术前后临床症状及X线片。根据Asher的疗效观察项目:优22例,良13例,可3例,差1例,优良率达89.7%。并发症共6例,其中术中并发症3例,发生率为7.7%;术后并发症3例,发生率为7.7%。[结论]经后路采用RF椎弓根螺钉系统能使腰椎滑脱得到较为确实的复位和固定,脊柱融合率高,临床效果满意。[ Objective] To evaluate the clinical effect of lumbar spondylolisthesis treated by posterior vertebral body fusion - ,/ and RF-Ⅱ pedicle screw＇spinal system . [ Method] From February 1999 to December 2003, 39 cases of lumbar spondylolisthesis were included in this study. According to Meyerding classification, roentgengram showed that there were 12 cases of grade Ⅰ, 18 cases of grade Ⅱ , 9 cases of grade Ⅲ, 22 cases of degenerative spondylolisthesis and 17 cases of spondylolysis. All patients were treated with posterior decompression of total laminectomy and bilateral nerve canal, intertransverse process arthrodesis were managed by means of bone chip grafting, interbody fusion was done with RF- Ⅱ pedicle screw spinal system, The clinical results and complications were evaluated and a radiographic assessment was performed. [ Result] All the patients were followed up over 12 months postoperative （ averaged 27.6 ± 7.2 months）. According to the criteria of Asher, the therapeutic effect was excellent in 22 cases, good in 13 cases, fair in 3 cases, and poor in 1 case. The satisfactory rate was 89.7% . Complications occurred in six cases, in which three cases occurred during operation with the incidence rate of 7. 7%, while three occurred after operation with the incidence rate of 7.7%. [ Conclusion] Posterior interbedy fusion and RF pedicle screw spinal system provide fixation with satisfactory clinical results and relatively high fusion rate.
