摘要
目的对Tenor椎弓根内固定系统治疗腰椎滑脱症进行评估。方法自2001年2月~2004年8月,对42例Ⅰ~Ⅱ度腰椎滑脱症患者采用后路椎管减压、Tenor椎弓根内固定系统复位固定和侧后方植骨融合术。结果40例经平均2.5年(1~4.5年)随访。30例Ⅰ度滑脱和7例Ⅱ度滑脱完全复位(占所有病例的92.5%),另3例Ⅱ度滑脱复位达90%,解剖复位率为92.5%。融合率按Lenke标准:A级65%,B级22.5%,C级12.5%;疗效按Henderson标准评价:优72.5%,良20%,可5%,差2.5%。结论Tenor椎弓根内固定系统操作简单,固定牢固,适用于Ⅰ~Ⅱ度腰椎滑脱症的手术治疗。
Objective To evaluate the efficacy of Tenor pedicle screw system in lumbar spondylolisthesis. Methods From February 2001 to August 2004, 42 patients with Meyerding grade Ⅰ and Ⅱ spondylolisthesis treated by posterior lumbar canal decompression and reduction with Tenor pedicle screw system and fusion with posterolateral bone grafting were reviewed. Results Forty patients were Collowed up from 1 year to 4.5 years with average of 2.5 years. Thirty two patients with grade Ⅰ and 7 of 10 patients with grade Ⅱ obtained the complete reduction of the slide intervertebral body. Anatomical reduction rate was 92.5 %. The other 3 patients with grade Ⅱ obtained 90 % of reduction. By Lenke standard,the fusion was A in 65 %, B in 22.5 % and C 12.5 %. By Herderson standard, the result was excellent in 72.5 % ,good in 20 % ,fair in 5 % and poor in 2.5 %. Conclusion Tenor pedicle screw system is a good spinal fixation system for the treatment of grade Ⅰ and Ⅱ lumbar spondylolisthesis with the characteristics of strong fixation and simplicity.
