| ［摘要］ 目的 探讨RF-Ⅱ型椎弓根螺钉系统内固定加椎间植骨联合后外侧关节突和横突间植骨融合对腰椎滑脱症的治疗效果。方法 对37例腰椎滑脱症患者采用RF-Ⅱ型椎弓根螺钉进行复位内固定行椎板切除减压和髓骸摘出，同时行椎间植骨联合后外侧关节突和横突间植骨融合，术后卧床休息6～8周后佩带腰围下床活动。结果 随访半年至3年，平均27个月，滑脱椎体平均复位率86.0%(80%～100%)，经X线检查，37个椎间隙的融合率为97.6%，术后症状基本消失，植骨均融合，无固定螺钉松动、断裂及再滑脱现象，优良率达83.5%。结论 RF-Ⅱ型椎弓根螺钉内固定系统治疗腰椎滑脱症效果满意。 |

| Abstract: |
| ［Abstract］ Objective To investigate the therapeutic effcts of RF-Ⅱ type pedicle screw systems fixation and posterior lumbar interbody fusion with bone grafting for the lumbar spondylolisthesis.Methods Thirty-seven cases of lumbar spondylolisthesis were treated with RF-Ⅱ-for pedicle screw reduction and internal fixation, decompression laminectomy and wrecked marrow extraction. At the same time, after the intervertebral bone joint, articular process fusion between lateral transverse process were performed.After 6 to 8 weeks of surgery the patients were allowed out of bed with waist.Results The patients were followed up six months to 3 years, an average of 27 months. The average rate of vertebral spondylolisthesis reduction was 86% (80%～100%).By the X-ray examination, there were a intervertebral space fusion rate of 97.6% in 37 vertebral bodies, patients′ symptoms disappeared.Both bone fusion were good, without a fixed screw loosened, re-slipped and faulted.Good rate was 83.5%. Conclusion The effects of RF-Ⅱ type pedicle screw fixation for the treatment of lumbar spondylolisthesis is satisfying. |
