摘　　要：目的 探讨腰椎滑脱复位术后2种不同植骨方法的疗效.方法 对46例腰椎滑脱患者进行椎管减压,采用RF-Ⅱ型椎弓根螺钉进行复位内固定,术后卧床2～3周后佩带腰围下床活动.根据术前、术后X线片和日本骨科学会（Japanese Orthopaedic Association,JOA）评分,评价2组植骨融合率及临床症状改善程度.结果 术后6个月A组融合率为90.90％,B组为79.17％,2组融合率差异有统计学意义（P＜0.05）;术后9、12个月2组融合率之间差异无统计学意义.术后6个月2组JOA评分差异无统计学意义.结论 RF-Ⅱ型复位内固定腰椎滑脱,虽然术后6个月稚间自体髂骨并咬除骨质椎间植骨融合率高于咬除骨并Cage椎间融合,但是2种融合方法均能达到满意的临床效果.Objective To compare the curative effect between 2 different bone grafting methods after lumbar spendylolysis RF screw-rod reduction. Methods Spinal canal decompression were enderwent on 46 cases with lumbar spondylolysis, processing reduction-fixation with RF- Ⅱ pedicle screw fixation. Twenty-two cases underwent intervertebral fusion with bited chips and autologous chunk of ilium as group A, 24 cases underwent intervertebral fusion with bited vertebral plate, spinous process and Cage as group B. Postoperative stay in bed for 2-3 weeks wear waist circumference. Bone grafting fusion rate and clinical symptoms improvement of 2 groups were evaluated by Japanese Orthopedic Association （JOA） scores and X-ray preoperative and postoperative. Results The bone grafting fusion rate （postoperative 6 months） was 90.90% m group A, and 79.17% in group B. The difference has statistical significance （P 〈0.05）. The difference of the bone grafting fusion rate between 2 groups has no statistical significance at postoperative 9 and 12 months. The difference of JOA scores between 2 groups has no statistical significance at postoperative 6 months. Conclusion Lumber spendylolysis reduction and internal fixation with RF- Ⅱ screw-rod, although the fusion rate of fusion with bited chips and autologous chunk of ilium is higher than with bited vertebral plate, spinous process and Cage at postoperative 6 months, these 2 methods can both satisfy the clinical result.
