目 的 :观察RF -Ⅱ型椎弓根螺钉系统加横突间植骨治疗腰椎滑脱的疗效。方法 :自 1998年 2月～ 2 0 0 1年 2月采用RF -Ⅱ型椎弓根螺钉系统复位内固定加横突间植骨术治疗腰椎滑脱症 2 1例 ,男性 15例 ,女性 6例 ,峡部型 17例 ,退变型 3例 ,创伤型 1例 ,Ⅰ度 5例 ,Ⅱ度 12例 ,Ⅲ度 4例 ,滑脱部位L515例 ,L4 6例。结果 :全部病例均获随访平均 3.2年 ( 2 .4～5年 ) ,复位率 90 %～ 10 0 % ,无感染 ,无神经根损伤或神经症状加重 ,术前畸形得以改善 ,19例术前症状消失 ,2 0例 ( 95 % ) 4～ 6个月脊柱融合。结论 :RF -Ⅱ系统强度可靠 ,三维固定方式理想 ,可明显提高横突间植骨的融合率 ,是目前治疗腰椎滑脱的理想方式。
Objective:To study the results of treatment for lumbar spondylolisthesis with RF-II pedicle screw system and intertransverse lumbar fusion. Methods:Twenty-one patients with isthmic(17cases), degenerative(3 cases), and post-traumatic(1 case) spondylolisthesis were treated with RF-Ⅱ pedicle screw system and intertransverse lumbar fusion. Five patients were classified as Degree Ⅰ lesion, 12 as Degree Ⅱ lesion, and 4 as Degree Ⅲ lesion. Results: All patients had been followed up to an averaged of 3.2 years (range 2.4～5years). The percentage of the patients who got excellent and good recovery was above 90%. Clinical symptoms of 19 cases were relieved.X-ray examinations confirmed good fusion effect (95%) with satisfactory spinalstability. Conclusion:RF-Ⅱ pedicle screw fixation system has the strongest three-dimensional rigidity, and is easy to obtain a simple and an effective reduction on the spondylolisthesis. Additionally, the application of the system can obtain a good spinal fusion.
