Isobar TTL动态内固定系统治疗腰椎退行性疾病的临床疗效

目的探讨Isobar TTL动态内固定系统治疗腰椎退行性疾病的疗效。方法腰椎退行性疾病患者74例分为两组:A组,36例,行腰椎后路减压+Isobar TTL动态内固定系统固定术;B组,38例,用传统的腰椎后路减压+椎弓根钉棒系统固定术。随访2年,比较两组的临床疗效。结果两组手术时间、术中出血及并发症发生率相仿(P>0.05)。A组术后腰椎前凸角和骶骨倾斜角矫正值分别为(20.5±2.2)度和(15.8±2.9)度,均明显大于B组的(14.1±1.1)度和(12.3±2.2)度(P<0.05)。A组术后6个月、1年和2年后的JOA评分优良率分别为88.89%、94.44%和97.22%,均明显高于B组的65.79%、73.68%和76.32%(P<0.05)。结论 Isobar TTL动态内固定系统治疗腰椎退行性疾病的疗效优于传统的腰椎椎弓根钉棒系统固定。

Clinical outcomes of Isobar TTL dynamic stabilization system in the treatment of lumbar degenerative diseases

Objective To investigate the clinical outcomes of Isobar TTL dynamic stabilization system in the treatment of lumbar degenerative diseases.Methods A total of 74 patients with lumbar degenerative diseases was treated by decompressive surgery via posterior approach with Isobar TTL dynamic fixation operation(36 cases,group A) or with conventioal rigid fixation(38 cases,group B).The patients were followed up for 2 years and the clinical outcomes were compared.Results There was no difference in the operation time,intraoperative blood loss and complications of two groups were similar.The correct values of lumbar lordotic angle and sacral slope angle of group A were(20.5±2.2) degrees and(15.8±2.9) degrees,which were greater than(14.1±1.1) degrees and(12.3±2.2) degrees of group B(P<0.05).The excellence rates of JOA scores at 6 months,1 year and 2 years were 88.89%,94.44% and 97.22% in group A,which were greater than 65.79%,73.68% and 76.32% in group B(P<0.05).Conclusion Isobar TTL dynamic stabilization system is better than conventioal rigid fixation in the treatment of degenerative lumbar disease.
