摘要
目的:探讨Isobar TTL动态内固定系统及传统坚强内固定治疗腰椎退行性疾病的临床疗效。方法:选取98例行腰椎退行性疾病手术治疗的患者,分为两组,试验组52例行腰椎后路减压+IsobarTTL动态内固定系统固定术;对照组46例行传统的腰椎后路减压+椎弓根钉棒系统固定术。比较两组手术时间、术中出血量及相关并发症发生率,测量术前、术后腰椎前凸角及骶骨倾斜角改变,术后随访3年,观察相邻节段退变情况,行日本骨科协会评分(JOA评分)对比观察临床疗效。结果:两组术后腰椎前凸角矫正分别为(22.8±2.7)°、(13.9±1.6)°,骶骨倾斜角矫正值分别为(15.9±2.7)°、(12.2±2.6)°,试验组明显大于对照组(P<0.05);手术时间、术中出血及并发症发生率两组比较差异无统计学意义(P>0.05);两组术后早期JOA评分(术后1个月)比较差异无统计学意义(P>0.05)。试验组术后3个月、1年、2年、3年的JOA评分优良率与对照组比较差异有统计学意义(P<0.05),随访3年,试验组相邻节段退变明显低于对照组(P<0.05)。结论:Isobar TTL动态内固定系统可取得较好的临床疗效,更好的恢复腰椎稳定性,减轻临近节段的退变。
Objective ： To investigate the clinical effect of isobar TTL dynamic stabilization system compared to rigid fixation system in the treatment of the degenerative diseases of lumbar by 3-year follow-up.Methods ： A total of 98 patients with lumbar degenerative diseases had surgical treatment, 52 patients underwent Isobar TTL dynamic fixation operations（experimental group）, 46 patients underwent rigid fixation operations （control group）.The operation time, intraoperative blood loss and complications were recorded, The correct of the lumbar lordotic angle and sacral slope angle were observed from X-ray film.The clinical effect and ASD（adjacent segment degeneration）situation was evaluated by JOA scoring system.Results ： The correct of the lumbar lordotic angle were obvious in the experimental group （（22.8 ±2.7）° VS （13.9 ±1.6）°, P〈0.05））as well as sacral slope angle （（15.9 ± 2.7）° VS （12.2 ±2.6）°, P〈0.05））.There were no difference in the operation time, intraoperative blood loss and complications in two groups（P〉0.05）.Regarding clinical effect, JOA score showed in the first month no differences were found in two groups（P〉0.05）, however after 3 months a higher score was observed in the experimental group at 6th month, 1st year, 2nd year, 3rd year during the 3-year clinic follow-up（P〈0.05）.And a lower rate in ASD was found for 3-year clinic follow-up（P〈0.05）.Concluslon ： Isobar TTL dynamic stabilization system has satisfactory clinical effects in the treatment of degenerative lumbar disease, which could reconstruction the stability of the spine better and reduce adjacent segment degeneration.
