【摘要】 目的评估Isobar TTL内固定系统治疗腰椎退行性疾病的临床疗效。方法回顾性分析自2007年11月~2010年12月应用Isobar TTL内固定系统治疗并获得随访的18例腰椎退行性疾病的临床资料。结果 18例获随访15~52个月,平均35个月。ODI术前评分为(24.00±10.52)分,末次随访时为(6.94±5.53)分(P<0.001);VAS评分术前为(7.89±0.90)分,末次随访时为(1.11±1.08)分(P<0.001);JOA评分术前为(7.33±5.18)分,末次随访时为(23.17±3.15)分(P<0.001)。动态固定节段椎间隙高度术前为(11.48±1.70)mm,末次随访时为(10.85±1.32)mm(P>0.05);椎间孔高度术前为(20.95±3.12)mm,末次随访时为(21.86±2.23)mm(P>0.05);ROM术前为(3.71±2.24)°,末次随访时为(2.72±1.90)°(P>0.05)。结论应用Isobar TTL内固定系统治疗腰椎退行性疾病临床疗效满意,融合节段均顺利获得融合,动态固定节段得到有效保护。更多还原

【Abstract】 Objective To evaluate the clinical effectiveness of Isobar TTL system in the treatment of degenerative lumbar diseases.Methods Between November 2007 and December 2010,18 consecutive patients with degenerative lumbar diseases were treated by decompression combined with Isobar TTL system and followed up.Results All patients were followed up for an average of 35 months(range,15~52 months).Preoperative ODI was(24.00±10.52),and the postoperative ODI was(6.94±5.53)(P <0.001).VAS score was reduced from(7.89±0.90) preoperatively to(1.11±1.08) postoperatively(P <0.001).The JOA score was improved remarkably from(7.33±5.18) preoperatively to(23.17±3.15) postoperatively(P <0.001).The intervertebral space height was slightly decreased from(11.48±1.70)mm preoperatively to(10.85±1.32)mm postoperatively(P >0.05),and the foraminal height was changed a little from(20.95±3.12)mm to(21.86±2.23)mm(P >0.05).The ROM was also not obvious from(3.71±2.24)° preoperatively to(2.72±1.90)° postoperatively(P >0.05).Conclusion The Isobar TTL system shows the clinical benefits.And it minimizes accelerated degeneration at protected levels,which appears to be a useful and effective manner for the treatment of degenerative lumbar diseases.更多还原
