摘要
目的:评价运用可扩张型cage椎体间融合术治疗退行性腰椎疾病的价值。方法:对74例下腰痛患者,采用可扩张型腰椎椎间融合器共融合77个椎间隙,其中L3～43例;L4～543例;L5～S131例。3例需行2个椎节融合。结果:术后随访时间平均11.5个月,根据JOA评分:患者疗效优59.5%,良35.1%,中5.4%。影像随访结果显示,椎间高度术前(7.8±1.5)mm,术后椎间高度(12.0±0.8)mm;未发现融合器移位。结论:可扩张型cage是治疗退行性腰椎疾病的有效方法,良好的手术技巧和选择合适的cage是手术成功的必要条件。
Objoctive： To evaluate the effects of spinal fusion using expandable cage on treatment of lumbar degenetative disease. Methods： From May 2005 to Oct. 2006, 74 patients with low lumbar back pain underwent PLIF with expandable cage. For fusing site, 3 cases was at L3-4 inter＇vertebral space, 43 cases at L4-5, and 31 eases at L5-S1. Results： All patients were followed up from 3 to 19 months （averagely 11.5 months）. The intervertebral height was about 7.8±1.5 mm preoperatively, and 12.0±0.8 mm postoperatively under radiological detection. There were no transparent region at the interface or displacement between the vertebral body and the cage. Clinical results were satisfactory according to JOA scoring system. Coneltusions： Expandable cage is an effective tool on treating degenerated lumber disease. Excellent operative technique and appropriate choice of cages is the key point for a successful treatment.
