人工腰椎间盘置换手术适应证探讨

Indications for Artificial Intervertebral Disc Replacement

目的 :探讨人工腰椎间盘置换手术的适应证。方法 :采用人工腰椎间盘置换术治疗腰椎间盘突出症腰腿痛患者 2 0例 ,随访 6～ 2 9个月 (平均 1 6 .5个月 ) ,对手术疗效进行评价。结果 :2 0例患者症状体征均显著改善 ,手术优良率达 1 0 0 %。术后X线片显示椎间隙高度恢复正常 ,人工椎间盘假体位置良好。无血管神经损伤、假体松动移位、椎间隙高度丢失和感染等并发症。结论 :腰椎间盘突出引起的腰腿痛是人工腰椎间盘置换术的主要适应证之一。

Objective:To study the indications for artificial intervertebral disc replacement.Methods:Twenty patients with back and leg pain caused by lumbar intervertebral disc herniation were treated by artificial disc replacement.All patients were followed up for 6～29 months(averaged 16.5 months).The clinical outcomes were assessed.Results:Subjective symptoms and clinical signs of patients were obviously improved.The excellent rate was 100%.X ray film confirmed that the intervertebral height recovered and the prosthesis lied in accurate position.There was no neurovascular injury,no prosthesis was lost or dislocated.No intervertebral height lost or infection occurred.Conclusion:The back and leg pain caused by lumbar intervertebral disc herniation is a main indication of artificial disc replacement.
