人工颈椎间盘置换术治疗脊髓型颈椎病的临床观察

Clinical outcome of cervical arthroplasty in the treatment of spondylotic myelopathy

[目的]研究确定颈椎人工椎间盘置换术对脊髓型颈椎病的治疗效果。[方法]对2004年1月．2005年8月间于本院行颈椎人工间盘置换术的12例脊髓型颈椎病患者手术前后的Nurick分级，ONDI评分、颈项和上肢疼痛VAS评分进行比较评估，并采用Odom标准评价手术效果。[结果]本组患者术后Odom优良率达100％，术后Nurick分级、ONDI评分、颈项疼痛VAS评分、上肢疼痛VAS评分均较术前有显著意义的提升（P〈0．01）。[结论]对于1～2个节段的脊髓型颈椎病，颈椎人工椎间盘置换术在维持节段运动功能的同时可取得良好的神经减压效果。

[ Objective] To verify the clinical outcome of cervical arthroplasty in the treatment of spondylotlc myelopathy exclusively. [ Method] From January 2004 to August 2003, twelve spondylotic myelopathy patients who underwent cervical arthroplasty were included in this study. Preoperative and final follow-up Nuriek grade, Oswestry neck disability index （ONDI） score, neck and arm pain VAS score of patients were recorded and compared. Surgical outcome was also measured using odom＇s criteria. [ Result] 100% of patients had good or excellent outcomes using Odom＇s criteria, while the final follow-up Nurick grade, ONDI score, neck and arm pain VAS score were improved significantly compared with the preoperative valule. [ Conclusion ] Cervical arthroplasty is effective in the treatment of spinal cord compression secondary to spondylotic disease with interveterbral movement being preserved.
