摘要 目的 探讨应用人工腰椎间盘置换术治疗退变性腰椎间盘疾病的效果。方法 对 4 6例 5 4个间隙诊断为腰椎间盘退变性疾病的患者采用改良型SBChariteⅢ型人工腰椎间盘假体行置换术。结果 所有病例获得随访 ,随访时间 18~ 5 2个月 (平均 32 5个月 )。临床评价优 35例 ,良 9例 ,可 1例 ,差 1例。术后腰椎节段平均有 5 0 °(2 0~ 8 6 °)前屈和 6 2 °(4 2~ 9 8°)后伸活动 ,椎间隙高度较术前平均增加 4 0 (1 0~ 8.0 )mm。术后 9个月出现滑动核轻度前脱位 1例 ,但无临床症状。结论 人工腰椎间盘置换术为治疗腰椎间盘退变性疾病提供了一个疗效好而并发症少的新方法。 Objective To study the application of artificial intervertebral disc replacement for the treatment of degenerative lumbar disc diseases. Methods 46 cases (54 discs) with symptomatic degenerative lumbar disc diseases were diagnosed by CT,MRI and/or discography preoperatively and treated with artificial disc replacement using modified SB Charite Ⅲ prosthesis from April 1998 to June 2001. Results All patients were followed up to December 2002. The follow-up duration 18~52 months(average 32.5 months). There were 38 cases whose follow up time exceeded 24 months. The clinical results were excellent in 35 cases, good in 9 cases,fair in 1 case and fail in 1 case. The mobility of operated level had 5.0 °(2.0~8.6 °)anterior flexion and 6.2 °(4.2~9.8 °) posterior extension postoperatively. The disc space height of the operated level increased 4.0 mm in average. One case had slight displacement of the disc prosthesis postoperatively due to technique reason and without any clinical symptoms and signs. Conclusion Artificial disc replacement is a new procedure for the treatment of degenerative lumbar disc diseases with good results and a few complications. Long-term follow up is still needed.
