摘要(Abstract)：

[目的]观察单节段腰椎后路椎间融合联合邻近节段K-Rod动态固定术治疗腰椎退行性疾病的临床疗效。[方法]回顾性分析2010年6月~2012年9月手术治疗的50例腰椎退行性疾病患者的临床资料,根据手术方式不同分为2组:单节段腰椎后路融合联合邻近节段K-Rod动态固定术组(A组)和单节段腰椎后路融合术组(B组),其中A组男14例,女11例;平均年龄(41.2±5.6)岁;B组男12例,女13例;平均年龄(47.4±5.2)岁。评估两组患者的神经改善情况、腰椎总活动度、近端邻近节段活动度及椎间隙高度情况。[结果]随访时间12~25个月,平均16.7个月。无不可逆性神经症状加重、内置物失败等并发症,临床疗效满意。在末次随访时,两组患者术后VAS及ODI评分均获得显著改善(P<0.05);A组动态固定节段的活动度术前(8.50±0.76)°,末次随访(3.45±0.49)°,存在统计学差异(P<0.05);A组动态固定节段的近端临近节段的活动度术前(7.62±0.50)°,末次随访(7.87±0.62)°,无统计学差异;B组近端临近节段活动度术前(8.20±1.13)°,末次随访(8.90±1.03)°,存在统计学差异(P<0.05);在末次随访时,两组腰椎总活动度及椎间隙高度均无统计学差异(p>0.05)。[结论]腰椎后路融合联合邻近节段K-Rod动态固定术治疗腰椎退行性疾病早期疗效明确,能够维持一定的脊柱生物学功能,并能避免相邻节段退变的进展,但远期疗效有待进一步观察。
