简介:摘要目的深化对Kümmell病的认识,并探讨椎体后凸成形术治疗无神经症状Kümmell病的短期疗效。方法自2006年1月至2013年1月21例无神经症状Kümmell病患者接受球囊扩张椎体后凸成形术。分别于术前、术后记录Oswestry功能障碍指数(ODI)、疼痛视觉模拟评分(VAS)、伤椎和邻椎高度、受累节段矢状面Cobb角。结果患者术后3d、末次随访VAS平均评分分别为5.2±0.6、3.0±0.9,与术前比较均有显著统计学差异(P<0.05)。术后3d,末次随访ODI评分分别为59±8.0、14.8±6.8与术前比较均有显著统计学差异(P<0.05)。术后伤椎高度较术前明显增加,术后末次随访伤椎高度平均为20.0±2.9mm,与术前比较有显著统计学差异(P<0.05)。术后伤椎节段Cobb角较术前明显减小,术后末次随访时伤椎节段Cobb角平均为13.9±1.8°,与术前比较有显著统计学差异(P<0.05)。无明显并发症症,出现3例骨水泥渗漏,无症状,未给予处理。结论椎体后凸成形术是治疗无神经症状Kümmell病有效方法。
