单侧PKP骨水泥双侧分布与单侧分布术后疗效的对比研究

摘要

目的：对30例行单侧PKP的胸12骨质疏松性压缩骨折病例（15例骨水泥呈双侧分布，15例骨水泥呈单侧分布）进行对比分析,观察术后椎体高度改变及术后腰痛缓解情况。方法总结我院2011、3～2013、3行单侧PKP治疗的胸12骨质疏松性压缩骨折手术病例30例（其中15例骨水泥呈双侧分布，15例骨水泥呈单侧分布）,按照术后影像学资料、VAS（Visual Analogue Scale）评分标准分别对患者术后椎体高度、术后疼痛进行比较。结果所有手术均顺利完成，无严重手术并发症，有5例发生骨水泥渗漏，均未出现临床症状。术后2周、1年时，两组病例椎体前后缘高度及VAS评分较术前均有显著性改善(P〈0.05)。术后2周时双侧分布组与单侧分布组对比，伤椎前后缘的高度改变无显著性差异，VAS评分有显著性差异(P〈0.05)。术后1年时两组VAS评分仍有显著性差异。结论两种不同的骨水泥分布方式对缓解骨质疏松性椎体压缩性骨折疼痛及恢复伤椎高度均有效，伤椎前缘高度的恢复方面二者无显著性差异，VAS评分的改善方面双侧分布组优于单侧分布组。对单侧PKP手术骨水泥呈单侧病例,可行对侧补充注射,以达到满意效果。%Objective To compare the clinical curative effects after unipedicular puncturing PKP with different bone cement distribution(unilateral distribution and bilateral distribution), to oberserve the change of the height of vertebralbody and pain. Methods 30 patients With OVCF from March 2011 to March 2013 were treated With unipedicular puncturing PKP.among whom 15 cases were with unilateral bone cement distribution and 15 cases were with bilateral bone cement distribution.The pain,height of vertebral body were compared according to VAS scoring, the measure of after PKP. Results Al the operations were successful without serious complications.After 10-12 months folow-up,the VAS scoring,imaging data of both two bone cement distribution(unilateral distribution and bilateral distribution) improved significantly than preopemtion(P
