两种术式治疗骨质疏松性胸腰椎压缩性骨折效果比较

THORACOLUMBAR OSTEOPOROTIC VERTEBRAL COMPRESSION FRACTURES:A COMPARISON BETWEEN PERCUTANEOUS KYPHOPLASTY AND PERCUTANEOUS VERTEBROPLASTY

目的比较经皮椎体后凸成形术（PKP）与经皮椎体成形术（PVP）治疗骨质疏松性胸腰椎压缩性骨折的效果。方法我院骨质疏松性胸腰椎压缩性骨折住院病人106例,随机分为两组,分别采用PKP及PVP进行治疗。比较两组病人治疗后椎体前缘高度、椎体后凸角度及疼痛强度视觉模拟评分（VAS）的变化。结果两组病人术后3d及3月各项指标均较术前有明显改善（F=236.68～6 232.42,P〈0.05）;两组病人术后3d及3月VAS评分比较差异无显著性（P〉0.05）。术后3d及3月PKP组椎体前缘高度和椎体后凸角度指标改善情况好于PVP组（F=37.40～45.36,P〈0.05）。结论 PKP与PVP治疗骨质疏松性胸腰椎压缩性骨折,均能有效地改善病人疼痛,但在病人畸形矫正方面PKP优于PVP。

Objective To compare the efficacy between percutaneous vertebroplasty （PVP） and percutaneous kyphoplas- ty （PKP） in the treatment of thoracolumbar osteoporotic vertebral compression fractures （TLOVCF）. Methods This study consisted of 106 patients with TLOVCF, who were divided into two groups in random and treated with PKP and PVP, respectively. Postoperative height of vertebral anterior border and vertebral kyphosis angle, vertebral kyphosis and visual analogue pain intensity scale （VAS） were compared between the two groups. Results The findings of 3 days and 3 months after surgery were： each marker in both groups was much improved （F=236.68 6 232.42,P〈0.05）, but the difference in VAS score between the two groups was not significant （P〉0.05）. However, the height of vertebral anterior border and vertebral kyphosis angle in the PKP group were better than that in the PVP group （F = 37.40- 45.36, P 〈0.05 ）. Conclusion Both PKP and PVP can reduce the pain in patients with thoracolumbar osteoporotic vertebral compression fractures, but PKP is better than PVP with regard to de- formity correction.
