摘要:

背景:经皮椎体后凸成形因在修复伤椎的同时可以降低治疗后局部及静脉骨水泥渗漏发生的风险而被逐渐用于重度骨质疏松性椎体压缩性骨折。研究发现当骨水泥混合后,在其如面团状高黏度状态时注射入椎体可明显减少骨水泥的渗漏量。
目的:比较应用高黏度骨水泥行经皮椎体成形与标准黏度骨水泥行经皮椎体后凸成形治疗重度骨质疏松性胸腰椎骨折的临床疗效。
方法:选取重度骨质疏松性胸腰椎骨折的患者80例,随机分为经皮椎体成形组和经皮椎体后凸成形组,每组各40例,分别应用经皮椎体成形和经皮椎体后凸成形修复椎体,组内治疗前后及组间比较两组患者目测类比、Oswestry功能障碍指数及治疗后骨水泥渗漏等并发症发生率。
结果与结论:治疗后组间目测类比评分比较无显著差异(P > 0.05);2组患者脊柱功能恢复良好,治疗后3个月组间Oswestry功能障碍指数指数比较无明显差异(P > 0.05);治疗后骨水泥渗漏发生率经皮椎体成形组45%,经皮椎体后凸成形组30%,经皮椎体成形组骨水泥渗漏发生率高于经皮椎体后凸成形组(P < 0.05),但均未见明显临床症状,未予处理;所有患者术后均无肺栓塞、骨水泥毒性反应、脊髓及神经根损伤等并发症。结果说明,在以经皮椎体成形治疗重度骨质疏松性胸腰椎骨折中应用高黏度骨水泥能显著改善患者背部疼痛症状,恢复脊柱功能,修复后骨水泥渗漏等并发症发生率及临床疗效与经皮椎体后凸成形无明显差异。

Abstract:

BACKGROUND: Because it can reduce the risk of postoperative bone cement leakage, percutaneous kyphoplasty is increasingly used for treatment of severe osteoporotic thoracolumbar vertebral compression fractures. Studies have found that injection of mixed bone cement with high viscosity can significantly reduce the leakage of bone cement.

OBJECTIVE: To compare the therapeutic efficacy of percutaneous vertebroplasty with high viscosity bone cement and percutaneous kyphoplasty with standard viscosity bone cement in the treatment of severe osteoporotic thoracolumbar vertebral compression fractures.
METHODS: Eighty patients with severe osteoporotic thoracolumbar vertebral compression fractures were enrolled and randomized into vertebroplasty group and kyphoplasty group, 40 patients in each group. Visual analog scale score and Oswestry disability index score were compared between groups before and after treatment. Incidence rate of bone cement leakage and other complications were also compared between two groups after treatment.
RESULTS AND CONCLUSION: No significant difference was found between the visual analog scale scores of two groups after treatment (P > 0.05). Patients in the two groups all presented with good recovery of spinal function after treatment, and there was no difference in the Oswestry disability index scores between groups at 3 months after treatment (P > 0.05). The incidence rate of bone cement leakage was 45% in the vertebroplasty group and 30% in the kyphoplasty group, with a significant difference (P < 0.05). But the patients in both groups showed no obvious clinical symptoms and underwent no treatment. After treatment, all patients had no pulmonary embolism, bone cement toxicity, spinal cord and nerve root injury. These findings show that there is no significant difference between percutaneous vertebroplasty and kyphoplasty with high-viscosity bone cement in the following aspects: pain improvement, recovery of the spinal function, incidence rate of bone cement leakage and clinical efficacy.
