文题释义:
椎体成形术:是指通过向骨折椎体内注入相应的生物材料(如骨水泥等)达到缓解疼痛,矫正椎体畸形,增加椎体稳定性的手术方式。其作为一种症状缓解迅速、疗效确切且对患者身体素质要求不高的骨科微创手术方式,在老年患者骨质疏松性骨折的临床治疗中得到广泛应用。
骨质疏松椎体压缩性骨折:主要是指由于病理生理因素改变,导致骨量减少,骨组织微结构退变,骨组织强度下降、脆性增加的全身骨代谢异常疾病,临床主要表现为全身疼痛、骨折及脊柱畸形等,老年患者(尤其是绝经后的女性)是高发人群,由于卧床保守治疗的并发症较多、较重,目前临床主要通过椎体成形术治疗,早期纠正脊柱畸形、恢复功能活动。
 
 
背景:高黏度骨水泥是在传统聚甲基丙烯酸甲酯的基础上改进得到,具有可注射时间长、黏度高、聚合温度低等特点,进一步增加了椎体成形手术的安全性。
目的:分析椎体成形治疗老年女性骨质疏松椎体压缩性骨折中高黏度骨水泥弥散程度对临床疗效的影响。
方法:纳入120例女性首次、单一节段骨质疏松椎体压缩性骨折患者,年龄53-83岁,均进行高黏度骨水泥椎体成形手术。根据术后侧位X射线片将骨水泥弥散至上下终板两侧的患者记为A组(n=54),其他患者记为B组(n=66);根据CT横断位骨水泥弥散情况,将A组中均匀弥散至双侧椎弓根的患者记为Ⅰ度,其他患者记为Ⅱ度。术后所有患者均随访6个月以上,对比各组末次随访的椎体前缘高度恢复率、局部后凸角改善率、目测类比评分与Oswestry功能障碍指数评分。

结果与结论:①A组末次随访的椎体前缘高度恢复率、末次随访局部后凸角改善率均高于B组(P < 0.05);②末次随访时,A、B组目测类比评分与Oswestry功能障碍指数评分均较治疗前明显改善(P < 0.05),两组间比较差异无显著性意义(P > 0.05);③Ⅰ度组与Ⅱ度组末次随访的椎体前缘高度恢复率、局部后凸角改善率比较差异均无显著性意义(P > 0.05);④A组中骨水泥渗漏9例,术后发热4例,低血压2例;B组中骨水泥渗漏8例,发热6例,术后血压升高2例,术后皮肤浅层渗液1例,两组间不良反应发生情况比较差异无显著性意义(P > 0.05);⑤结果表明,高黏度骨水泥椎体成形治疗老年女性单节段骨质疏松椎体压缩性性骨折疗效肯定,骨水泥弥散程度愈高临床疗效愈佳,但高黏度骨水泥的注入要适量,过多的弥散会增加渗漏风险。

Abstract:

BACKGROUND: High-viscosity bone cement is modified on the basis of traditional polymethylmethacrylate with the long injection time, high-viscosity and low polymerized temperature feature and further improves the safety of percutaneous vertebroplasty.

OBJECTIVE: To analyze the effect of high-viscosity bone cement dispersion on the clinical outcomes in elderly female patients with osteoporotic vertebral compression fracture who have undergone percutaneous vertebroplasty.
METHODS: Totally 120 elderly female patients with primary single-segmental osteoporotic vertebral compression fracture aged from 53 to 83 years were included, and percutaneous vertebroplasty with high-viscosity bone cement was performed in all the enrolled patients. The patients were assigned into two groups according to the bone cement dispersion shown on the lateral X-ray film. The bone cement dispersed to both endplates in the fractured vertebral bodyof 54 patients, who were marked as group A, and the other 66 patients were classified as group B. The group A patients were further divided into two subgroups in term of CT cross-sectional image, and the patients with the bone cement dispersing to the bilateral pedicles were taken as degree I (25 patients) and the others were termed as degree II (29 patients). All patients were followed up for more than 6 months, and the recovery rate of anterior height of the vertebra, local kyphosis angle improvement rate, visual analog scale scores and Oswestry dysfunction index score at the last follow-up were compared among groups.

RESULTS AND CONCLUSION: (1) The recovery rate of anterior height of the vertebra and local kyphosis angle improvement rate in group A were better than those in group B at the last follow-up (P < 0.05). (2) The visual analog scale scores and Oswestry dysfunction index scores in both A and B groups were significantly improved at the last follow-up compared to the baseline data (P < 0.05), but there was no significant difference between the two groups (P > 0.05). (3) The subgroups of degree I and II showed no significant difference in the recovery rate of anterior height of the vertebra and local kyphosis angle improvement rate at the last follow-up (P > 0.05). (4) There were nine patients with bone cement leakage, four patients with postoperative fever, two patients with low blood pressure in group A and eight patients with bone cement leakage, six patients with postoperative fever, two patients with high blood pressure, one patient with superficial skin infection in group B, but there was no significant difference in the postoperative complications between the two groups (P > 0.05). All the results suggest that percutaneous vertebroplasty with high-viscosity bone cement has positive efficacy in treating elderly women with single-segmental osteoporotic vertebral compression fracture. The better dispersion of bone cement in the fractured vertebrae indicates the better clinical effects. However, high-viscosity bone cement should be injected in an appropriate amount, as excessive dispersion will increase the risk of leakage.
