文题释义:
安全区:
通过对临床资料的回顾性分析并参考相关文献及解剖学知识得出,在胸腰椎段椎体内有椎体静脉分布较稀疏区域,该区域内注射骨水泥可降低骨水泥渗漏率,并可注入相对较多的骨水泥,对今后手术操作和增强椎体硬度有重要意义。
骨水泥渗漏:是经皮椎体后凸成形手术最常见的手术并发症,常无明显临床表现,但严重者会导致肺栓塞、脊髓压迫甚至死亡。文章对行经皮椎体后凸成形手术患者进行回顾性分析,找寻减少骨水泥渗漏的方法,得出在椎弓根“2”点、“10”点方向进行穿刺,穿刺角度斜行向下,并在“安全区”内注射骨水泥可相对减少骨水泥渗漏的发生,对日后经皮椎体后凸成形手术操作有指导意义。


背景:研究发现,骨水泥渗漏大多与椎体后凸成形的手术操作及椎体静脉回流相关。
目的:结合胸腰段椎体血管分布规律,分析椎体后凸成形手术骨水泥渗漏率与手术操作的关系。
方法:回顾性分析行椎体后凸成形治疗的105例骨质疏松性椎体压缩骨折患者的临床资料,根据术中穿刺角度将患者分成A(斜行向下)、B(水平)、C(斜行向上)3组;根据骨水泥注射位置将患者分为1(安全区左侧)、2(安全区内)、3(安全区右侧)3组。观察各组骨水泥渗漏、骨水泥注入量、椎体高度恢复率、Cobb角恢复及疼痛改善情况。
结果与结论:①A组骨水泥总渗漏率、椎间静脉渗漏率少于B、C组(P < 0.05),骨水泥注入量高于B、C组(P < 0.05);术后第2天,3组间椎体高度恢复率、Cobb角恢复、疼痛评分比较差异无显著性意义;②2组骨水泥总渗漏率、椎间静脉渗漏率少于1、3组(P < 0.05),骨水泥注入量高于1、3组(P < 0.05);术后第2天,3组间椎体高度恢复率、Cobb角恢复、疼痛评分比较差异无显著性意义;③结果表明,椎体有相对恒定的“安全区”,改善穿刺角度及骨水泥注射位置,可减少椎体后凸成形的骨水泥渗漏。

Abstract:

BACKGROUND: Previous studies have shown that bone cement leakage rate is mainly associated with surgical procedure of kyphoplasty and vertebral venous reflux.

OBJECTIVE: To analyze the relationship between bone cement leakage rate and surgical procedure of vertebral kyphoplasty based on the distribution rule of thoracolumbar vessels.
METHODS: Clinical data of 105 patients treated with vertebral kyphoplasty for osteoporotic vertebral compression fractures (OVCFs) were retrospectively reviewed. All patients were divided into three groups according to the puncture angle: oblique downward position (group A), horizontal position (group B) and oblique upward position (group C). Then, the patients were divide into three groups according to the injection site of bone cement: the left side of safety zone (group 1), safety zone (group 2) and the right side of safety zone (group 3). Bone cement leakage rate, the amount of bone cement injected, the recovery rate of vertebral height and the recovery of Cobb angle and the improvement of pain were observed in each group.
RESULTS AND CONCLUSION: (1) The total rate of bone cement leakage and the rate of leakage via the vertebral vein in the group A were lower than those in the groups B and C (P < 0.05), and the amount of bone cement injected was higher than that in the groups B and C (P < 0.05). On the second day after surgery, there was no significant difference between the three groups in the recovery rate of vertebral height, the recovery of Cobb angle and visual analogue scale score. (2) The total rate of bone cement leakage and the rate of leakage via the vertebral vein in the group 2 were lower than those in the groups 1 and 3 (P < 0.05), and the amount of bone cement injected was higher than that in the groups B and C (P < 0.05). On the second day after surgery, there was no significant difference between the three groups in the recovery rate of vertebral height, the recovery of Cobb angle and visual analogue scale score. Overall, the results from this study confirm the existence of “safety zone” in the vertebra and indicate that management of puncture angel and injection site of bone cement can potentially reduce the cement leakage rate.
