文题释义:
胸腰椎转移肿瘤:脊柱椎体是恶性肿瘤较为常见的转移部位,其中以累及胸椎者最为常见(约占63%),其次为腰椎及颈椎(分别约占27%和10%)。转移瘤的生长与浸润可造成椎体骨质结构破坏,导致病理性骨折,部分患者出现脊髓或神经压迫症状,伴有腰部或相应神经支配区的剧烈疼痛,有些脊髓压迫甚至可造成患者不同程度的瘫痪。
经皮穿刺椎体成形:经皮通过椎弓根或椎弓根外向椎体内注入骨水泥以达到增加椎体强度和稳定性、防止塌陷、缓解疼痛、甚至部分恢复椎体高度为目的一种微创脊椎外科技术。研究采用2种黏度骨水泥治疗脊柱椎体转移肿瘤,通过影像学、疼痛评分及临床功能对比评价2种材料的优劣。
 
 
背景:经皮穿刺骨水泥椎体成形治疗恶性肿瘤胸腰椎转移的骨水泥渗漏等并发症较为常见,不同填充材料的选择成为影响手术疗效的重要因素。
目的:探讨不同黏度骨水泥椎体成形治疗胸腰椎转移瘤的临床疗效。
方法:纳入2012年6月至2017年10月武汉市第五医院收治的恶性肿瘤脊柱骨转移患者101例,年龄 52-87岁,采取随机分配的方法分2组进行骨水泥椎体成形治疗,观察组(n=49,103椎)应用Confidence 高黏度骨水泥,对照组(n=52,107椎)应用贺利氏低黏度骨水泥。治疗后48 h内影像学观察骨水泥渗漏情况;治疗前、治疗后48 h及治疗末次随访时,对比两组疼痛、临床功能与病椎前缘高度、椎体后凸角变化;统计邻近椎体骨折情况。研究通过武汉市第五医院伦理委员会审核批准。
结果与结论:①两组治疗后的疼痛情况、临床功能均较治疗前明显改善(P < 0.05),治疗后相同时间点两组间疼痛情况、临床功能比较差异无显著性意义(P > 0.05);②两组治疗后的病椎前缘高度、椎体后凸角均较治疗前明显改善(P < 0.05),观察组治疗后不同时间点的病椎前缘高度、椎体后凸角改善程度优于对照组(P < 0.05);③观察组骨水泥渗漏率低于对照组(16.50%,22.43%,P < 0.05),随访期复查无邻近椎体再发骨折、无肺栓塞等严重并发症;④结果表明,高、低黏度骨水泥椎体成形治疗胸腰椎转移瘤均可缓解患者疼痛、改善患者生活质量,临床疗效确切、安全性高,其中高黏度骨水泥椎体成形能够更好地恢复椎体前缘高度、降低椎体后凸角、降低骨水泥渗漏风险。

Abstract:

BACKGROUND: Complications such as bone cement leakage are more common in percutaneous vertebroplasty. The choice of different filling materials has become an important factor affecting the surgical outcome.
OBJECTIVE: To investigate the clinical efficacy of percutaneous vertebroplasty with different viscosities of bone cement for treatment of thoracolumbar metastases.
METHODS: A total of 101 patients with bone metastases of malignant tumors, aged 52-87 years, who were admitted during June 2012 to October 2017 by Fifth Hospital in Wuhan, China were randomly assigned to undergo percutaneous vertebroplasty with Confidence high-viscosity bone cement (observation group, n=49, 103 vertebrae) or Heraeus low-viscosity bone cement (control group, n=52, 107 vertebrae). Within 48 hours after surgery, bone cement leakage was observed by imaging examination. The pain, clinical function and the height of the anterior border of the vertebral body as well as the kyphosis of the vertebral body were compared before surgery, 48 hours after surgery, and at the last follow-up. Adjacent vertebral fractures were statistically analyzed. This study was approved by the Ethics Committee of the Fifth Hospital in Wuhan.
RESULTS AND CONCLUSION: After surgery, the pain and clinical function of patients in the two groups were significantly improved compared with those before surgery (P < 0.05). There was no significant difference in pain and clinical function between the two groups at the same time point after surgery (P > 0.05). The height of the anterior border of the vertebral body and the degree of kyphosis of the vertebral body were significantly increased after surgery (P < 0.05). At different time points after surgery, the height of the anterior border of the vertebral body and the degree of kyphosis of the vertebral body were more obviously increased in the experimental group than in the control group (P < 0.05). Bone cement leakage rate in the observation group was significantly lower than that in the control group (16.50% vs. 22.43%, P < 0.05). There were no serious complications, such as recurrent fracture of adjacent vertebral bodies and pulmonary embolism, during the follow up period. These results suggest that high- and low-viscosity bone cement percutaneous vertebroplasty for treatment of thoracolumbar metastases can alleviate pain and improve quality of life with exact clinical efficacy and high safety. High-viscosity bone cement percutaneous vertebroplasty better recovers the height of the anterior border of the vertebral body, reduces the Cobb angles of kyphosis of the vertebral body, and lowers the risk of bone cement leakage than low-viscosity bone cement percutaneous vertesroplasty.

Key words: high-viscosity bone cement, low-viscosity bone cement, vertebroplasty, spine, metastases, pain, leakage, clinical function, height of the anterior border of the vertebral body, degree of kyphosis
