摘要 背景：将经皮椎体后凸成形通过球囊加压扩张在椎体内形成周围有相对致密松质骨的空腔,可有效降低骨水泥渗漏率,同时扩张的球囊有助于塌陷椎体的复位,矫正脊柱后凸畸形。 目的：回顾性分析手法复位后将经皮椎体后凸成形注入骨水泥治疗骨质疏松性椎体压缩骨折渗漏情况及对椎体高度恢复的影响。 方法：选择2008-02/2010-06华北石油总医院骨科行经皮椎体后凸成形治疗骨质疏松性椎体压缩骨折患者31例,41椎体。平均年龄69(53~82)岁。并于术前手法按压使腰部过伸复位。观察患者术后疼痛缓解、椎体高度恢复以及骨水泥渗漏情况。 结果与结论: 所有患者术后随访8~13(11.0±1.6)个月。患者视觉模拟疼痛评分由术前6.7±1.9下降至术后1.3±1.2,差异有显著性意义(P < 0.05)。椎体高度由术前(15.7±5.2) mm恢复至(20.2±4.5) mm,椎体高度显著恢复(P < 0.05)。发生骨水泥渗漏3例,均无明显临床症状。说明术前手法复位后经皮椎体后凸成形将骨水泥注入骨质疏松性椎体压缩骨折可以显著恢复椎体高度,止痛效果良好且无严重渗漏发生。 关键词：经皮椎体后凸成形;骨质疏松;骨质疏松性椎体压缩骨折;骨水泥;生物材料 doi:10.3969/j.issn.1673-8225.2010.42.038     

注射型磷酸钙人工骨椎体后凸成形固化治疗骨质疏松性胸腰椎压缩骨折

背景：椎体后凸成形目前常用的注射型聚甲基丙烯酸甲酯骨水泥椎体增强剂可达到增加椎体强度、稳定椎体、止痛的目的,但其组织相容性差,无生物降解性,容易造成使临近椎间盘或椎体发生变性、甚至骨折。 目的：观察注射型磷酸钙人工骨椎体后凸成形固化治疗骨质疏松性椎体压缩骨折的效果。 方法：选择2007-12/2010-06哈尔滨医科大学附属第四医院骨外科收治的骨质疏松性胸腰椎压缩性骨折患者20例,均采用经双侧椎弓根球囊扩张注射型磷酸钙人工骨行椎体后凸成形固化治疗。手术前后行疼痛目测类比评分,胸(腰)椎正侧位X射线片及椎体前缘高度、Cobb角检测。 结果与结论：术后病椎前缘椎体平均高度较术前平均高度恢复(3.38±1.44) mm (P < 0.05)。术后Cobb角较术前平均恢复(7.63±2.52)° (P < 0.05),后凸矫正率为(38.90±11.28)%。术后3d及3周目测类比评分均较术前明显降低(P < 0.01)。说明经双侧椎弓根球囊扩张注射型磷酸钙人工骨行椎体后凸成形可以有效增加椎体强度、稳定椎体、明显缓解患者疼痛,是治疗骨质疏松性胸腰椎压缩骨折的有效方法。     

多椎体病变一次性经皮穿刺注入骨水泥椎体成形31例

背景：老年性骨质疏松、骨髓瘤和转移性肿瘤时往往发生多个椎体的病变和压缩,但文献对多发性椎体病变的成型治疗报道较少。 目的：探讨多椎体胸腰椎病变一次性经皮穿刺注入骨水泥椎体成形的治疗效果和相关材料与宿主反应的注意事项。 设计、时间及地点：观察性试验,病例来自2004-11/2008-10十堰市太和医院脊柱外科、康复科和肿瘤科等。 对象：选择十堰市太和医院脊柱外科、康复科、肿瘤科等收治的老年性骨质疏松合并压缩性骨折、多发性骨髓瘤和溶骨性转移性肿瘤患者31例,男14例,女17例;年龄56~82岁。 方法：对31例2个以上椎体异常的患者进行一次性经皮穿刺椎体成形术。局麻下先后采用椎弓根入路穿刺病变椎体,在严密监测下依次向各病变椎体内加压注射骨水泥,术后观察椎体内骨水泥注入情况和患者的反应,术后1周评价治疗效果。 主要观察指标：一次性椎体成形的数目,椎体穿刺成功率,骨水泥注射量、椎体内骨水泥分布情况,骨水泥向椎旁软组织和静脉泄漏情况,疼痛缓解及有无并发症发生。 结果：共进行33次75个椎体的成型治疗,最少1次2个椎体,最多1次5个椎体,平均1次进行2.27个椎体成型;各椎体内骨水泥注射剂量4~12 mL,平均7.5 mL,椎体内骨水泥均匀充填49个,部分充填椎体者26个;注入骨水泥中未发生明显并发症,所有患者术后局部疼痛缓解,其中明显缓解或消失者20例,部分缓解者11例。 结论：经皮穿刺注入骨水泥椎体成形是治疗椎体病变有效而安全的方法,多椎体一次性成形治疗要求合理的骨水泥注射方法和剂量以及严密的治疗过程中的监测。     

注入骨水泥椎体成形与非手术治疗骨质疏松性椎体压缩骨折的Meta分析

背景：注入骨水泥椎体成形或称经皮椎体成形术作为治疗骨质疏松性椎体压缩骨折的微创技术,一些病例报道及非随机对照研究揭示了椎体成形对骨质疏松性椎体压缩骨折引起的疼痛有效。然而,这些研究主要基于回顾性的病例分析,缺乏高质量的随机对照研究。 目的：通过系统评价Meta分析的方法对椎体成形术与非手术治疗骨质疏松性椎体压缩骨折的疗效进行评价。 方法：计算机检索Cochrane Library(2010年第4期) 、PubMed (1966/2010-11)、EMBASE(1974/2010-11)、CBM (1978/2010-11)、CNKI(1994/2010-11)、和万方数据库(1997/2010-11)。纳入椎体成形术与非手术治疗骨质疏松性椎体压缩骨折的随机对照试验,按照Cochrane Handbook 5.0 进行严格的质量评估,采用RevMan 5.0.1软件进行Meta分析。 结果与结论: 共纳入4个随机对照试验,共445例患者。Meta分析结果显示,与保守治疗比较,随访1,4,24,48 周时椎体成形术在缓解疼痛方面更明显,在新发骨折发生方面,两种治疗方法没有差别;与安慰剂相比,随访4周时椎体成形术在缓解疼痛、提高腰部功能活动及改善生活质量方面并无明显优势。受系统评价纳入研究数量以及质量的限制,上述结论尚需要更多高质量的随机对照试验进一步验证。

经皮椎体成形过程中骨水泥注入及其并发症

经皮椎体成形以其创伤小、操作方式简单、疗效快且确切、安全性高、适应证广等优点,很快受到广泛关注和接受,尤其是在治疗椎体压缩性骨折方面取得了明显的疗效。聚甲基丙烯酸甲酯是目前最常用的填充物;单侧注射和双侧注射疗效没有明显差别;应用对比剂及掌握合适的骨水泥黏稠度可以减少骨水泥的渗漏率;成形前腰部垫枕自身复位可以恢复椎体的高度,避免采用操作复杂及价格昂贵的球囊后凸成形及骨膨胀椎体后凸成形;进行经皮椎体成形时应该配合应用抗骨质疏松药物,以减少椎体再骨折的发生。     

单侧穿刺经皮椎体注入骨水泥后凸成形治疗多椎体骨质疏松性压缩骨折

背景：经皮椎体成形和经皮椎体后凸成形是一种治疗骨质疏松症所致椎体压缩性骨折的新方法,目前已经在各大医院广泛开展,但是在临床上很多病例有多个椎体的骨折,采用经典的手术方法操作次数多,增加手术风险,射线暴露量大,医疗费用高。 目的：观察单侧穿刺经皮椎体后凸成形治疗老年多椎体骨质疏松压缩骨折的疗效。 方法：选择2007-06/2009-06巢湖市第一人民医院骨二科和皖南医学院附属弋矶山医院骨一科收治的多椎体骨质疏松压缩骨折患者12例(29椎),根据治疗前MRI信号改变判断疼痛性椎体并进行选择性单侧穿刺球囊扩张后凸成形的治疗。根据目测类比评分评价手术前后疼痛变化,观察治疗后症状改善、骨折复位情况及有无并发症发生。 结果与结论：12例穿刺均顺利完成,48 h内疼痛缓解,平均随访14个月。治疗后目测类比评分较治疗前降低(P < 0.01)。椎体前缘、中部、后缘平均高度治疗前低于治疗后,至末次随访椎体复位后前缘、中部、后缘平均高度未见明显丢失(P > 0.05)。治疗前穿刺侧与对侧椎体高度差距有显著性意义(P < 0.01),治疗后两侧差距无显著性意义(P > 0.05)。治疗前后同侧相比差异均有显著性意义(P < 0.01)。提示对多椎体压缩骨折采用选择性单侧穿刺后凸成形治疗,临床效果满意,能够缩短治疗时间、减少并发症、射线暴露和治疗费用,适于老年多椎体骨质疏松压缩骨折的治疗。 关键词：骨质疏松;脊柱;压缩骨折;后凸成形;骨水泥 doi:10.3969/j.issn.1673-8225.2010.25.025

A meta-analysis of balloon kyphoplasty compared to percutaneous vertebroplasty for treating osteoporotic vertebral compression fractures

A meta-analysis was conducted to assess the safety and efficacy of balloon kyphoplasty (KP) compared to percutaneous vertebroplasty (VP) in the treatment of osteoporotic vertebral compression fractures (OVCF). Ten studies, encompassing 783 patients, met the inclusion criteria. Overall, the results of the meta-analysis indicated that there were significant differences between the two groups in the long-term kyphosis angle (mean difference [MD] = –2.64, 95% confidence interval [CI] = –4.66 to –0.61; p = 0.01), the anterior height of the vertebral body (MD = 3.67, 95% CI = 1.40 to 5.94; p = 0.002), and the cement leakage rates (risk ratio [RR] = 0.70, 95% CI = 0.52 to 0.95; p = 0.02). However, there were no significant differences in the short-term visual analog scale (VAS) scores (MD = –0.57, 95% CI –1.33 to 0.20; p = 0.15), the long-term VAS scores (MD = –0.99, 95% CI = –2.29 to 0.31; p = 0.14), the short-term Oswestry Disability Index (ODI) scores (MD = –6.54, 95% CI = –14.57 to 1.48; p = 0.11), the long-term ODI scores (MD = –2.01, 95% CI = –11.75 to 7.73; p = 0.69), the operation time (MD = 4.47, 95% CI = –0.22 to 9.17; p = 0.06), the short-term kyphosis angle (MD = –2.25, 95% CI = –5.14 to 0.65; p = 0.13), or the adjacent-level fracture rates (RR = 1.52, 95% CI = 0.76 to 3.03; p = 0.24). This meta-analysis demonstrates that KP and VP are both safe and effective surgical procedures for treating OVCF. Compared with VP, KP can significantly relieve a long-term kyphosis angle, improve the height of the vertebral body, and reduce the incidence of bone cement leakage. However, because of the limitations of this meta-analysis, a large randomized controlled trial is required to confirm our findings.

The technique is safe and can be performed on an outpatient basis utilizing high-resolution fluoroscopy.     

经皮椎体成形和经皮椎体后凸成形治疗国人胸腰椎压缩性骨折疗效及安全性的Meta分析

背景：经皮椎体成形和经皮椎体后凸成形治疗胸腰椎压缩性骨折在国内外均积累了相当多的临床经验,但尚缺乏循证医学方面的依据。目的：采用Meta分析评价经皮椎体成形和经皮椎体后凸成形治疗胸腰椎压缩性骨折的疗效以及安全性。方法：搜集国内应用经皮椎体成形和经皮椎体后凸成形对比治疗胸腰椎压缩性骨折的文献,并追查已纳入文献的参考文献。由至少两位系统评价员做独立文献筛查、质量评价和资料提取,并交叉核对,不同意见请第三者裁决。使用统计软件RevMan 5.0完成Meta分析。结果与结论：经筛选,最后纳入7篇文献进行Meta分析,包括受试患者398例,其基线情况一致,具有可比性。5篇文献的随访时间为6周,2篇为4周。结果提示,经皮椎体成形和经皮椎体后凸成形均是治疗国人胸腰椎压缩性骨折的有效方法,且在改善目测类比评分方面差异无显著性意义(P > 0.05);在改善Cobb角及治疗后骨水泥渗漏发生率方面,经皮椎体后凸成形均优于经皮椎体成形(P < 0.001,P=0.05)。因纳入文献和样本量有限,建议进行大样本、长期随访的高质量临床试验,提供更佳循证证据。     

Comparison of unilateral and bilateral puncture percutaneous kyphoplasty in the treatment of osteoporotic vertebral compression fractures

Objectives:To compare the clinical efficacy of unilateral and bilateral puncture PKP in the treatment of OVCFs and explored whether there is a difference in the efficacy of unilateral and bilateral puncture PKP after surgery.Methods:A total of 98 patients with OVCFs treated by PKP from August 2016 to June 2018 were selected. There were 62 cases in the unilateral puncture group and 36 cases in the bilateral puncture group. The operation time, the amount of bone cement injection, the height of the anterior edge of the vertebral body and the visual analog scale (Visual Analog Scale, VAS) scores before and after the operation were analyzed, and whether the differences between the 2 groups were statistically significant was analyzed.Results:All patients were followed up completely. The operation time and the number of X-ray fluoroscopies of the unilateral puncture group were significantly reduced compared to those of the bilateral group, and the difference was statistically significant (p<0.05). In terms of the bone cement injection volume, the average injection volume of the bilateral group was greater than that of the unilateral group, and the difference was statistically significant (p<0.05); the postoperative VAS scores of the 2 groups of patients were significantly improved, and the difference was statistically significant compared with that before surgery (p<0.05) but that of the unilateral group was not statistically significant compared with that of the bilateral group (p>0.05). The height of the anterior edge of the vertebral body in both groups was significantly improved compared with that before the operation, and the difference was statistically significant (p<0.05).Conclusion:Unilateral and bilateral puncture PKP can achieve good clinical efficacy in the treatment of osteoporotic vertebral compression fractures, but unilateral PKP has the advantages of short operation time and low X-ray exposure.

Osteoporosis (OP) is caused by a decrease in bone mass for a variety of reasons, especially a decrease in the amount of cancellous bone in the vertebral body and damage to the microstructure of bone tissue, bone mineral composition and bone matrix per unit volume. Osteoporosis is one of the diseases with high morbidity and mortality in the world and has become an important disease that endangers the health of middle-aged and elderly people.¹ Osteoporotic vertebral compression fractures (OVCFs) are one of the major complications of osteoporosis, which often cause stubborn waist and back aches. Severe thoracolumbar osteoporotic vertebral body compression fractures may lead to cardiopulmonary and other multisystem dysfunctions, seriously affecting the patient’s quality of life.²For the treatment of OVCFs, the current recommendations are conservative treatment and surgical treatment. Conservative treatment may cause various complications due to long-term bed rest, including bedsores, delayed fracture healing, deformity healing or nonunion, respiratory and urinary tract infections, and lower extremity venous thrombosis, which can threaten the life of the patient.^3,4 Therefore, patients with OVCFs who have early out-of-bed activity requirements and surgical indications are more likely to undergo surgical treatment.The traditional surgical treatment for OVCFs is posterior laminectomy and decompression pedicle screw internal fixation, but due to the higher degree of osteoporosis in older patients, the long-term screw internal fixation effect is poor, and surgical trauma has a greater impact on patients; thus, the long-term efficacy is not ideal.⁵ In recent years, with the improvement of minimally invasive spine technology, percutaneous vertebralplasty (PVP) and percutaneous balloon dilatation kyphoplasty (Percutaneous kyphoplasty, PKP) have achieved satisfactory results in the treatment of OVCF. Compared with PVP, PKP uses a balloon or other expansion system to expand the compressed vertebral body to form a relatively low-pressure vertebral body space, followed by low-pressure injection of bone cement, which can better correct kyphosis and reduce the penetration of bone cement leakage.^6,7The PKP surgical puncture consists of a bilateral pedicle approach or a unilateral pedicle approach. While the advantages of the transdermal bilateral pedicle approach include better diffusion of bone cement and reduced risk of puncture, there are shortcomings, such as long operation time, large radiation exposure and high hospitalization costs.⁸ At present, there is no unified conclusion as to which PKP approach is better for use to treat OVCFs. Therefore, it is of great clinical significance to clarify the difference between unilateral and bilateral PKP in the treatment of OVCFs.The OVCFs are one of the common diseases that cause lumbago and kyphosis in the elderly. At present, PKP is one of the common methods for the treatment of OVCFs. Bilateral puncture of the pedicle approach is the classic operation method of PKP, but some scholars believe that unilateral puncture bone cement injection can achieve the same surgical effect. This record-based case–control study retrospectively analyzed patients with OVCFs treated in our hospital from August 2016 to June 2018, performed an in-depth analysis and comparison of the unilateral and bilateral PKP treatment of OVCFs, and provided a reference for the clinical approach to PKP treatment of OVCFs.
