椎体成形术治疗骨质疏松椎体压缩性骨折后新发椎体骨折风险的列线图模型的建立

目的 分析影响椎体成形术治疗骨质疏松性椎体压缩性骨折(osteoporotic vertebral compression fracture, OVCF)后出现新发椎体骨折的相关危险因素,并以此建立预测患者术后出现新发椎体骨折的列线图模型。方法 选取2019年1月至2020年12月间在本医院进行椎体成形术治疗的OVCF患者187例,术后随访1年,根据患者术后是否出现新发椎体骨折分为新发组51例,无新发组136例。应用Logistic回归分析影响患者术后出现新发椎体骨折的相关危险因素。采用R3.6.3软件包绘制预测患者术后出现新发椎体骨折的列线图模型;用校准曲线、ROC曲线判断预测效果。结果 单因素分析结果显示,体重指数(bady mass index, BMI)、骨密度、骨水泥渗漏、长期使用糖皮质激素药物、术后是否规律治疗骨质疏松、术后是否规律锻炼与患者术后出现新发椎体骨折有关(P<0.05)。Logistic回归分析显示,骨密度低(OR=2.861)、长期使用糖皮质激素药物(OR=4.371)是出现新发椎体骨折的独立危险因素(P<0.05);而术后规律治疗骨质疏松(OR=...

Risk factors of developing new symptomatic vertebral compression fractures after percutaneous vertebroplasty in osteoporotic patients

Percutaneous vertebroplasty (PVP) is an efficient procedure to treat pain due to osteoporotic vertebral compression fractures (OVCFs). However, some patient populations experience recurrent vertebral fracture after initial successful procedure. There are a lot of literatures about the effectiveness of this procedure but few concerning the development of recurrent, new compression fracture. This is a retrospective review of all PVPs performed in author’s institution from September 1999 to December 2001 to investigate the factors related to the development of new symptomatic OVCFs after PVPs. A retrospective review of 244 cases of PVP for symptomatic OVCFs at 382 levels was performed. Sociodemographic, clinical, radiologic, and procedural data were analyzed and compared between the two patient groups (control group : no further symptomatic OVCFs after the initial PVP, “new symptomatic fracture” group: with newly developed symptomatic OVCF). Statistical analysis was performed between the variables of the two groups. Survival analysis was performed using the Kaplan–Meier method. Over all, 38 among 244 treated patients (15.6%) had experienced newly developed symptomatic OVCF(s) during the follow up period (mean 52.5 months). Old age and the presence of multiple treated vertebrae at the initial PVP were assessed as a strong parameter for predicting new symptomatic OVCF. With increasing preoperative wedging deformity the risk of developing new symptomatic OVCF decreased. The Kaplan-Meier estimate of the 1 year fracture-free rate was 92.2%. The Kaplan–Meier curve showed that 7.8% of the patients would experience new symptomatic OVCF within 1 year after initial PVP. A preoperative only mild wedge deformity of the fractured vertebra(e) could indicate the increased risk of developing new symptomatic OVCF after vertebroplasty.     

Recollapse of previous vertebral compression fracture after percutaneous vertebroplasty

Summary  This study was undertaken to investigate the incidence rate, characteristics, and predisposing factors associated with recollapse of the same vertebrae after percutaneous vertebroplasty (PVP). Recollapse of the same vertebra after PVP is the one of the complications of the procedure, and the incidence rate in our study was 3.21%. The most important predisposing factor was pre-operative osteonecrosis. Recollapse was not related to trauma. Introduction  PVP using polymethylmethacrylate has become a popular treatment for osteoporotic vertebral compression fracture. Recollapse of the same vertebrae after PVP has rarely been reported. This study was undertaken to investigate the incidence, characteristics, and predisposing factors associated with recollapse of the same vertebrae after PVP. Methods  Eleven patients (seven females and four males; mean age, 69.91 ± 5.49 years), out of a total of 343 patients, developed recollapse of the same vertebra after PVP. The 11 patients who developed recollapse comprised the “recollapse group”, while the remaining 332 patients comprised the “well-maintained group”. Results  Pre-operative magnetic resonance imaging revealed that the incidence of osteonecrosis was significantly higher in the recollapse group than the well-maintained group (p < 0.05). The degree of re-expansion of the compressed vertebral body after PVP was significantly higher in the recollapse group than in the well-maintained group (p < 0.05). Conclusions  The most important predisposing factor for recollapse was pre-operative osteonecrosis. Recollapse was not related to trauma. Osteoporotic vertebral compression fracture with osteonecrosis or pseudoarthrosis has been regarded as a relative indication for PVP; however, the findings of this study suggest that this disease category may be a relative contraindication for PVP.

目的: 探讨经皮椎体成形术(percutaneous vertebroplasty,PVP)和经皮椎体后凸成形术(percutaneous kyphoplasty,PKP)术后再骨折的相关危险因素。方法:回顾性分析2012年6月～2013年8月在苏北人民医院脊柱外科行经皮椎体成形术治疗的骨质疏松性椎体压缩骨折(OVCF)患者177例,依据是否发生再骨折,将患者分为骨折组(28例)和对照组(149例)。对两组患者相关因素进行单因素和Logistic回归分析。结果:177例患者均顺利完成手术,术后随访6-24个月,平均15.5月,发现28例(15.8%)患者发生新发骨折。单因素和Logistic回归分析显示:年龄、既往存在骨折病史、骨密度是患者出现再骨折的危险因素。结论: 高龄、既往存在其他骨折病史和低骨密度是再骨折的危险因素。     

唑来膦酸在骨质疏松性椎体压缩骨折经皮椎体成形术后的临床应用

目的：通过对比研究,观察骨质疏松性椎体压缩骨折的患者在经皮椎体成形术后应用唑来膦酸的临床治疗效果。方法2010年7月至2013年2月,将中山市中医院骨一科240例椎体压缩性骨折行PVP手术治疗的患者随机分成两组,治疗组在术后3日予以静滴唑来膦酸针;对照组单纯予以椎体成形术。两组患者自入院起均予以口服碳酸钙／维生素D3片,600 mg／d。分别于术前1周及术后1月、3月、6月、9月、一年行腰椎骨密度、血清PINP及β－CTX浓度检查,并进行统计分析。结果随访1年,两组患者共240例获得随访,治疗后治疗组患者在VAS评分、腰椎骨密度、血清PINP及β－CTX浓度等的变化与对照组相比均具有显著性差异,且治疗组患者的依从性较好,新发椎体骨折少。结论唑来膦酸治疗骨质疏松性椎体压缩骨折可增加患者椎体骨密度、改善患者疼痛、预防新发椎体骨折、提高患者生活质量,可用于骨质疏松性椎体压缩骨折患者PVP术后的巩固治疗。     

骨质疏松性椎体压缩骨折椎体成形术后非手术椎体再骨折危险因素探讨

骨质疏松性椎体压缩骨折(osteoprosis vertebral compression fracture,OVCF)是老年性及绝经后骨质疏松症患者最常见的严重并发症,骨折患者常有骨性疼痛、椎体高度下降、脊柱后凸畸形等临床表现,严重影响患者生活质量。经皮椎体成形术(percutaneous vertebroplasty,PVP)、经皮椎体后凸成形术(percutaneous kyphoplasty,PKP)及网袋加压椎体成形术(vesselplasty)是治疗OVCF的常用术式,在恢复椎体高度、预防后凸畸形、减轻疼痛症状等方面优势突出。但OVCF患者椎体成形术后存在非手术椎体再发骨折的可能性,在影响手术质量的同时,对患者术后康复、生活质量、经济负担均有较大影响。椎体成形术后非手术椎体再发骨折与骨质疏松进程、初始骨折部位及数量等自身客观因素相关,也与术后椎体高度的过度恢复、骨水泥渗漏、骨水泥过度填充等手术因素密切相关。本文通过查阅近年来关于OVCF患者椎体成形术后非手术椎体再发骨折危险因素及原因文献报道,综述经过统计学方法验证的,具有统计学意义的危险因素,通过患者自身因素、手术因素等方面展开探讨,以期能够为临床降低OVCF患者椎体成形术后再发骨折的发生率提供相关参考。     

Cement leakage in percutaneous vertebroplasty for osteoporotic vertebral compression fractures: identification of risk factors

Background context

Percutaneous vertebroplasty (PVP) is a common treatment modality for painful osteoporotic vertebral compression fractures (OVCFs). The complication rate of PVP is low, but cement leakage occurs in up to 90% of the treated levels. Recent evidence suggests that sequelae of cement leakage may be more common and clinically relevant than previously thought. Preoperative appreciation of risk factors would therefore be helpful but has not been thoroughly investigated.

Purpose

Identification of preoperative risk factors for the occurrence of cement leakage in PVP for painful OVCFs.

Study design

Retrospective assessment of risk factors using multivariate analysis.

Patient sample

Eighty-nine patients treated with PVP for 177 painful OVCFs.

Outcome measure

Occurrence of cement leakage.

Methods

The influence of all known risk factors and other parameters potentially affecting the occurrence of cement leakage was retrospectively assessed using multivariate analysis. Patient age, sex, and spinal deformity index; fracture age, level, type, and semiquantitative severity grade (1–4), the presence of an intravertebral cleft and/or cortical disruption on preoperative magnetic resonance imaging (MRI), and the viscosity of bone cement were included. Cement leakage was assessed on direct postoperative computed tomography scanning of the treated levels. In addition to cement leakage in general, three fundamentally different leakage types (cortical, epidural, and anterior venous), with different possible clinical sequelae, were discerned, and their respective risk factors were assessed.

Results

In 130 of 173 (75.1%) treated OVCFs, cement leakage was detected. Leakage incidence was found to increase approximately linear with advancing severity grade. High fracture semiquantitative severity grade (adjusted per grade relative risk [RR], 1.14; 95% confidence interval [CI], 1.05–1.24; p=.002) and low bone cement viscosity (medium vs. low viscosity: adjusted RR, 0.73; 95% CI, 0.61–0.87; p<.001) were strong risk factors for cement leakage in general. For cortical leakage (in 95% intradiscal leakage), the presence of cortical disruption on MRI (adjusted RR, 1.62; 95% CI, 1.16–2.26; p=.004) and an intravertebral cleft on MRI (adjusted RR, 1.43; 95% CI, 1.07–1.77; p=.017) were identified as additional strong risk factors.

Conclusions

High fracture severity grade and low viscosity of polymethylmethacrylate bone cement are general, strong, and independent risk factors for cement leakage. Using MRI assessment, cortical disruption and the presence of an intravertrebral cleft were identified as additional strong risk factors regarding cortical (intradiscal) cement leakage, thereby potentiating anticipation.

目的比较经皮椎体成形术(PVP)治疗新鲜与陈旧不愈合骨质疏松性椎体压缩骨折(OVCFs)的疗效。方法 544例接受PVP手术患者,按照从受伤到手术时间的间隔将患者分为A组(新鲜骨折,3周,456例)和B组(陈旧骨折不愈合,8~24周,88例)。采用疼痛VAS评分对患者术前、离院时、术后3个月、术后1年进行疗效评价。结果 512例患者获得为期1年的随访,随访率为94.1%,其中A组430例(492处骨折),B组82例(86处骨折)。骨水泥注射剂量:A组为3.2~8.0(5.6±0.05)ml,B组为3.0~7.6(6.0±0.04)ml,差异无统计学意义(P0.05)。骨水泥渗漏率:A组为9.8%(42/430),B组为4.9%(4/82),差异有统计学意义(P0.05)。VAS评分:A组术前为9.2分±0.06分,离院时为2.2分±0.07分,术后3个月时为2.3分±0.06分,术后12个月时为2.5分±0.05分,术后各时段与术前相比差异均有统计学意义(P0.05);B组术前为8.6分±0.05分,离院时为1.0分±0.07分,3个月时为1.1分±0.04分,术后12个月时为1.1分±0.03分,术后各时段与术前相比差异均有统计学意义(P0.05)。两组VAS评分比较:术前差异无统计学意义(P0.05),离院时、术后3个月及术后12个月差异均有统计学意义(P0.05)。结论 PVP通过骨水泥可以将陈旧OVCFs椎体内的假关节牢固固定,不但可以达到解除疼痛的目的,而且显著降低了骨水泥发生严重渗漏的风险,疗效优于新鲜骨折。     

高粘度骨水泥经皮椎体成形术治疗骨质疏松性椎体压缩骨折的疗效分析

目的 :比较高粘度骨水泥经皮椎体成形术(PVP)与低粘度骨水泥经皮椎体后凸成形术(PKP)治疗骨质疏松性椎体压缩骨折(OVCF)的临床疗效及影像学特征,评价高粘度骨水泥PVP治疗OVCFs的临床价值。方法:2015年6月~2016年12月我院收治单节段骨质疏松性椎体压缩骨折患者115例,其中65例行高粘度骨水泥PVP(A组),50例行低粘度骨水泥PKP(B组),两组患者年龄、性别、体重指数(BMI)、骨密度(BMD)均无统计学差异。统计两组患者的手术时间、术中透视次数、骨水泥用量、骨水泥渗漏、骨水泥弥散分布情况、伤椎椎体前缘高度和椎体后凸角(Cobb角)、术前和术后VAS评分及ODI等资料,应用SPSS 20.0进行统计学分析。结果:两组患者术后VAS评分、ODI、伤椎椎体前缘高度及Cobb角均较术前显著性改善(P0.01);两组间骨水泥渗漏率无显著性差异;A组手术时间、术中透视次数均显著性少于B组(P0.05)。A组骨水泥单侧弥散分布、双侧不对称分布、双侧对称分布分别为6例(9.2%)、12例(18.5%)、47例(72.3%),未弥散至终板、单侧终板弥散、双侧终板弥散分别为3例(4.6%)、16例(24.6%)、46例(70.8%);B组骨水泥单侧弥散分布、双侧不对称分布、双侧对称分布分别为33例(66.0%)、7例(14.0%)、10例(20.0%),未弥散至终板、单侧终板弥散、双侧终板弥散分别为17例(34.0%)、22例(44.0%)、11例(22.0%),两组间比较有显著性差异(P0.01)。结论:高粘度骨水泥PVP治疗OVCF可获得良好的短期临床疗效,骨水泥可对称地弥散至椎体前柱两侧以及椎体上下终板,使伤椎均衡强化,有利于减少手术椎体再骨折风险,骨水泥渗漏风险与低粘度骨水泥PKP相当。
