概括
在腰部融合后确定了子沉降 (CS) 风险因素. 高骨质评分 (VBQ),低霍恩斯菲尔德单位 (HU),增加圆盘高度和末板破坏预测CS,VBQ可能会超过HU.
科学领域:
- 脊柱外科手术 脊柱外科手术
- 整形外科 整形外科 整形外科
- 神经外科 神经外科
背景情况:
- 子沉降 (CS) 是腰椎间体融合后的一个并发症.
- 识别风险因素和准确的评估方法对于防止CS至关重要.
- 单侧双门内镜腰椎间体融合 (ULIF) 和横腰椎间体融合 (TLIF) 是常见的外科手术技术.
研究的目的:
- 在单段TLIF和ULIF之后,确定子沉降 (CS) 的风险因素.
- 为了比较基于MRI的脊椎骨质量 (VBQ) 和基于CT的霍恩斯菲尔德单位 (HU) 对CS的预测性能.
- 评估 CS 中即时末板破坏 (IED) 和术后后盘高度 (PPDH) 的作用.
主要方法:
- 追溯分析226名接受ULIF/TLIF治疗的患者的腰椎椎间盘或脊柱狭窄.
- 在CT扫描中,CS被定义为子迁移>2毫米进入脊椎体.
- 使用T1加权MRI评估VBQ;用CT评估IED;用CT扫描测量HU值.
主要成果:
- 后勤回归确定了增加的PPDH,更高的VBQ得分,更低的HU值和IED作为CS的重要风险因素.
- 在预测CS时,VBQ分数的曲线下的面积 (AUC) 比HU值高.
- 与TLIF组相比,ULIF组的CS发生率较低.
结论:
- 高的VBQ分数,低的HU值,增加的PPDH和IED与CS的更高风险有关.
- 无论是VBQ还是HU都是CS的有价值的预测指标,VBQ显示出潜在的优异预测性能.
- 与TLIF相比,ULIF可能与CS的发病率较低有关.

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
