概括
成年脊柱形手术患者的T1斜率高 (≥40°) 经历了初始对齐改善,随后明显恶化. 在这个群体中观察到更高的近端结节形率.
科学领域:
- 脊柱外科手术 脊柱外科手术
- 成年人脊柱形 (ASD) 是一个疾病.
- 放射线图对齐情况
背景情况:
- 在成年脊柱形 (ASD) 手术中,对 Sagittal 对齐的纠正至关重要.
- T1斜率 (TS) 是评估整个脊柱对齐的一个关键参数.
- 升高的TS通常与胸脊和椎脊椎形相关.
研究的目的:
- 为了比较ASD手术前后的脊柱对齐变化.
- 分析手术前T1斜率 (TS) ≥40°和<40°的患者之间的差异.
主要方法:
- 对ASD患者 (年龄≥40岁) 进行脊柱正手术 (2010-2019年) 的回顾性分析,随访时间≥5年.
- 患者分为高TS组 (TS ≥40°) 和低TS组 (TS <40°).
- 在多个时间点评估放射性参数和患者报告的结果措施 (PROMs).
主要成果:
- 高TS组 (n=57) 与低TS组 (n=161) 相比,表现出较高的上部仪器脊椎水平.
- 两组都在手术后改善了斜腰垂直轴 (SVA),但H组在5年后SVA更高.
- 组H表现出增加的胸部 (TK) 和恶化C2-7SVA,近端结节 (PJK) 的发病率更高.
结论:
- 患有TS≥40°的ASD患者经历了最初的对齐效果,随后在5年后出现了非融合细分的恶化.
- 尽管有相似的PROM,但高TS组显示PJK增加,需要谨慎监测.
- 手术前的T1斜率是影响ASD手术中长期的斜面对齐结果的关键因素.

General Structure of a Vertebra
6.1K
A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous...

Mortar Joint Deterioration in Masonry
345
Mortar joint deterioration is a significant concern in masonry structures, with water accumulation in the joints leading to damage from freeze-thaw cycles. The repeated expansion of water during freezing and its melting during thawing develop and propagate cracks in the masonry joints. Eventually, this leads to the spalling of mortar from the joints, loosening masonry units and weakening the structure. The deteriorated mortar joints are also vulnerable to moisture intrusion into the walls.

5-Number Summary
5.5K
In a dataset, the 5-number summary includes the minimum data value, the data value of the first quartile, the median data value or data value of the second quartile, the data value of the third quartile, and the maximum data value. These 5 data values can be visualized as a box and whisker plot.
In a box plot, the minimum and maximum data values represent the lower and upper whiskers in the graph, and the median is designated as the center of the box in the chart. The first quartile and third...

Design Example: Alignment of a Road Line Using GIS
340
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

Aligning actions are communicative strategies individuals employ to maintain social harmony and preserve personal identity in the face of potential disruptions to social norms. These actions are particularly important in managing social impressions when one's behavior might be seen as inappropriate, incompetent, or morally questionable.Types of Aligning ActionsThe three principal types of aligning actions are disclaimers, accounts, and apologies.DisclaimersDisclaimers are preventive; they are...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists
626
5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...
