概括

在初级全关节整形术 (THA) 中,用酸 (HA) 涂层的酸体杯显著减少了放射性线条,与非HA涂层杯相比. 然而,在患者结局或修订率上没有发现显著差异,这表明HA涂层杯可能在减少放射性光度方面具有好处.

科学领域:

整形外科手术整形外科手术
生物材料科学是生物材料的科学.
医疗器械工程医疗器械工程

背景情况:

在初级全关节整形术 (THA) 中,无固定是标准的,多孔和酸 (HA) 涂层的植入物是最常见的.
临床前数据表明,HA涂层增强了仅在多孔表面上的植入物固定和稳定性,但临床采用不一致.
有限的元分析存在,比较HA涂层与非HA涂层的形体杯.

研究的目的:

为了比较HA涂层与非HA涂层乙体杯在初级THA中的有效性.
评估HA涂层对修订率,骨解,放射性线条和患者报告结果的影响.
为了确定HA涂层杯是否在THA中提供优越的临床结果.

主要方法:

进行了随机对照试验 (RCT) 的系统审查和元分析.
在Medline,Embase和Cochrane图书馆进行了搜索,直到2024年11月.
评估的结果包括哈里斯部分数 (HHS),骨形成,放射性线条,磨损率,无菌松动修订和异型骨化.

主要成果:

用HA涂层的乙体杯与明显较少的放射性线条有关 (P < 0.00001).
在HA涂层和非HA涂层杯之间没有观察到关于HHS (P = 0.20),内骨骨形成 (P = 0.23),线性磨损率 (P = 0.44),无菌松动 (P = 0.29) 或异型骨化 (P = 0.71) 的修订方面的显著差异.

结论:

在初级THA中,HA涂层的acetabular杯显示了与非HA涂层杯相比,放射性线条的显著减少.
在患者报告的结果,骨形成,磨损或修订率方面,没有发现HA涂层杯子的显著优势.
这些发现表明,由于辐射光度的减少,在初级THA中偏好HA涂层的乙体杯.

Polyprotic Acids

Polyprotic Acids

Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO3, and HCN that contain one ionizable hydrogen atom in each molecule are called monoprotic acids. Their reactions with water are:

Solution Composition During Acid/Base Titrations

Solution Composition During Acid/Base Titrations

The titration of a weak acid with a strong base results in the formation of water and the conjugate base of the acid. For instance, titrating acetic acid with sodium hydroxide leads to the formation of water and sodium acetate. A solution of acetic acid and sodium acetate constitutes a buffer whose relative concentration at different stages of the titration is indicated by the α values, which represent percentages of the weak acid and its conjugate base.
The α0 and α1 values...

Sample Preparation for Analysis: Advanced Techniques

Sample Preparation for Analysis: Advanced Techniques

Accurate analysis of complex samples often requires advanced preparation techniques to achieve reliable and reproducible results. Samples containing inorganic or organic materials can be challenging to dissolve or decompose effectively. Standard sample preparation methods include acid digestion, fusion, dry ashing, and wet digestion.
Acid digestion with strong acids is commonly used to dissolve inorganic materials that are insoluble (do not dissolve) in water. This method can be useful for...
