概括
金属敏感反应并不是导致金属对金属关节置换术失败的主要原因. 大量的液体和高水平预测了这些反应,但许多痛苦的病例没有明确的原因.
科学领域:
- 整形外科手术 整形外科手术
- 生物材料科学 生物材料科学
- 毒理学 毒理学 毒理学
背景情况:
- 金属对金属 (MoM) 关节整形术 (THA) 可能由于金属敏感反应 (MSR) 而失败.
- 然而,MSR可能不是所有痛苦的MoM THA病例中失败的主要原因.
- 本研究研究了修订后的MoM THAs的各种故障模式.
研究的目的:
- 为了确定疼痛修订的MoM THAs的失败病因.
- 分析经过修订后的手术指示和临床结果.
- 在MoM THA故障中识别金属敏感反应的预测因子.
主要方法:
- 90个连续修订的MoM THAs的审查.
- 术前评估包括炎症标志物,金属离子水平,成像 (MRI) 和突液分析.
- 评估手术组织病理学和临床结果后修订.
主要成果:
- 金属敏感反应 (MSRs) 占MoM失败的36%;64%是由于感染,松和机械问题等非MSR病因.
- 大量的周关节液体收集 (OR 19.2) 和高 (Co) 水平对MSR的高度预测.
- 18%的痛苦的MoM THAs没有可识别的原因,69%的人经历了修订后的持续疼痛.
结论:
- 大多数修订的MoM THA由于MSR以外的原因而失败.
- 周关节液体收集和高水平是MSR的强有力的指标.
- 无法解释的痛苦的MoM THA带来了重大挑战,往往导致复查后持续的疼痛.

02:32Bonding in Metals
Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.
01:21Fatigue
Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...
01:29Imperfections in Crystal Structure: Non-Stoichiometric Defects
Non-stoichiometric defects refer to a type of defect in the crystal structure of a compound where the ratio of its constituent elements deviates from the ideal stoichiometric ratio. There are two main types of non-stoichiometric defects: metal excess defects and metal deficiency defects.Metal excess defects occur when there is a slight surplus of metal ions than what is required by the stoichiometric ratio of the compound. For example, heating a sodium chloride crystal in sodium vapor results...
