The study by Gomez et al., "The Fate of Spacers in the Treatment of Periprosthetic Joint Infection," evaluates the clinical course and success rate of treatment of periprosthetic joint infection with two-stage revision with spacer placement in the interim period. The current review critically analyzes the findings of this study and examines how these findings may influence patient care in the field of hip and knee replacement. Gomez et al. report sobering results of two-stage revision with spacer placement for periprosthetic joint infection. Nearly 20% of patients in their study who had a spacer placed never went on to get a new prosthesis and nearly 20% of those who did get a new prosthesis ultimately failed treatment. The authors reported a 7.5% mortality rate in the interstage period after resection arthroplasty. This study provides valuable information for counseling patients about the outcomes of treatment using spacers for infection after total joint arthroplasty. The results of this study also highlight the need for future investigation into better treatments for periprosthetic joint infections.

Gomez 等人的研究 "间隔物在假体周围关节感染治疗中的命运 "评估了假体周围关节感染治疗的临床过程和成功率，该治疗采用两阶段翻修，并在中期放置间隔物。本综述对这项研究的结果进行了批判性分析，并探讨了这些结果会如何影响髋关节和膝关节置换领域的患者护理。戈麦斯（Gomez）等人报告了因假体周围关节感染而进行两阶段翻修并置入垫片的令人沮丧的结果。在他们的研究中，近20%的植入间隔器的患者没有继续植入新假体，而在植入新假体的患者中，近20%最终治疗失败。作者报告称，在切除关节成形术后的间歇期，死亡率为 7.5%。这项研究为患者提供了宝贵的信息，帮助他们了解使用间隔器治疗全关节成形术后感染的结果。这项研究的结果还强调了未来研究更好的假体周围关节感染治疗方法的必要性。

Background: Modularity in total hip arthroplasty has been used for decades with great success, but new findings regarding corrosion artifacts have caused a resurgence in tapered junction research. Mechanically assisted crevice corrosion (MACC) is thought to be the mechanism by which corrosive attack occurs. Myriad multi-factorial variables are known to influence the susceptibility of a modular taper junction to MACC. Some of these variables are design and manufacture related and others can be controlled by the surgeon.

Questions/purposes: This study was performed to assess a 22-year retrieval database to determine if correlations exist between severity of corrosion artifacts and head size, time in vivo, head offset, or head material. Secondarily, the agreement of visual and semi-quantitative scoring methods was assessed using the retrieved components.

Methods: A total of 210 femoral head tapers were scored and heads receiving high scores were measured to quantify material loss due to MACC.

Results: Increased head size and increased time in vivo did not correlate to higher corrosion scores. Contrarily, there were differences in corrosion scores based on femoral head offset and material. Deviations away from a neutral offset (where neutral is defined as the alignment of femoral head center and stem taper gage point) resulted in higher scores. Cobalt-chromium-molybdenum heads were associated with higher corrosion scores and higher material loss as compared to oxidized zirconium heads.

Conclusion: Reducing the moment arm at the head-neck junction and choosing a more inert material appears to provide greater resistance to corrosion.

背景：几十年来，全髋关节置换术中的模块化应用取得了巨大成功，但有关腐蚀伪影的新发现使锥形接合处的研究再次兴起。机械辅助缝隙腐蚀（MACC）被认为是发生腐蚀性侵蚀的机制。众所周知，无数的多因素变量会影响模块化锥形接合处对 MACC 的敏感性。其中一些变量与设计和制造有关，另一些变量则可由外科医生控制：这项研究旨在评估一个长达 22 年的检索数据库，以确定腐蚀伪影的严重程度与头部大小、体内时间、头部偏移或头部材料之间是否存在相关性。其次，使用检索到的部件评估视觉和半定量评分方法的一致性：方法：共对 210 个股骨头锥度进行了评分，并对获得高分的股骨头进行了测量，以量化澳门美高梅国际娱乐平台造成的材料损失：结果：股骨头尺寸的增大和在体内时间的延长与较高的腐蚀评分无关。相反，根据股骨头偏移和材料的不同，腐蚀评分也存在差异。偏离中性偏移（中性定义为股骨头中心与柄锥度测量点对齐）会导致更高的评分。与氧化锆头相比，钴铬钼头的腐蚀评分更高，材料损耗也更大：结论：减少头颈部连接处的力矩臂并选择惰性更强的材料似乎能提供更强的抗腐蚀能力。
