The bibliometric analysis had been conducted to understand the active authors, organizations, journals, and countries involved in the research domain of “Allergy of steel -implants”. All published articles related to “Allergy of steel-implants” from “Scopus”, were analyzed using the VOS viewer to develop analysis tables and visualization maps. This article had set the objective to consolidate the scientific literature regarding “Allergy of steel- implants” and also to find out the trends related to the same. The most active journals in this research domain were the Contact Dermatitis, Injury, and Journal of Paediatric Surgery. The most active country was the United States of America. The leading organization engaged in the research regarding allergy of steel-implants were University Hospital in Munich and Ludwig- Maximilian University of Germany. The most active authors who had made valuable contributions related to the allergy of steel implants were Summer B. and Thomas P.

Introduction An engineered medical device to replace a missing or damaged biological structure is known as an implant. Different types of metals and materials are used to create implants and the most popularly used metals and alloys for bio-implants are stainless steel, cobalt-chromium alloy, and Titanium [1]. Various types of implants had been used in modern medicine and include sensory implants, neurological implants, cardiovascular implants, orthopedic implants, contraceptive implants, and cosmetic implants. Stainless steel is used for diversified implanting devices allergy and corrosion are serious challenges associated with stainless steel implants [2]–[5]. The allergy to metal implants is a serious issue to be addressed. Safety of material used is an important determinant while choosing implants and Stainless steel is a comparatively s safe metal used for implants. Material engineering and surface engineering can play a significant role in improving safety and reducing allergies associated with steel implants. Stainless steel is often considered a safe metal for hip implants in comparison with Nickel [6]. Similarly, the blood nickel content can be reduced and serious complications like hypernickelemia can be avoided [7]. Stainless steel is not having high-class anticorrosive properties [8] and there are cases of implant failure due to corrosion of stainless steel [9]. Bacterial infection of implants can be a cause for allergy and failure of steel implants. Bacterial infection of steel implants can be mitigated by silver coating on the implants [10]. The future research can be on various research niches like surface coating, anti-bacterial properties, and corrosion-resistant technologies associated with stainless steel implants. The reduced level of corrosion can help in less wear and less amount metal content in the blood. This bibliometric analysis will be a useful platform for future researchers by realizing the top researchers, organizations, and countries involved in research regarding bio-implants. This article is arranged into four sections. The first section is the introduction, followed by the discussion of the methodology by which the research was conducted. The third section deals with results and discussion. The fourth section deals with the conclusion. The following research objectives and research questions were framed for conducting bibliometric analysis systematically. 1.1 Research Objectives a) To consolidate the literature regarding allergy of steel-implants b) To find out the trends related to research in allergy of steel-implants 1.2 Research Questions a) Who are the active researchers working on the allergy of steel-implants? b) Which are the main organizations and countries working on the allergy of steel-implants? c) Which are the main journals related to an allergy to steel-implants? 2. Research Methodology Scopus files had been used for this article. For the article selection, the Boolean used was TITLE-ABS-KEY (Allergy Steel-implants) on 01/03/2021. All the tables in this paper were created by using Microsoft Excel and VOS Viewer. Grammarly was used for spelling and grammar checks. Mendeley was used for article review and
