Jamjoom AB, Gahtani AY, Jamjoom JM, Sharab BM, Khogeer YK, Jamjoom OM, Alzahrani MT. Bibliometric Research in Neurosurgery: A Review of the 50 Most Cited Bibliometric Publications in the Neurosurgical Literature. Cureus 2024; 16:e67247. [PMID: 39301345 PMCID: PMC11411117 DOI: 10.7759/cureus.67247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/19/2024] [Indexed: 09/22/2024] Open
Abstract
Bibliometry is a popular research method that is used to explore and analyze large volumes of data in an effort to highlight trends, patterns, and impacts within a specific field. This review aimed at highlighting the characteristics and citation patterns of the high-impact bibliometric research studies that were published in the neurosurgical literature. Using PubMed and Google Scholar, the 50 (52 due to identical citation numbers for the lowest three articles) most cited bibliometric research publications were identified and reviewed. Information relating to the articles' publication and bibliometric features were retrieved. The articles' citation numbers were collected. The median article age and journal impact factor (IF) were eight years and 2.76, respectively. The majority of studies were published in World Neurosurgery and the Journal of Neurosurgery, which were the publishing journals for 18 (35%) and 12 (23%) articles, respectively. Twenty-six (50%) articles were first authored by researchers from the United States of America (USA). The highest bibliometric component was science mapping, which was the theme in 30 (58%) articles. The majority of the bibliometric focus was clinical topics/fields (22 (42%) articles) and neurosurgeons/departments (21 (40%) articles). The most popular bibliometric metric was the h-index (±variants), which was employed in 22 (42%) articles. The median size of analyzed data was 188, and the most frequently utilized databases were Scopus (22 (42%) articles) and Web of Science (21 (40%) articles). The median (range) citation numbers were 52 (29-238). The citation analysis showed significantly higher citation numbers for older articles (aged ≥ 8 years) and studies published in the Journal of Neurosurgery. The citation rates were not influenced by the size of the data, the searched databases, or the bibliometric features. In conclusion, the most cited bibliometric research publications in the neurosurgical literature were predominantly descriptive analyses of clinical topics/fields and performance analyses of neurosurgeons/departments. Their citation numbers were relatively modest and were positively influenced by the publication's age and by a specific publishing journal but not by the bibliometric features of the study. Bibliometric research provides useful analytic tools that can be utilized in review studies and other practical purposes such as scholarly practices and policy decision-making.

[PMID: 38435088 PMCID: PMC10905953 DOI: 10.1016/j.reth.2024.02.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 02/15/2024] [Accepted: 02/16/2024] [Indexed: 03/05/2024] Open
Abstract
Over the past decades, there has been ongoing effort to develop complex biomimetic tissue engineering strategies for in vitro cultivation and maintenance of organoids. The defined hydrogels can create organoid models for various organs by changing their properties and various active molecules. An increasing number of researches has been done on the application of hydrogels in organoids, and a large number of articles have been published on the topic. Although there have been existing reviews describing the application of hydrogels in the field of organoids, there is still a lack of comprehensive studies summarizing and analyzing the overall research trends in this field. The citation can be used as an indicator of the scientific influence of an article in its field. This study aims to evaluate the application of hydrogels in organoids through bibliometric analysis, and to predict the hotspots and developing trends in this field.

World Neurosurg 2023; 173:115-121. [PMID: 36754352 DOI: 10.1016/j.wneu.2023.01.119] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 01/30/2023] [Accepted: 01/31/2023] [Indexed: 02/08/2023]
Abstract
BACKGROUND Cauda Equina Syndrome (CES) is a relatively uncommon and complex disorder. Recently, there has been a surge in research on CES. Although the research directions are multifarious, the overall research trends are unclear at present. We aimed to identify the 100 most cited articles on CES and analyze the hot spots trends regarding CES related research by bibliometric analysis. METHODS Articles were obtained by conducting an English language search of the Web of Science Core Collection Databases with the keywords "cauda equina syndrome." The initial 390 articles returned from the search were analyzed by VOSviewer. Next, the top 100 most cited articles were further analyzed by title, authors, journal, year of publication, total citations, country of origin, institution, and keywords. RESULTS A total of 390 publications were identified. The top 100 most cited articles were listed in descending order of total citations (range: 196-11). These articles originated from 24 countries; among these countries, the United Kingdom contributed the most publications (n = 29). The most prolific journal was Spine (n = 27), and the University of Edinburgh was the most productive institution (n = 9). CONCLUSIONS The number of publications on CES increased steadily, with a stable rise in recent years. Some publications have been cited more than 100 times, indicating that these findings are widely accepted by relevant clinicians and contribute significantly to the knowledge of CES. This study represents the first bibliometric analysis and visualization of hot spots analysis and research trends on CES. We believe that this will aid clinical researchers in targeting future areas of research.

Abstract
Coronavirus disease 2019 (COVID-19), beginning in December 2019, has spread worldwide, leading to the death of millions. Owing to the absence of definitive treatment, vaccination against COVID-19 emerged as an effective strategy against the spread of the pandemic. Acceptance of the COVID-19 vaccine has advanced considerably, and vaccine-related research has significantly increased over the past three years. This study aimed to evaluate the content and external characteristics of COVID-19 vaccine-related literature for tracking research trends related to the global COVID-19 vaccine with the means of bibliometrics and visualization maps. A total of 18,285 records in 3499 journals were retrieved in the Web of Science Core Collection database and included in the final analysis. China was the first to focus on COVID-19 vaccine research, while European and American countries started late but developed rapidly. The USA and the UK are the top contributors to COVID-19 vaccine development, with the largest number of publications. The University of Washington and Harvard Medical School were the leading institutions, while Krammer, F. from Icahn School of Medicine at Mount Sinai was the author most active and influential to the topic. The New England Journal of Medicine had the highest number of citations and the highest TLS, and was the most cited and influential journal in the field of COVID-19 vaccine research. COVID-19 vaccine research topics and hotspots focused on populations' attitudes towards vaccination, immunity-related information analysis of spike proteins, the effectiveness and side effects of the COVID-19 vaccine, and the public management of epidemic transmission. The findings of this study provide the global status, research hotspots and potential trends in the field of COVID-19 vaccine research, which will assist researchers in mastering the knowledge structure, and evaluating and guiding future developmental directions of COVID-19 vaccine.

Abstract
Objectives Drug-induced gingival overgrowth (DIGO) is a frequent adverse medication reaction that is generally caused by cyclosporine, phenytoin, and nifedipine, which belong to the category of immunosuppressants, anticonvulsants, and calcium channel blockers, respectively. This bibliometric analysis aims to depict the main citation characteristics and analyze the research trends in DIGO investigations. Methods An exhaustive search was performed in the Scopus database to create the bibliometric list of DIGO in the syntax. Furthermore, the information related to the number of citations, drugs related to DIGO, study topic and design, authorship, publication year, journal, contributing institution, country of origin, and the department was extracted. Results In total, 399 papers on DIGO were retrieved in this study. The total number of citations and that after the removal of self-citations were 7,814 and 7,314, respectively. The mean number of citations was 19.6 in a range of 0-608. The main paper types were articles (76.94%) and reviews (19.55%). A remarkable increasing trend in the number of citations has been observed since 1994. Cyclosporine (44.89%) is the most commonly used drug that shares a close relationship with DIGO, followed by phenytoin (18.22%), nifedipine (17.93%), and amlodipine (6.81%). The review (27.82%) type constituted the most widely used design in the DIGO studies. According to the top 20 keywords, the risk factors and pathogenesis of DIGO have been prominent topics of research works for several years. Conclusions This bibliometric analysis will facilitate the understanding of researchers and clinicians, especially those at the beginning of their careers in periodontology on DIGO, by identifying landmark research and providing an overview of this field.

Abstract
OBJECTIVE Clinical trials are essential for assessing advancements in spine tumor therapeutics. The purpose of this study is to characterize trends in clinical trials for primary and metastatic tumor treatments over the past two decades. METHODS ClinicalTrials.gov was queried using the search term "spine" for all interventional studies spanning 1999 to 2020 with categories of "Cancer", "Neoplasm", "Tumor", or "Metastasis". Tumor type, phase data, enrollment numbers and home institution country were recorded. The sponsor was categorized as academic institution, industry, government or other and intervention type as procedure, drug, device, radiation or other. Frequency of each category and cumulative frequency over twenty years were calculated. RESULTS 106 registered trials for spine tumors were listed. All except two that began before 2008 have been completed, enrollment of 51-100 subjects (29.8%) was the most common, and the majority were phase II (54.4%). Most examined metastatic tumors (58.5%) and new trials per year increased 3.4-fold between 2009 and 2020. The majority were conducted in the United States (56.4%). The most common intervention strategy was radiation (32.1%), although between 2010-2020 procedural studies became the most frequent (2.4 per year). The majority were sponsored by academic institutions (63.2%), and over twenty years have sponsored 3.2-fold more studies than industry partners. CONCLUSIONS The number of clinical trials for spine tumor therapies has rapidly increased over the past 15 years, driven by studies at United States academic medical institutions investigating radiosurgery for treatment of metastases. Targeted therapies for tumor subtypes and sequelae have updated international best practices.

Abstract
The history of academic research on ependymoma is expansive. This review summarizes its history with a bibliometric analysis of the 100 most cited articles on ependymoma. In March 2020, we queried the Web of Science database to identify the most cited articles on ependymoma using the terms “ependymoma” or “ependymal tumors,” yielding 3145 publications. Results were arranged by the number of times each article was cited in descending order. The top 100 articles spanned across nearly a century; the oldest article was published in 1924, while the most recent was in 2017. These articles were published in 35 unique journals, including a mix of basic science and clinical journals. The three institutions with the most papers in the top 100 were St. Jude Children’s Research Hospital (16%), the University of Texas MD Anderson Cancer Center (6%), and the German Cancer Research Center (5%). We analyzed the publications that may be considered the most influential in the understanding and treatment management of ependymoma. Studies focused on the molecular classification of ependymomas were well-represented among the most cited articles, reflecting the field’s current area of focus and its future directions. Additionally, this article also offers a reference for further studies in the ependymoma field.

Abstract
STUDY DESIGN Bibliometric literature review. OBJECTIVE The aim of this study was to recognize and analyze the most frequently cited manuscripts published in the journal Spine. SUMMARY OF BACKGROUND DATA Although the journal Spine is considered a premiere location for distributing influential spine research, no previous study has evaluated which of their publications have had the most impact. Knowledge and appreciation of the most influential Spine publications can guide and inspire future research endeavors. METHODS Using the Scopus database, the 100 most cited articles published in Spine were accessed. The frequency of citations, year of publication, country of origin, level-of-evidence (LOE), article type, and contributing authors/institutions were recorded. The 10 most cited articles (per year) from the past decade were also determined. RESULTS "Guidelines For The Process Of Cross-Cultural Adaptation Of Self-Report Measures" by Beaton DE was the most cited article with 2960 citations. 2000 to 2009 (n = 46) was the most productive period. A LOE of III (n = 35) followed by II (n = 34) were the most common. Deyo RA (n = 8), Bombardier C (n = 6), and Waddell G (n = 6) produced the most articles. University of Washington (n = 8) and University of Toronto (n = 8) ranked first for institutional output. Clinical Outcome (n = 28) was the most recurring article topic. The United States (n = 51) ranked first for country of origin. CONCLUSION Using citation analysis as an objective proxy for influence, certain publications can be distinguished from others due to their lasting impact and recognition from peers. Of the top cited Spine publications, many pertained to clinical outcomes (28%) and had a LOE of I, II, or III (60%). Although older publications have had longer time to accrue citations, those in the most recent decade comprise this list almost 2:1. Knowledge of these "classic" publications allows for a better overall understanding of the diagnosis, management, and future direction of spine health care.Level of Evidence: 3.

Orthop J Sports Med 2020; 8:2325967120967082. [PMID: 33816639 PMCID: PMC8008137 DOI: 10.1177/2325967120967082] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2020] [Accepted: 06/15/2020] [Indexed: 02/05/2023] Open
Abstract
Background: Citation counts have often been used as a surrogate for the scholarly impact of a particular study, but they do not necessarily correlate with higher-quality investigations. In recent decades, much of the literature regarding shoulder instability is focused on surgical techniques to correct bone loss and prevent recurrence. Purpose: To determine (1) the top 50 most cited articles in shoulder instability and (2) if there is a correlation between the number of citations and level of evidence or methodological quality. Study Design: Cross-sectional study. Methods: A literature search was performed on both the Scopus and the Web of Science databases to determine the top 50 most cited articles in shoulder instability between 1985 and 2019. The search terms used included “shoulder instability,” “humeral defect,” and “glenoid bone loss.” Methodological scores were calculated using the Modified Coleman Methodology Score (MCMS), Jadad scale, and Methodological Index for Non-Randomized Studies (MINORS) score. Results: The mean number of citations and mean citation density were 222.7 ± 123.5 (range, 124-881.5) and 16.0 ± 7.9 (range, 6.9-49.0), respectively. The most common type of study represented was the retrospective case series (evidence level, 4; n = 16; 32%) The overall mean MCMS, Jadad score, and MINORS score were 61.1 ± 10.1, 1.4 ± 0.9, and 16.0 ± 3.0, respectively. There were also no correlations found between mean citations or citation density versus each of the methodological quality scores. Conclusion: The list of top 50 most cited articles in shoulder instability comprised studies with low-level evidence and low methodological quality. Higher-quality study methodology does not appear to be a significant factor in whether studies are frequently cited in the literature.

Brown NJ, Wilson B, Shahrestani S, Choi EH, Lien BV, Paladugu A, Tran K, Ransom SC, Tafreshi AR, Ransom RC, Sahyouni R, Chan AY, Yang I. The 100 Most Influential Publications on Medulloblastoma: Areas of Past, Current, and Future Focus. World Neurosurg 2020; 146:119-139. [PMID: 33212273 DOI: 10.1016/j.wneu.2020.11.038] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Revised: 11/07/2020] [Accepted: 11/07/2020] [Indexed: 11/17/2022]
Abstract
BACKGROUND This article is the first to identify the most influential articles on medulloblastoma using the citation analysis methodology. OBJECTIVE To perform a bibliometric analysis of the 100 most-cited articles on medulloblastoma. METHODS Using the Web of Science database, search criteria included the title-specific keyword "medulloblastoma" OR "cerebellar primitive neuroectodermal tumor (PNET)" OR "cerebellar PNET." Publications from 1900 to 2020 labeled "article," "review," "data set," or "clinical trial" were chosen and ranked based on total number of citations in descending order. Each article was evaluated based on the following variables: total citations, average citations per year, first author, institution of first author, title, publication year, country of origin, SCImago Journal Rank, and Scopus SNIP (Source Normalized Impact per Paper). RESULTS Our search yielded 4928 articles on medulloblastoma. The 100 most-cited articles ranged from 192 to 2017 across 42 unique journals; Journal of Clinical Oncology accounted for the most publications (16%). Paul A. Northcott was first author of the most articles on the list (n = 7.7%), and the most widely cited article was "Altered neural cell fates and medulloblastoma in mouse patched mutants" by Goodrich et al., published in Science (1997). CONCLUSIONS Because medulloblastoma represents the most common form of pediatric cancerous brain tumor, it is important to identify works that have significantly contributed to the body of knowledge regarding this disease. The 100 most-cited medulloblastoma articles comprise a significant collection of data regarding the histopathologic and molecular classification of medulloblastoma as well as clinical outcomes of therapeutics used to treat this disease.

Abstract
OBJECTIVE The objective of this study was to determine the publication rate of abstracts presented at the annual meetings of the AANS/CNS Section on Disorders of the Spine and Peripheral Nerves (Spine Summit). METHODS The authors used a search algorithm in PubMed to determine the publication rate of abstracts presented at the Spine Summit from 2007 to 2012. The variables assessed were presentation modality, topic, meeting year, publication year, destiny journal and its 5-year impact factor (IF), country, and citation count (retrieved from the Scopus database). RESULTS One thousand four hundred thirty-six abstracts were analyzed; 502 were oral presentations and 934 were digital poster presentations. The publication rate was 53.97% (775/1436). The mean time from presentation to publication was 1.35 ± 1.97 years (95% CI 1.21-1.49 years). The mean citation count of published articles was 40.55 ± 55.21 (95% CI 36.66-44.44). Oral presentations had a higher publication rate (71.51%, 359/502) than digital posters (44.54%, 416/934; OR 3.13, 95% CI 2.48-3.95, p < 0.001). Oral presentations had a higher number of citations (55.51 ± 69.00, 95% CI 48.35-62.67) than digital posters (27.64 ± 34.88, 95% CI 24.28-31.00, p < 0.001). The mean IF of published articles was 3.48 ± 2.91 (95% CI 3.27-3.70). JNS: Spine (191/775, 24.64%), Spine (103/775, 13.29%), and Neurosurgery (56/775, 7.23%) had the greatest number of published articles. The US represented the highest number of published articles (616/775, 79.48%). CONCLUSIONS The publication rate of the Spine Summit is among the highest compared to other spine meetings. Many of the abstracts initially presented at the meeting are further published in high-IF journals and had a high citation count. Therefore, the Spine Summit maintains its high standards of scientific papers, which reflects the high quality of the research performed in the spine surgery field in North America.

Abstract
Purpose The aim of this study was to identify the 100 most cited research articles in prostate cancer brachytherapy (PCB) and to review the characteristics of these citation. Material and methods The Web of Science Core Collection was used to identify the 100 most cited articles in PCB as of December 31st, 2019. The following important information was extracted: year and month of publication, title, journal, country of origin, authors, type of article, treatment modality, and topics. Results The 100 most cited articles in PCB were published between 1999 and 2018, and the number of citations ranged from 455 to 54; these articles had collectively been cited 10,331 times at the time of search. These articles were from 11 countries, with most publications being from the United States (n = 61), followed by Canada (n = 10), the United Kingdom (n = 8), and Germany (n = 5). The “International Journal of Radiation Oncology, Biology, Physics” published the most articles (n = 47), followed by the “Journal of Urology” (n = 11), “Radiotherapy and Oncology” (n = 10), “Cancer” (n = 7), and “Urology” (n = 6). Permanent interstitial brachytherapy (n = 52) was the most widely used treatment modality, followed by temporary brachytherapy (n = 45). Disease control (n = 51) was the most common topic, followed by side effects (n = 44) and quality of life (n = 27). Conclusions The bibliometric analysis presents a detailed list of the 100 most cited articles in prostate cancer brachytherapy. There are clear recommendations for treatment with prostate cancer brachytherapy. The goal of prostate cancer brachytherapy is to improve long-term outcomes and quality of life.

Abstract
BACKGROUND A vast amount of articles centered on brain metastases have been published. OBJECTIVE To present the 100 most-cited articles dedicated to brain metastasis and to accomplish a broad literature review. METHODS In December 2019, we performed a title-focused search using the Thomson Reuters Web of Science database to identify the most cited articles centered on brain metastatic disease. Our search query term was based on using the following algorithm: "brain metastases" OR "brain metastasis" OR "brain metastatic disease" OR "cerebral metastases" OR "cerebral metastasis" OR "cerebral metastatic disease." Afterward, we reviewed the results to certify that they were relevant to the purposes of our research protocol. The 100 most cited papers were chosen and further analyzed. RESULTS Our search resulted in 11,579 articles, published from 1975 until the completion of our survey. The most cited article, by Patchell et al., was published in 1990, with 1862 citations, and an average of 62.07 citations per year, whereas the last in our list, by Gaspar et al., was published in 2010, with 195 total citations, and an average of 19.50 citations per year. Countries with the highest-cited articles included the United States (75 records), followed by Canada (16 records). CONCLUSIONS We discovered the top 100 most-cited articles centered on brain metastasis, all of which show a potentially increased level of interest, because they are meaningful scientific reports. In addition, we reviewed the historical development and advances in brain metastasis research and relevant points of interest, alongside the relevant contributions of different authors, fields of special interest, and countries. Many of the most cited articles were written by authors whose specialty was not neurosurgery or by neurosurgeons who were supported by colleagues from other medical fields. As a consequence, many of these articles were not published in neurosurgery-dedicated journals.

Abstract
BACKGROUND Contributions from Latin America to the global literature are scarce; until 2011, spine surgeons had published 320 articles in indexed journals. METHODS This systematic review evaluates the scientific production of the Mexican Association of Spine Surgeons (Asociación Mexicana de Cirujanos de Columna-AMCICO) from its inception in 1998 to 2018 with the PRISMA statement using PubMed and Google Scholar search engines. The inclusion criteria were spine-related articles in indexed journals providing any (or no) level of evidence with ≥1 AMCICO member as an author. Journal metrics, article metrics, and author variables were analyzed using SPSS version 25. RESULTS Of the 444 surgeons historically belonging to AMCICO, only 126 members contributed a total of 441 articles between 1998 and 2018. An average of 21.00 annual publications with an annual scientific output per capita of 0.05 was found. The most frequent evidence level was III (211 articles, 48%), the highest level was I (12 articles, 3%). The main study objective was clinical research, with 308 articles (70%), and the main study foci was trauma, with 103 articles (23%). An average impact factor of 0.16 and 0.92 was obtained for publications in Spanish and English, respectively. CONCLUSIONS Scientific publications by AMCICO members are scarce, with a per capita annual index of 0.05 from a total of 441 articles in indexed journals. Second, the impact factor of these journals is low, with a mean value of 0.53. Further strategies should be implemented to increase the number and track the record of Mexican contributions to the scientific literature.

Abstract
BACKGROUND Atlantoaxial spine surgery is a challenge to spinal surgeons because of its proximity to neurovascular structures. This study aimed to identify and analyze the scientific publications in atlantoaxial spine surgery from different countries and institutions. METHODS Clarivate Analytics Web of Science was used to search all articles for information on atlantoaxial spine surgery. The annual research, countries, journals, authors, institutions, citation frequency, and journal metrics were extracted. These results from countries and hotspots (keywords in publications) were subjected to co-occurrence analysis using VOSviewer, after which the top 100 most-cited articles were analyzed further. RESULTS A total of 3161 articles were included. A trend toward an increasing number of publications on atlantoaxial spine surgery in recent years was evident. Among all countries, the United States contributed the most publications. Seth Gordhandas Sundarda Medical College had the highest number of publications among institutions. Among all research categories, fixation and fusion were the most common areas discussed. The screw-rod system described in the most-cited article (cited 823 times) appeared to be the most popular fixation method. With the development of C1 and C2 screw technology, the screw-rod system is becoming increasingly popular. CONCLUSIONS The atlantoaxial spine surgery literature has grown continuously in recent years. The United States is the largest contributor in this field. Fixation and fusion are the most common areas, and fixation-related studies should be closely followed. The screw-rod fixation system is becoming increasingly popular.

Abstract
STUDY DESIGN Bibliometric analysis. OBJECTIVES To identify the 100 most cited orthopedic papers in adolescent idiopathic scoliosis (AIS) over the past 25 years and characterize them by study type, topic, and country and assess study quality (design, level of evidence, and impact factor) to provide an updated account of the most impactful AIS evidence. AIS represents a three-dimensional deformity that drives a significant number of investigations. Although available evidence continues to grow, recent impactful studies pertaining to AIS have not been identified; their quality has not been thoroughly assessed. METHODS Web of Science was reviewed to identify the top 1000 cited AIS studies published from 1992 to 2017. Articles were organized by number of citations. Titles and abstracts were screened for inclusion/relevance, and the top 100 articles by citation count were identified, and study and publication characteristics were extracted. RESULTS Among the top 100 articles, 42 were cited ≥ 100 times. Mean number of authors and citations of these studies was 5.6 and 118.3, respectively. Study types were predominantly retrospective (n = 53), followed by prospective (n = 18), cross-sectional (n = 13), and systematic review/meta-analysis (n = 7). Topics covered in these studies included clinical/patient outcomes (n = 47), methodology/validation (n = 22), basic science (n = 15), radiographic analyses (n = 12), and gait/biomechanics (n = 4). Most studies originated in the United States of America (n = 65) and were published in Spine (n = 76), with 8266 total citations. Most studies were of Level III (n = 55) or Level II (n = 23) evidence. Mean impact factor was 3.47. CONCLUSIONS Despite recent studies' shorter time frames for impact, citations of AIS research have progressively increased during the past 25 years. The top 100 cited orthopedic studies were predominantly Level III, retrospective, nonrandomized studies, and therefore, were subject to biases. The low proportion of prospective studies (18%) reflects an area of future improvement, underscoring the need for higher-quality studies to support our practice. LEVEL OF EVIDENCE N/A.

Abstract
INTRODUCTION Citation analysis has been used to evaluate the impact of papers in medicine. There has been multitude of orthopaedic oncology-related papers in literature, to our knowledge no citation analysis of orthopaedic oncology papers has been performed. We identified the 50 most-cited orthopaedic oncology papers and evaluated these papers in terms of their time of publication, source journals, countries, institutions, authors, and main topics. MATERIALS AND METHODS Science citation index expanded was searched in April 2018 for citations of papers published in 77 selected journals since the beginning of the database. The 50 most-cited orthopaedic oncology papers were identified and evaluated. RESULTS The number of citations for the top 50 papers ranged from 168 to 1162 (mean 308). These papers were published between 1957 and 2010. 1990s was the most productive decade, with 19 papers of the list. All papers were written in English and they were published in a total of 6 journals. The Journal of Bone and Joint Surgery-Am published the largest number of papers with 31, followed by Clinical Orthopaedics and Related Research with 8. The top 50 papers were created mainly from US and Japan, respectively, with 33 and 5. CONCLUSIONS It is difficult to define the exact impact of a single paper in the literature. In doing citation analysis, it provides us perspective in the history and progress of orthopaedic oncology.

Abstract
INTRODUCTION Publication rate can indirectly assess the quality of research presented in scientific meetings. Considering presentations at orthopedic surgery and neurosurgery meetings, 10.5-66% of abstracts are published in scientific journals. Publication rate of abstracts presented at CSS Meetings is unknown. The objective of this study was to evaluate the publication rate of abstracts presented at the Canadian Spine Society(CSS) Annual Meetings from 2005to2014. METHODS In October2018, a systematic PubMed search was performed using title and authors of all abstracts presented at CSS Meetings from 2005 to 2014. The following information was retrieved from the articles and abstracts: year, type of presentation, publication in PubMed, time from presentation to final publication, journal and its impact factor(IF). RESULTS A total of 621 abstracts were presented at CSS meetings from 2005 to 2014. Publication rate in PubMed was 54.8%(N=340/621). Oral presentations were more likely to be published than poster presentations(63.8%vs44.0%; OR=1.45; CI95%=1.20-1.75; P<0.0001). The mean time from presentation to publication was 1.76 years(±1.93). The 340 identified articles were published in 87 different journals. Most common journals were Spine(N=75; 22.1%), The Spine Journal(N=40;11.8%), and Journal of Neurosurgery:Spine(N=28;8.2%). IF ranged from 0.18 to 47.66(mean=3.73±4.68). IF of articles presented orally were higher than those presented as poster(P=0.038). CONCLUSIONS The CSS scientific meeting maintain along the years a steady high quality research presentations as manifested by its significant publication rate(54.8%) in medical journals with mean IF of 3.73. In comparison with other spine scientific meetings, publication rates of abstracts presented at CSS meeting is amongst the highest.

Abstract
Intra-abdominal pressure (IAP) is a physiological parameter that has gained considerable attention during the last few decades. The incidence of complications arising from increased IAP, known as intra-abdominal hypertension (IAH) or abdominal compartment syndrome in critically ill patients, is high and its impact is significant. The effects of IAP in neurological conditions and during surgical procedures are largely unexplored. IAP also appears to be relevant during neurosurgical procedures (spine and brain) in the prone position, and in selected cases, IAH may affect cerebrospinal fluid drainage after a ventriculoperitoneal shunt operation. Furthermore, raised IAP is one of the contributors to intracranial hypertension in patients with morbid obesity. In traumatic brain injury, case reports described how abdominal decompression lowers intracerebral pressure. The anatomical substrate for transmission of the IAP to the brain and venous system of the spine is the extradural neural axis compartment; the first reports of this phenomenon can be found in anatomical studies of the sixteenth century. In this review, we summarize the available knowledge on how IAP impacts the cerebrospinal venous system and the jugular venous system via two pathways, and we discuss the implications for neurosurgical procedures as well as the relevance of IAH in neurological disorders.

Abstract
Clubfoot is an important aspect of pediatric orthopedics and is a readily prevalent condition presenting to orthopedic clinics worldwide. To identify landmark articles and important contributions to this field, we sought to do a citation analysis of the top 100 most-cited articles on clubfoot. Using the Scopus database and the search strategy 'Clubfoot', 'Clubfeet' OR 'Talipes Equinovarus', we identified 5753 articles. After filtering for relevant articles, the top 100 cited articles on clubfoot were retrieved for descriptive and statistical analysis. The most cited paper was 'Long-term results of treatment of congenital clubfoot' by S.J. Laaveg and I.V. Ponseti with 358 citations. The publication years ranged from 1969 to 2011. The USA was the most productive country in terms of research output, followed by the UK. Institution-wise, the University of Iowa contributed the most in terms of number of publications. The Journal of Pediatric Orthopaedics held the most number of articles. Most publications were level IV and level V studies. Although citation analysis has it flaws, this is a comprehensive list of the top 100 articles significantly affecting literature on clubfoot. On the basis our study, we conclude that there is marked deficiency of high-level articles with respect to the number of citations, and future researches need to cater to this question to produce high-quality studies.

Abstract
Total number of citations has been considered a proxy for a published study's importance within a given field. However, there are multiple pitfalls to correlating the total number of citations alone with the quality of a study. In this review, the authors aimed to identify the top 100 most-cited studies of hip and knee arthroplasty and then assess study design and quality of reporting. More than half of these studies were level IV evidence, unblinded, not randomized, and not controlled. This underscores the need for higher-quality study design to support practice.

Abstract
Background Management of spine fractures has advanced considerably even over the past decade. A review of the current and historical literature can lead to a better appreciation of current management protocols. This is the first comprehensive review of the most influential articles related to spine fracture management. The purpose of this study is to identify and analyze the 100 most cited publications in spine fracture management. Methods Using the Clarivate Analytics Web of Science, search phrases were used to identify publications pertaining to spine fractures (110,809 publications). The 100 most cited articles were isolated. The frequency of citations, year of publication, country of origin, journal of publication, level-of-evidence (LOE), article type, and contributing authors/institutions were recorded. We also highlighted the ten most cited articles (per year) from the past decade. Results The publications included ranged from 1953-2010, with the majority published between 2000-2009 (n=41). Total citations ranged from 154 to 1,076. A LOE of IV had the plurality at 36%. The most cited article was "The 3 Column Spine and Its Significance in The Classification of Acute Thoracolumbar Spinal-Injuries" (Spine 1983) by F Denis. The majority of papers originated in the United States (n=65), and the highest number were published in Spine (n=27). Osteoporotic fractures were the specific topic in 34 publications. In the past decade, the article with the most citations/year was "A Randomized Trial of Vertebroplasty for Osteoporotic Spinal Fractures" by DF Kalmes in 2009. Conclusions Despite less time for citation than other decades, the 2000s contain the plurality of the influential publications. This may indicate that some of the most important changes to spine fracture management pertain to improved imaging modalities and surgical technologies. This review provides a guide for a comprehensive understanding of the historical and current literature pertaining to spine fracture management.

Abstract
PURPOSE The infection is an essential problem in the clinical practice in orthopedics. The bibliometric analysis was conducted to evaluate the top 100 cited articles on infection in orthopaedics. METHODS The Web of Science (WoS) Core Database was comprehensively searched from 1975 to 2017, and the literature search was limited in Science Citation Index Expanded (SCI-E). The subject terms included "infection", "infectious", and "infect*". All retrieved articles were filtrated by selecting the subspecialty of "Orthopedics". The searching results were listed by citation times to identify the top 100 cited articles. Significant information was elicited, including the authors, journals, countries, institutions, published year, and types of publication. RESULTS A significant increase was observed in the number of annual publications focusing on infection in orthopedics worldwide. Each of the top 100 cited articles was cited more than 150 times. Total citation times was positively associated with citation times in 2016 (P <.01) and mean citation times per year (P <.01). Conversely, age of the article was negatively associated with citation times in 2016 (P <.01) and mean citation times per year (P <.01). Besides, citation times in 2016 was positively related to mean citation times per year (P <.01). The United States was the most productive country, surgery was the most popular subspecialty and Journal of Bone and Joint Surgery American Volume was the most popular journal. CONCLUSION Infection in orthopaedics has attracted more and more researchers' concern. As for the top 100 cited articles, there were significant relationships among total citation times, citation times in 2016 and mean citation times per year as well as age of the article. The United States was the most productive country, surgery was the most popular subspecialty and Journal of Bone and Joint Surgery American Volume was the most popular journal.

Abstract
Management of cervical myelopathy (CM) has continued to evolve through a better understanding of the long-term outcomes of this diagnosis as well as improved diagnostic guidelines. More recent literature continues to expand the field, but certain publications can be distinguished from others due to their lasting impact. Using the Clarivate Analytics Web of Science, search phrases were used to identify publications pertaining to CM. The fifty most cited articles were isolated. The frequency of citations, year of publication, country of origin, journal of publication, level of evidence (LOE), article type, as well as contributing authors and institutions were recorded. We also highlighted the five most cited articles (per year) from the past 10 years. Publications included ranged from 1952-2011, with the plurality of articles published during 2000-2009 (n=21; 42%). The most cited paper was Hillibrand's 1999 reporting of adjacent segment disease rates following cervical fusions, followed by Hirabayashi's 1983 review of his cervical laminoplasty outcomes. The third most cited was Brain's 1952 review of the manifestations of cervical spondylosis. Spine contributed the most publications (n=26; 52%). A LOE of III was the most common (n=30; 60%). Clinical outcome articles were the most frequent type (n=28; 56%). Osaka University (Japan) and Kazou Yonenobu had the most contributions. Ames or Fehlings were the first or last author in each of the five most influential articles from the past 10 years. This bibliometric citation analysis identifies the most influential articles regarding CM. There are few publications with a high LOE, and more high powered studies are needed. Knowledge of these "classic" publications allows for a better overall understanding of the diagnosis, treatment, and future direction of research of CM.

Malik AT, Jain N, Yu E, Khan SN. The Top 50 Most-Cited Articles on Cervical Spondylotic Myelopathy. World Neurosurg 2018; 116:e1168-e1180. [PMID: 29870842 DOI: 10.1016/j.wneu.2018.05.191] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2018] [Revised: 05/25/2018] [Accepted: 05/26/2018] [Indexed: 11/29/2022]
Abstract
BACKGROUND Cervical spondylotic myelopathy (CSM) occurs due to chronic degenerative changes in the cervical spine causing compression of the spinal cord. CSM has been studied for decades, and numerous articles have been published on the topic. We sought to identify the top 50 most-cited articles on CSM. METHODS The top 50 most-cited articles were retrieved from the Scopus database using the search criteria "cervical spondylosis with myelopathy" OR "cervical spondylotic myelopathy." Levels of evidence were also calculated and descriptive and statistical analyses were carried out. RESULTS The total number of citations of the top 50 most-cited papers was 7072. The paper with the highest number of citations had 287. All articles were published between 1966 and 2010, with most published between 1990 and 1999 (n = 22). The most prolific country in terms of the total number of publications was United States, with 25 publications, followed by Japan. The majority of the articles were level IV. CONCLUSIONS There is a deficiency of high-level articles in the top 50 most-cited list. This study provides an important overview of historical development of treatment methods, as well as publication trends related to this pathology. Regardless, this comprehensive list of the top 50 most-cited articles can serve as a resource for future trainees and surgeons to draw on to build their knowledge base.

Almutairi O, Albakr A, Al-Habib A, Ajlan A. The Top-100 Most-Cited Articles on Meningioma. World Neurosurg 2017; 107:1025-1032.e5. [PMID: 28804043 DOI: 10.1016/j.wneu.2017.08.021] [Citation(s) in RCA: 36] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2017] [Revised: 07/31/2017] [Accepted: 08/01/2017] [Indexed: 12/16/2022]
Abstract
BACKGROUND There is an abundance of articles published on meningioma. OBJECTIVE To identify the 100 most-cited articles on meningioma and to perform a bibliometric analysis. METHODS In November 2016, we performed a title-specific search of the Scopus database using "meningioma" as our search query term without publication date restrictions. The top 100 most cited articles were obtained and reviewed. RESULTS The top 100 most cited articles received a mean 198 citations per paper. Publication dates ranged from 1953 to 2013; most articles were published between 1994 and 2003, with 50 articles published during that period. NEUROSURGERY published the greatest number of top cited articles (22 of 100). The most frequent study categories were laboratorial studies (31 of 100) and natural history studies (28 of 100). Nonoperative management studies were twice as common as operative management studies in the top-cited articles. Neurosurgery as a specialty contributed to 50% of the top 100 list. The most contributing institute was the Mayo Clinic (11%); the majority of the top cited articles originated in the United States (53%). CONCLUSIONS We identified the top 100 most-cited articles on meningioma that may be considered significant and impactful works, as well as the most noteworthy. In addition, we recognized the historical development and advances in meningioma research and the important contributions of various authors, specialty fields, and countries. A large proportion of the most cited articles were written by authors other than neurosurgeons, and many of these articles were published in non-neurosurgery journals.
