How changed publication of hip and knee arthroplasty between 2005-2014 years. What we missed?
Abstract: The PubMed, EBSCO Health MedLine and ScienceDirect database was utilized with the similar advanced search to retrieve the corresponding result. Numbers of publication of hip and knee arthroplasty were searched separately on each database with advanced search using the following search terms: (Knee arthroplasty) or (Knee replacement) and (Hip arthroplasty) or (Hip replacement) included publication dates for 10 year from 2005.01.01 to 2014.12.31. Within a formula for the arithmetic mean definition we determined the average measurement of publication of hip and knee arthroplasty. All obtained data were analyzed and formed on the tables and graphs figures using Microsoft Excel for Windows 2013. The cases with hip arthroplasty or hip replacement in PubMed over the 10 years period were 17.939, which increased from 1354 to 2772 between 2005-2014 years. EBSCO Health Medline publications were 17,783, which similarly increased from 1342 to 2235 between 2005-2014 years. And ScienceDirect publications were 29,970 and grew from 1857 to 3600 in period 2005-2014. The hip arthroplasty publication arithmetic mean was increased from 1518 to 2702 between the 2005-2014 years, when the knee arthroplasty publication arithmetic mean was growing from 1136 to 2771. Percent ratio shows that the growth rate of publications knee arthroplasty 10% was faster than hip arthroplasty 7% during the 10 years. Publication of materials knee arthroplasty have been sharply increased during the last years, it shows that the interest in study about problems knee arthroplasty have been increased in conjunction.
Keywords: Hip arthroplasty; knee arthroplasty; language of publication.
Introduction of publication trends hip and knee arthroplasty in last years [13;
In length of time the number of hip and knee arthroplasty sur- 25; 26; 31]. gery has been increased. [1; 2; 3; 4] in parallel the number of re- Most ofpublished studies show that many authors were pointed
search related to this issue has been enlarged [5; 6; 7; 8]. The study to studying various peculiar properties such as analysis publication and research of scientific publications in a specific sphere, in inter- trends in one field, different publication rates between countries national bibliographic databases, is one of the frequently used meth- and journals [14; 15]. Despite the importance publication trends of ods of evaluation the scrutiny of this topic [9; 10; 11; 12]. While the hip and knee arthroplasty were insufficiently studied and pub-reviewing published orthopedic researches and articles in scientific lished in scientific journals [16; 17]. We know that many research-journals, we convinced that only a few articles were published about ers and scholars even clinician doctors commonly use the PubMed
database which comprises over 24 million citations for biomedical literature contains a digital archive of4,800 biomedical and life sciences journals in 30 languages, which were selected by the National Library of Medicine's Literature Selection Technical Review Committee. These articles were selected on a worldwide basis for their scientific merit, validity, importance, originality, and contribution [14; 18] and ScienceDirect delivers over 13 million publications from nearly 2,500 journals and more than 33,000 books from Elsevier or EBSCOhost MedLine Complete that is the largest companion to the MedLine index and provides full text for over 2,500 medical journals [19; 20].
The purpose of this study was to more in-depth analysis of the dynamics ofpublication of the hip and knee arthroplasty for the last 10 years. Accordingly, we decided to study:
1. Searching the difference publications on topics ofhip and knee arthroplasty PubMed, EBSCO Health MedLine and ScienceDirect.
2. Analysis and study of the relationship between publications of hip and knee arthroplasty in PubMed, EBSCO Health MedLine and ScienceDirect.
3. Determination of the ability to reach and use of hip and knee arthroplasty scientific articles with analysis published cases on EBSCO Health MedLine and study the status of the language of publication the example of the Russian part of the publication.
Materials and Methods
The PubMed, EBSCO Health MedLine and ScienceDirect database was utilized with the similar advanced search to retrieve the corresponding result. Numbers of publication of hip and knee arthroplasty were searched separately on each database with advanced search using the following search terms: (Knee arthroplasty) or (Knee replacement) and (Hip arthroplasty) or (Hip replacement) included publication dates for 10 year from 2005.01.01 to 2014.12.31. Publication date results were further refined for years, by using the search option "Results by year". To determine the total number of citations were found all source types, journal, magazines, guidelines, books and reference work articles include online internet publications with the word (All) for each available text and article types.
The total number of citations (Hip arthroplasty) or (Hip replacement) available in PubMed searching with (("hip" [MeSH Terms] OR "hip" [All Fields]) AND ("arthroplasty" [MeSH Terms] OR "arthroplasty" [All Fields])) OR ("arthroplasty, replacement, hip" [MeSH Terms] OR ("arthroplasty" [All Fields] AND "replacement" [All Fields] AND "hip" [All Fields]) OR "hip replacement arthroplasty" [All Fields] OR ("hip" [All Fields] AND "replacement" [All Fields]) OR "hip replacement" [All Fields]) AND ("2005/01/01" [PDAT]: "2014/12/31" [PDAT]) and calculating by years results were 17.939. And citations (Knee arthroplasty) or (Knee replacement) with using ("arthroplasty, replacement, knee" [MeSH Terms] OR ("arthroplasty" [All Fields] AND "replacement" [All Fields] AND "knee" [All Fields]) OR "knee replacement arthroplasty" [All Fields] OR ("knee" [All Fields] AND "arthroplasty" [All Fields]) OR "knee arthroplasty" [All Fields]) OR ("arthroplasty, replacement, knee" [MeSH Terms] OR ("arthroplasty" [All Fields] AND
"replacement" [All Fields] AND "knee" [All Fields]) OR "knee replacement arthroplasty" [All Fields] OR ("knee" [All Fields] AND "replacement" [All Fields]) OR "knee replacement" [All Fields]) AND ("2005/01/01" [PDAT]: "2014/12/31" [PDAT]) and calculating by years results accounted 15.214.
EBSCO Medline Complete results the (Hip arthroplasty) or (Hip replacement) with select optional fields, search modes (Find all my search terms), (All) age related, sex, subject subset, clinical queries, journal and citation subset, publication type and other search options from 2005.01.01 to 2014.12.31 date publication period were 17,783 cases and the (Knee arthroplasty) or (Knee replacement) were indicate 15.103.
Amount of the total ScienceDirect (Hip arthroplasty) or (Hip replacement) search was provided with expert search all publication in all journals and books and reference work which showed search results: 29,970 results found for pub-date > 2004 and pub-date < 2015 and All (hip arthroplasty) or All (hip replacement) pdt AFT 20050101, whereas the data of the search results: 26,175 results found for pub-date > 2004 and pub-date < 2015 and All (knee arthroplasty) or All (knee replacement) pdt AFT 20050101 after re-counted by years result.
We used the formula for the arithmetic mean definition to determine the average measurement ofpublication ofhip and knee arthroplasty in PubMed, EBSCO Health MedLine and ScienceDirect.
AMP =1 a. =1 (al + a2 +... + an )
n '=i ' n
AMP—Arithmetic mean ofhip and knee arthroplasty in PubMed, EBSCO Health MedLine and ScienceDirect, n — amount of databases, a — the number ofpublications per year on a single database.
For retrospective analysis and estimate of ratio between the Russian languages publication of the Hip and Knee arthroplasty in the EBSCO Health MedLine and publication quantity in the journal Traumatology and orthopedics of Russia separately were searched from the database sites online.
Statistical analysis
All obtained data were analyzed separately, compared and formed on the tables and graphs figures using Microsoft Excel for Windows 2013. The publication rates were calculated as a relative percentage when compared to the total number of publications retrieved in the study. Statistical analysis was performed using SPSS software for Windows (version 20.0, SPSS Inc., Chicago, IL) for variables including the year of publication, number of authors, country of origin, and institution type. P-values < 0.05 were considered statistically significant.

Our results show that the number of publications hip and knee arthroplasty was increased during the period 2005-2014, only the number of publications in ScienceDirect was more than others. Ratio of publication hip and knee arthroplasty The hip arthroplasty publication arithmetic mean was increased from 1518 to 2702 between the 2005-2014 years, when the knee arthroplasty publication arithmetic mean was growing from 1136 to 2771. Percent ratio shows that the growth rate of publications knee
arthroplasty 10% was faster than hip arthroplasty 7% during the 10 years.
The graph shows us that the publication arithmetic mean hip and knee arthroplasty have a very big difference between each other at the beginning of last over the 10 years with the advantage hip arthroplasty. But the index of publications in recent years shows an equation the knee arthroplasty with the publication of the hip. (Figure 1).

Status of the language of publications
A large number of publications have been made over the 10 years by EBSCO Health Medline of more than 40 languages, but
the publications about the hip arthroplasty were 60 from 17,783 and the knee arthroplasty were 21 in Russian from 15,103 of all search results. However in the journal Traumatology and orthopedics of
Russia where published 118 hip arthroplasty and 39 knee arthroplasty articles, abstracts, thesis and other materials in Russian and English per the studying period (Figure 2).
This shows that the large number of journals and publication of articles in specific sources cannot display all the real number of publications in certain research scale without the extensive involvement of many of the major journal and references from all over the world.
Discussion
The present study aimed at exploring the level ofevidence of published articles in the field of hip and knee arthroplasty per years 20052014 and we have combined data from three different sources PubMed, EBSCO Health MEDLINE and the ScienceDirect to estimate the publication arithmetic mean hip and knee arthroplasty in this database.
Good clinical methods should be based on the existing evidence based on scientific publications and research (24). Many authors have investigated the level of hip and knee arthroplasty publications in some region, relative publication between countries, study clinical outcomes publication or rates ofpublication by years in only one database [7; 15; 16; 17; 27]. However, we decided to explore publication trends ofknee and hip arthroplasty within 10 years in three databases.
Despite some authors show a very high increase of the number ofpublication [15], and even some authors argue with decline percent of publication in some countries [17], In our findings the publication arithmetic mean hip arthroplasty in PubMed, EBSCO Health MedLine and the ScienceDirect datebases have been increased from 1518 to 2702 when the knee arthroplasty publication was increased from 1136 to 2771. For comparison with other studies we paid attention to the opinions of other researchers, many authors studied hip and knee arthroplasty separately [1; 4; 15; 25; 26] or summered together [2; 3; 5; 7; 16; 17] but none researches was conducted to study the ratio of the publication arithmetic mean hip and knee arthroplasty between hip and knee arthroplasty publications over the last 10 years. Although in our instance, having a lower number of publications, rate of increase the publication arithmetic mean of the knee arthroplasty was higher than hip arthroplasty publications. This can be understood, during the increasing the publication arithmetic mean of knee arthroplasty [3; 5; 15; 25] in parallel enlarged researches in this area [13; 14; 15].
In the next stage of our study we will take into account what the research productivity for several medical fields in various countries
has been studied and that shows the number of published articles is considered as an index of quantity of research productivity [14; 22; 23] And several researchers interested in regional and a linguistic criterion publishing [11; 14; 15; 28; 29; 30]. However our analyses present absolute incompatibility number of publication in EBSCO Health MedLine with objective quantity publication in a certain region or language (Figure 2). Knowing two sets of issues: General principles ofpublications in international journals and objective attitude to all publications, regardless of language differences forced us to answer some important questions. At first; The requirement to write only in English and the large number of publications in many of the database in English [28; 28], creates a very big problem for non-English-speaking authors, especially those countries which already has huge scientific potential in other languages. Secondly; large number of researches are conducted in many countries, in despite of the language barriers or economic status [6; 8; 10; 11; 12; 14; 15; 27; 29]. In the third; Studies show that many researchers for the solution of scientific problems lean to the much popular publication or publications with high impact factor [11; 12; 15; 24; 31] leave out of sight hard reachable or little-studied scientific works, even if they have great scientific value.
Despite the great effort to study all our aim, our study had a few limitations. Insufficiency of our method is the results will show only the scale of the studied databases and the result gives us the arithmetic mean of cited case in our databases, not number of publication. Although not one search system and none of calculation exist in our time cannot show or calculate the absolutely exact number ofpublications, we tried to find a more convenient and simpler solution to this problem and we took for our research three more accessible and more perfect search engines in our opinion, such PubMed, EBSCO Health Medline and the ScienceDirect..
Conclusion
The publication of materials knee arthroplasty have been sharply increased during the last years, it shows that the interest in study about problems knee arthroplasty have been increased in conjunction.
It is necessary to open more opportunities delivering these objects in international scientific publications and attract more researchers from different countries, for a more objective assessment an analysis of scientific data, despite their linguistic or other barriers.

New approaches to diagnostics and conservative therapy methods of flat- footedness in children
Abstract: The efficacy of the application of electrophysiological tests, including computer planography, which reflect characteristics of flat-footedness in children, was determined. Conservative therapy methods applied at the early stages of flat-footedness formation provide correction of the anatomical integrity and mobility of foot. Keywords: flat-footedness, diagnostics, conservative therapy, children.
On the modern stage of orthopedics development sufficient tients. That specialists' interest promotes detalization of pathologic attention is paid to the problem of flat-footedness; new multifunc- manifestations and design of high quality diagnostic and therapeutic tional devices are designed for diagnostics and treatment of the pa- methods. Earlier used strategies are replaced by more physiological
