Osteochondroma is a type of tumor which is non-cancerous and forms near growth plate on the bone surface. It starts to develop during childhood or adolescence. In this condition there occurs the bone growth around the growth plate, and as the child body develops, along with the child growth, the osteochondroma also grow larger and the growth plates also harden and form solid bone. An osteochondroma is made up of both bone and cartilage and is the outgrowth of growth plate. When the child is fully developed, the osteochondroma also stops growing. So in most cases there is no treatment required except regular monitoring so as to identify any changes or complications. Osteochondroma may develop as a single tumor or multiple tumors. It may be congenital or may occur due to trauma to the growth plate that may have occurred previously.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
