In Early years spine surgery was done by slightly cutting the concerned area. It was similar to open heart surgery. So it is categorized as open surgery. However with the technological advancement in these last few years this open surgery has become more precise and less painful. This surgery needs a little opening on the concerned site which allows very little damage to the nearby muscle. There are several types of minimally invasive spine surgery and the include anterior longitudinal ligament resection, complex minimally invasive surgery with lateral approach, extreme lateral interbody fusion, lateral lumbar interbody fusion, percutaneous posterior pedicle screw fixation, minimally invasive surgical corpectomy, smith-Petersen osteotomy, pedical subtraction osteotomy and many more.
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.
